Chernobyl is the explosive HBO show that has taken the world by storm and scored a higher IMDb than Game Of Thrones and Breaking Bad.
The five-part series follows an investigative commission appointed in the wake of the devastating nuclear accident on April 26, 1986.
The show has been lauded by many in the West as a harrowing and realistic account of those who battled to save the world from the toxic radiation emitting from the plant’s Reactor Four.
Yet its historical accuracy has now been brought into question, with a furious Russia planning to make its own series portraying the nuclear disaster as the work of an American CIA operative.
Here, MailOnline unpick the fact from the fiction in the series, looking at the main characters and what really happened to them.
Valery Legasov: The Soviet chemist
What happened in the show…
The show’s main character Legasov, played by Jared Harris, is a prominent Soviet inorganic chemist and a member of the bloc’s Academy of Sciences.
The deputy director of the Kurchatov Institute of Atomic Energy was in the series a nuclear physicist and picked by the government to look into the Chernobyl crisis less than a day after it happened.
At first he appears to bend to the will of the establishment – headed by Boris Shcherbina – but quickly changes tact as the scale of the disaster becomes apparent. He calls for the evacuation of the nearby city of Pripyat, which Shcherbina eventually sanctions.

The audience knows the fate of Legasov from the opening scenes in episode one, where the scientist hangs himself in a dingy house with his cat.
But possibly his most heroic actions are saved for the final two episodes.
Ulhana Khomyuk convinces Legasov to reveal to the world that there had been nuclear accidents in the Soviet Union before Chernobyl when he speaks at the trail of site operators Anatoly Dyatlov, Viktor Bryukhanov, Nikolai Fomin.
She tells him to expose the secrets regarding the same RMBK reactors that were at Chernobyl.
Legasov shows reservation, knowing if he told the truth his life would be in peril, but Khomyuk persists and reminds him of the countless people whose lives were devastated by the disaster.
The scientist gives his final speech in a courtroom and pulls through for Khomyuk, outlining the dangerous use of cheap materials.
And his fears are immediately realised as he is locked away and told his testimony will be erased. He is also told his scientific authority has gone and he has to cease communication with Shcherbina and Khomyuk.
What really happened…
The scenes with Khomyuk are all doctored, due to her being fictional, but much of Legasov’s explosive revelations were real.
Legasov, presented his findings to the International Atomic Energy Agency (IAEA) at a meeting from August 25 to August 29, 1986, in Vienna, Austria, rather than in a courtroom like in the programme.
The meeting was originally meant to be headed by Soviet leader Mikhail Gorbachev but he delegated to Legasov.
Foreign scientists from across the world heard him detail the causes of the accident.
He told them the explosion at reactor four was due to factors including construction flaws and human error from its staff.
He wrote in his report: ‘Neglect by the scientific management and the designers was everywhere with no attention being paid to the condition of instruments or of equipment.’

His five-hour testimony saw him praised by the western world, but he was, as in the series, in trouble back home.
Some scientists and politicians thought he had overstepped and revealed too much about Soviet secrets.
His daughter Inga Legasova told a Russian newspaper MK: ‘Father checked the numbers over and over again. He wanted to make sure all of the information was absolutely true.
‘He saw his main goal was not in justifying the Soviet Union and hide certain information, but, on the contrary, to educate the world community on what to do in such situations.
‘They gave the information that was allowed and the report was honest… I think the problem was not in secret data.
Confidential documents held in the National Archive in Kew, west London, show Legasov was unhappy with the way the reactor was built

‘The IAEA report made a huge impact and father instantly became very popular. He was named Person of the Year in Europe and was included in the list of the top 10 scientists in the world. This made some of his colleagues jealous.’
The rest of Legasov’s life was dogged by depression and he was irritated by the lack of research into preventing another Chernobyl.
Gorbachev was reported to have blocked him off the list of those to be awarded for the Chernobyl response, saying ‘other scientists don’t recommend it’.
But Inga added: ‘For some reason, many believe that my father was disappointed by the fact that he wasn’t awarded.
‘But he wasn’t, he wasn’t an ambitious man.
‘He was a patriot and grieved for what that happened, for the country, for people that suffered… His empathy was disturbed and, it seems, it did ‘eat him up from the inside’.’
She said he stopped eating and sleeping and was fully aware of what the radiation poisoning was going to do to him, adding that he likely ended his life on April 27, 1988, so he did not ‘burden my mother. He adored her’.
The V.I. Lenin Nuclear Power Station at Chernobyl, with its four RBMK nuclear reactors, was the pride of the Soviet Union (pictured: Valery Legasov towards the end of the Chernobyl TV mini-series)
He died by hanging the day after the second anniversary of the Chernobyl disaster.
But Boris Yeltsin did award him the posthumous honorary title of Hero of the Russian Federation in 1996.
He said it was for the ‘courage and heroism’ shown in his investigation.
Ulana Khomyuk: The fictitious female scientist
What happened in the show…
Khomyuk, played by Emily Watson, is another Soviet scientist and comes into the fold in the second episode.
The audience meets her at her lab at the Belarusian Institute for Nuclear Energy in Minsk as she discovers a dangerous amount of radiation leaking from Chernobyl was reaching her some 275 miles away.
She contacts Legasov and is brought in to help with the recovery operation at the forsaken power plant.
Ulana Khomyuk (pictured Emily Watson), another Soviet scientist, comes into the fold in the second episode.
The pair work out that if the ‘lava’ sitting underneath the reactor’s floor manages to leak into the water held below it, then the steam would create an explosion that had the potential to devastate all of the Eastern Bloc.
As the show progresses, Khomyuk, acting as the morally conscious character, begins to piece together what happened on the fateful night after interviews with the dying workers who were taken to Moscow for treatment.
Her apparent meddling sees her captured by the KGB but later released after Legasov pleads with them.
But Khomyuk continues to bravely call for those responsible for the disaster to be held accountable until the end of the series.
What caused the massive blast?
First, there was a hopeless lack of clear instructions. The rule book studied by shift foreman Alexander Akimov, contained a number of crossings-out.
There was an argument in the control room about which should be followed and which should not.
In particular, the team debated the power level at which it was safe to begin the test. The lower the power, the greater the chance of the reactor becoming unstable.
While the rules stipulated a minimum of 700 megawatts, Dyatlov insisted 200 megawatts were safe. He overruled Akimov. However, this proved academic when an error by Toptunov resulted in the power level being set to near zero.
At that level, the reactor was already showing signs of becoming increasingly unstable. The only safe option then was to increase the power again slowly, over a number of days. But Dyatlov was adamant the test went ahead. He gave the order to take the power level back up to 700 megawatts, a sudden and dangerous increase.
As a major drama series, Chernobyl, sheds new light on the impact of one of the world’s worst nuclear incidents
To achieve this, Akimov and Toptunov had to start pulling the boron control rods out completely, until only 6 of the 211 remained in place — the equivalent of taking the foot off the brakes.
This chain of decisions later led Dyatlov to be put on trial with other members of Chernobyl’s management. One of the prosecution witnesses was Valery Legasov, a prominent Soviet chemist played by Jared Harris in the Sky Atlantic drama.
Legasov initially toed the party line in putting the blame on the men, and Dyatlov in particular (the latter was sentenced to 10 years hard labour).
But he later incurred the wrath of the state by admitting that, while Dyatlov was very much culpable, he could not have known of a fatal flaw in the system which meant the system’s supposed fail-safe button actually acted as a detonator.
What really happened…
Khomyuk was made up.
She was a fictional character created to represent the rest of Legasov’s team of dozens of scientists who worked to stem the effects of the explosion.
Screenwriter Craig Mazin was part of the decision to build the female scientist’s character, which he said was not as unlikely a role as it sounds.
He told Variety’s ‘TV Take’ podcast: ‘One area where the Soviets were actually more progressive than we were was in the area of science and medicine.
‘The Soviet Union had quite a large percentage of female doctors.’
One of those not mentioned in the programme, who Khomyuk may represent, was Yuri Samoilenko, the Soviet official responsible for the decontamination from June, 1986.
From September 15 he had to look after reactors one and two as well as oversee the cleanup of the roof of number three.
When Samoilenko was told he had to finish the job by October 2 ahead of Gorbachev’s visit, he pleaded for more time to try to save the lives of the liquidators he had deployed on the reactor roof.
But it was to no avail, and he made his workers makeshift protective gear using lead from government buildings, which is seen in the television show as they dangle lead bands around their crotches.
Against the odds, in just 12 days, his team managed to remove 170 tonnes of radioactive waste.
The manual labour effort of 3,828 volunteers was necessary due to the failure of Soviet and West German robots, which could not copy with the radiation at the site.
In 1990, he acknowledged this for the first time, adding that innovative robotics equipment from the US were not used due to the Cold War conflict.
He said hazardous waste experts spent around £1.6billion on the cleanup as they used converted moon rovers as well as remote controlled bulldozers.
He told a conference at Carnegie Mellon University in Pittsburgh: ‘The challenge was to clear 100 tons of highly radioactive debris from the roof of the Chernobyl reactor.’
‘Unfortunately, we were not able to decontaminate the roof without using mostly manual labour.’
One of the scientists Khomyuk represented was Yuri Samoilenko (pictured with General Tarakanov flying over the Chernobyl site), the Soviet official responsible for the decontamination from June, 1986
A shocking scene in the show sees workers scamper across one of the roofs in short bursts as they throw radioactive material from it.
General Tarakanov sent the men up there, but said they were only forced to go up once, with some returning two or three times.
He told RT: ‘Only one was mandatory. But some volunteered to go twice or even three times. I recall Sergeant Cheban. The first time he got 8 rem, the second time 15. He earned five thousand rubles for each. But he did not do it for the money. He wanted to prove he could do it.
‘There was another guy, Stepanov, if my memory serves me right. He is in elevator maintenance now. He made three trips to the roof. A very strong man. He is still very strong. It all depends on your health.
He added: ‘In each case, before they could go again, they had to undergo all medical checks at the field hospital.
‘There was a very thorough control system in place, and all regiment and battalion commanders were personally responsible for each soldier’s life. And I, Major General Tarakanov, was responsible for the radiation exposure of each and every soldier, too.’
Boris Shcherbina: The deputy prime minister
What happened in the show…
The Soviet Union’s Deputy Prime Minister Boris Shcherbina is assigned by the Kremlin to lead the government commission on Chernobyl after the accident.
Boris Shcherbina was ‘calm and considered’, not like the character in Chernobyl
At the heart of the series is the unlikely alliance of Shcherbina, played by Mamma Mia!’s Stellan Skarsgard, and scientist Legasov.
After threatening to throw him out of a military helicopter when he questions the official Soviet line on the disaster, Boris starts to respect Valery and they work together.
He had wanted to downplay the disaster, in a way that would appease his bosses in the Kremlin, but he steadily realises it would be a lie.
Stellan said: ‘Boris was a notorious yeller, sent to sort problems by shouting at people.
‘But he knew Chernobyl couldn’t be covered up, as the Soviet hierarchy wanted: their supposedly perfect system failed.’
How do nuclear reactors work?
As an expert trial witness in the programme painstakingly explained, in the Soviet-designed RBMK-1000 nuclear reactor’s core, there were more than 1,600 fuel rods of radioactive Uranium-235.
This form of uranium is unstable, meaning its atoms are constantly breaking down — a process called fission — to release sub-atomic particles called neutrons.
It is a process that produces enormous heat and energy. And this has to be kept under careful control.
So to keep the core cool, and not dangerously overheat, a series of pumps sends a constant flow of water through it, which heats up, producing steam which then powers turbines to produce electricity.
To control the amount of energy (heat) produced by the core, the operators can manage the level of reactivity, increasing it or decreasing it, by inserting or removing control rods made of boron which absorbs neutrons, slowing the nuclear reaction down.
In effect, the boron control rods act like the brakes on the car. There were 211 such rods within the Chernobyl reactor.
Dramatic scenes in Chernobyl when engineers try to stabilise the reactor by pressing the AZ-5 failsafe button
What really happened…
Shcherbina had been summoned from a business trip to Siberia after the accident took place.
He got to Prypiat, where those who worked on the nuclear plant lived, at about 8.00pm on April 26 – just 18 hours after the explosion.
But despite Stellan’s description, Shcherbina was said to be ‘calm and considered’, especially considering the hardy life he mostly led in Siberia.
Boris Shcherbina, chairman of the governmental commission investigating the Chernobyl nuclear power station disaster, speaks at a news conference in Moscow on May 7, 1986
He knew about the oil and gas industries after spending most of his time in politics visiting Siberia, but knew little about nuclear power, which is presented in HBO’s show.
One scene sees Shcherbina fly to Chernobyl with Legasov from Moscow, where the scientist introduced the politician to the physics of a nuclear reaction.
It is highly likely Legasov did tutor Shcherbina on the science, but it would not have been conducted on a helicopter flight from Moscow.
The 433 miles to Chernobyl was too far to take by helicopter, and in the true event they were flown by plane to Kiev before driving to the forsaken city.
The 433 miles to Chernobyl was too far to take by helicopter, and in the true event they were flown by plane to Kiev before driving to the forsaken city
Shcherbina’s calm nature, combined with the fact Legasov was an esteemed member of the Soviet Academy of Sciences, make it also very unlikely he threatened to chuck him out of the helicopter.
Legasov informed Shcherbina early on that the radiation he had been exposed to would kill him, and the final episode saw him coughing up blood into a handkerchief.
Shcherbina, unlike Legasov, lived on until August 22, 1990, when he died in Moscow, as the end credits of the show state.
But it is uncertain as to whether he died because of the radiation in his body, due to a 1988 decree preventing Soviet doctors from citing radiation as a cause of death.
The daring divers told they would die:
What happened in the show…
In the hit mini-series, the bravery of the three engineers is one of the most dramatic moments of the show.
Oleksiy Ananenko, now 59, was hailed as one of the heroes who stopped Chernobyl from being even worse than it was
Officials tell workers about the imminent danger of a second explosion and the three men volunteer for the mission to prevent ‘millions’ of deaths.
In the episode, actors playing Oleksiy Ananenko and two other engineers, Valeriy Bespalov and Boris Baranov, attempt to empty a water tank located ten feet below the burning reactor.
Nuclear experts feared that a second explosion could take place if super-hot radioactive fuel burned through a concrete floor and reacted with the large amount of water in the tank.
Protected only by diving equipment and simple respirators, the three men negotiated the partially flooded corridors under the reactor.
Using flashlights, they managed to find the locks for the water tank in the dark and quickly opened them.
What really happened…
Mr Ananenko, now 59 and living in a modest one bedroom apartment on the outskirts of Kiev, has insisted that what he did was not heroic.
Despite the fears of a second explosion, the scale of the disaster was unclear at the time.
Mr Ananenko said: ‘I never felt like a hero. I was doing my job.
‘I was ordered to go there, so I went. I wasn’t afraid.’
In the hit mini-series, the bravery of the three engineers is one of the most dramatic and gripping moments of the show
He added that the three men depicted in the series as volunteering for a suicide mission simply obeyed orders, without being clearly informed about the risks they incurred.
Mr Ananenko said: ‘Immediately I heard a noise that meant the water was draining. That was amazing.’
However, watching the scene play out in the TV series, he pointed out some inaccuracies.
Pointing at the oxygen cylinders, he said: ‘We didn’t have them.
‘And we walked quicker than that. Why quicker? Because if you went slowly, the dose (of absorbed radiation) would be higher.’
Mr Ananenko said that the three men depicted in the series as volunteering for a suicide mission simply obeyed orders
Despite carrying two dosimeters with him, Mr Ananenko said he does not recall the exact figure for the amount of radiation his body absorbed.
‘That means it wasn’t very high,’ he said.
Of the three engineers, Mr Bespalov is also alive, living in the same district as Mr Ananenko.
But Mr Barano died in 2005.
Mr Ananenko did not suffer any serious health problems straight after the mission and he was able to continue to work in the nuclear sector until 2017.
However, the Chernobyl veteran was forced to retire because he was involved in a serious car accident that plunged him into a coma for a month and affected his memory.
Decorated with Soviet and Ukrainian medals, Mr Ananenko now receives a monthly state pension of around $417 (369 euros).
The 400 miners who dug a tunnel underneath the reactor:

They are trying to stop uranium from getting into the ground water and then the Black Sea, which would affect all of Europe.
Horrific scenes show the miners working around the clock in blistering heat as they carve the hole.
The closing credits said around 100 of the miners died before the age of 40.
What really happened…
The scenes are understood to be generally true. They worked day and night for over a month, battling heat of around 122F (50C) with no ventilation to build a 150 metre tunnel.
The show sees the miners strip off from their limited protective clothing and work naked – aside from their miners’ hats and shoes.

It is also true that one out of every four miner died before the age of 40.
Tragically, the heat exchanger the miners had risked their lives for was never put in due to the fuel chilling unaided.
But one miner has said: ‘Perhaps it’s a sin to say so but it was a wonderful time.
‘I didn’t want to leave that place. That was the way we related to one another.’
Lyudmilla Ignatenko: The widowed pregnant mother
What happened in the show…
Ignatenko’s was a heartbreaking story that continues throughout the series.
Her firefighter husband Vasily endured two weeks of agony before dying from radiation poisoning aged 25, with Lyudmilla – played by Jessie Buckley – constantly at his bedside as his body underwent horrifically graphic changes.
Lyudmilla Ignatenko, played by Jessie Buckley (pictured), lost her daughter Natashenka in Moscow two months after husband Vasily died
During the programme, the audience watches in horror as Lyudmilla, then 23, touches her husbands deteriorating skin, in the knowing it would impact on her and her unborn baby.
What really happened…
Ignatenko retold her memories in the book Voices From Chernobyl in 2005.
She said of her husband: ‘Any little wrinkle [in his bedding], that was already a wound on him.
‘I clipped my nails down till they bled so I wouldn’t accidentally cut him.’
The extract appears to support the notion she touched him, which, on the small screen, she was warned not to by the fictional Ulana Khomyuk due to her being pregnant.
Ignatenko (pictured at the first commemorative ceremony in homage to liquidators who died from exposure to radiation) retold her memories in the book Voices From Chernobyl in 2005
Her interactions with Khomyuk may have been fake, but the child was real, with Lyudmilla giving birth to Natashenka in Moscow two months after Vasily died.
The baby girl died just four hours after birth due to cirrhosis of the liver.
The end credits of Chernobyl also note how Ignatenko disproved doctors by having another child.
This was true, as she gave birth to Andrei, short for Andreika, who she had with another man after she set up in an apartment in Kiev.
She told the book’s author: ‘My friends tried to stop me. ‘You can’t have a baby.’ And the doctors tried to scare me. ‘Your body won’t be able to handle it’.
The credits do not reveal anymore on how her and her son live, however.
Ignatenko tells how her boy came out perfectly, with none of the missing limbs the physicians had warned.
Ignatenko even said Andrei helped her recover from her first stroke.
But added that he is ill, spending ‘two weeks in school, weeks at home with the doctor’.
The helicopter pilots killed falling into the reactor:
What happened in the show…
One of the most gripping scenes in the series is the Vietnam-style journey of a team of helicopters flying over the power plant.
The military personnel fling sand, lead and boron at the reactor to try to stem the fire caused during the explosion.
But one gets too close, becomes immersed in the deadly smoke and collides with a crane.
One of the helicopters in the series gets too close to the reactor, hits a crane and plummets to the ground, killing all occupants. It is a true story
Legasov and Shcherbina helplessly watch on as it spirals into the reactor, killing all those on board.
In episode two of the HBO show, this happened during the immediate recovery period after the incident.
What really happened…
The crash was real, but it took place months later in October, with the timeline being altered so the producers could show the horrors the pilots had to deal with.
Some of the aircraft even had their doors open so the soldiers could throw the materials out.
Show creator Craig Mazin told Men’s Health: ‘I wanted people to know that this was one of the hazards that these pilots were dealing with — an open reactor. Radiation was flying over it.’
Jan Haverkamp, a senior nuclear energy expert at Greenpeace, added that the air around the reactor was hard to judge, but confirmed it was the collision with the crane that caused the crash.
Five types of helicopter were used in the response to Chernobyl. These were the Mi-2 Hoplite, Mi-6 Hook, Mi-8 Hip, Mi-24R Hind and the Mi-26 Halo.
Colonel Oleg Chichcov said years later: ‘Before the accident there were huge cranes around the reactor. After the explosion, some of these were literally hanging in the void without support.’
The a Mi-26 helicopter instructor refused to fly into the area until the ‘cranes were made safe’ and so the fateful Mi-8 chopper was sent and ultimately crashed.
The shocking original footage of the crash only emerged after the fall of the Soviet Union in 1991.
Those helicopters used during the initial two-week clean up period were too contaminated to fly again and had to be scrapped in an undisclosed location until they were later destroyed.
The three ‘villains’: Viktor Bryukhanov, Nikolai Fomin and Anatoly Dyatlov
What happened in the show…
Bryukhanov, Fomin and Dyatlov are presented in the HBO show as the bad guys from the outset, showing incompetence in sanctioning a late night safety test, despite being warned of the dangers.

The series of events that led to the explosion in the reactor at Chernobyl
What was the fatal build up to Chernobyl?
Located about 81 miles north of the city of Kiev in the Ukraine, the Chernobyl Nuclear Power Plant consisted of four reactors built in the Seventies and Eighties.
The cooling water was provided by a man-made reservoir fed by the Pripyat River.
The plant was an important contributor to the Soviet economy, powering 30million homes and businesses and provided 10 per cent of Ukraine’s electricity needs.
The accident happened in Reactor Four, which was completed at the end of 1983. The plant director, Viktor Bryukhanov, signed a certificate to say it had undergone all of its final safety tests.
In fact, Bryukhanov was rushing to meet a deadline — for which he was later rewarded with the prestigious title of ‘Hero of Socialist Labour’ — and the reactor still had to undergo one vital test.
This was to check whether in the event of a power blackout — caused by equipment failure or perhaps attack by a foreign enemy — the power in the slowing turbines would be enough to keep the water pumps going until back-up diesel generators could kick in.
To test the theory, the turbines would be switched off and, as they slowly wound down, their electrical output would be measured to see if indeed they did provide enough to power the water pumps.
This test was due to take place on the afternoon of April 25, 1986. But at the last minute the officials running the power-grid demanded it be delayed until the end of that day’s production in local factories.
It was postponed until midnight, by which time the day staff had gone off duty. They were replaced by a far less experienced night shift, including 25-year-old Leonid Toptunov who was responsible for controlling the reactor. He had been in the job for just four months.
Toptunov was certainly no match for his bullying manager, deputy chief-engineer Anatoly Dyatlov, whose promotion depended on the test being performed successfully. Nobody in the control room had experience of such a procedure.
They remain in the background in the following episodes as they battle radiation poisoning, until the finale, which jumps forward to their trial in July 1987.
The final show flicks from the trial to the night of the incident, showing how they played a role in the disaster, with Bryukhanov portrayed as a bullying character and the others obsessed with the test and results.
What actually happened…
Bryukhanov, Fomin and Dyatlov accepted professional responsibility for the accident but denied criminal liability.
They were sentenced to ten years in a labour camp, which was the maximum possible punishment for the disaster.
Bryukhanov, in particular, has spoken out about his role in the incident.
He was the director of the plant, while Fomin was chief engineer and Dyatlov was deputy chief engineer.
In a rare interview in 2006, Bryukhanov sensationally claimed scientists covered up the truth about faults with the reactor.
He had been jailed for a decade for his part in the incident and Russia’s Profil magazine: ‘You need to understand the real causes of the disaster in order to know in what direction you should develop alternative sources of energy.
‘In this sense, Chernobyl has not taught anything to anyone.’
The trial of Viktor Bryukhanov, Nikolai Fomin, Anatoly Dyatlov in 1987
He does admit that he and his workers made errors, but added that any official investigation had been whitewashed to excuse the nuclear industry worldwide.
He added: ‘The scientists, the construction engineers, the prosecution experts, they all defended their professional interests and that was all. It was a tissue of lies that distracted us from the search for the real causes of the accident.’
The official probe into the accident was part of a broader, international cover-up about the risks of nuclear power, Bryukhanov said, though he offered no evidence to back this up.
‘(It’s) not just us: the Americans, the French, the English, the Japanese, are all hiding the real causes of accidents at their own nuclear power stations,’ he said.
Bryukhanov was at his home near the plant when the reactor blew up and bore most of the responsibility at the trial, according to the New York Times.
He served half his ten-year jail sentence and now lives in the Ukrainian capital, Kiev, the magazine said.
Fomin, the chief engineer, was a trained electrician, according to the Associated Press, and was around the age of 50 at the time of the incident.
Was the safety button a deadly catalyst?
In the control room of every nuclear reactor, there is an emergency button which, when pressed, inserts all the boron control rods into the core in one go and brings the nuclear reaction to a dead halt. But at Chernobyl — and many other Soviet reactors — this fail-safe was fatally compromised, as highlighted by Legasov.
The Soviets had cut costs by making the tips out of the rods out of graphite, much cheaper than boron. But graphite, far from stopping the reaction, actually accelerates it. This would usually be counteracted by the boron in the rest of the rod — but in the extreme and unusual circumstances that night in Reactor Four the boron had no chance to kick in.
At 1.23am, the AZ-5 emergency button was activated. As the rods were inserted back into the core to slow the reactor, the presence of the graphite tips resulted in a skyrocketing of the reaction in the core.
This converted every last molecule of water into steam which expanded and ruptured the fuel-rod channels, fixing them in position so the boron rods could no longer be pushed into the core, and endlessly accelerating the nuclear reaction in an unstoppable chain reaction.
The temperature in the reactor reached 4,650c — almost as hot as the sun’s surface — and triggered a huge explosion as a build-up of steam blasted the 1,000-ton plate covering the reactor into the air.
This was the first of a series of explosions which ‘vaporised’ into the atmosphere some 50 tons of radioactive uranium which has a half-life (the time it takes for the radioactivity to fall to half of its original value) of 700 million years. A further 70 tons were scattered around the area.
He had a mental breakdown before the trial and attempted suicide using smashed glass from his spectacles to cut his wrists.
It delayed the trial and he reportedly tried to kill himself again after he was sentenced.
Fomin had a nervous breakdown after he was caged and was released early due to it.
Information on Fomin from after his sentencing is scarce but his consistent exposure to the toxic air makes it likely he has faced severe health problems.
Dyatlov strongly disagreed with his sentencing and the argument he did not take enough precautions.
He told the Washington Post in 1992: ‘I found myself confronted with a lie, a huge lie that was repeated over and over again by the leaders of our state and simple technicians alike,’ he said of the story put forth by Soviet officials.
‘These shameless lies shattered me. I don’t have the slightest doubt that the designers of the reactor figured out the real cause of the accident right away but then did everything to push the guilt on to the operators.’
He added: ‘If I had known then what I know now about what kind of monster this reactor was, I would never have gone to work at Chernobyl. And not only me. Nobody would have worked there.’
Dyatlov’s defence also comes from another engineer at the plant during Chernobyl.
Oleksiy Breus views the characters in the show as ‘not a fiction, but a blatant lie’.
He told the BBC: ‘Their characters are distorted and misrepresented, as if they were villains. They were nothing like that.’
‘Possibly, Anatoly Dyatlov became the main anti-hero in the show because that was how he was perceived by the power plant’s workers, his subordinates and top-management, in the beginning. Later this perception changed.’
Mazin still claims that Dyatlov was a bully, with Mr Breus agreeing: ‘The operators were afraid of him.
‘When he was present at the block, it created tension for everyone. But no matter how strict he was, he was still a high-level professional.’
Mikhail Gorbachev: The Soviet leader
What happened in the show…
Gorbachev plays a lesser part in the programme as scenes sporadically cut to Legasov, Shcherbina and Khomyuk briefing him on any updates to the situation there.
The Soviet leader, played by Swedish actor David Dencik, leaves the commission to investigate and appears to rely on their updates for information.
Gorbachev, played by Swedish actor David Dencik, leaves the commission to investigate the disaster
What really happened…
Chernobyl was headline news in the West.
Supported by the KGB, the Soviet nuclear industry was determined to suppress the truth – that the Chernobyl disaster was the conclusion to years of lying and ingrained incompetence.
There was no mention of any design faults in the reactor. But behind closed doors, Gorbachev and the Politburo already knew the facts – and that the Soviet nuclear industry had been hiding a terrible secret.
They had known since 1975 and the Leningrad accident that one of their reactors was likely to explode – and with unspeakable consequences.
It is a particular irony that by spring 1986, Chernobyl was, officially, one of the best-performing nuclear stations in the Soviet Union, and scheduled to receive the Order of Lenin, the state’s highest honour.
But the former Soviet leader his hit out at the way he is portrayed in the show, saying it was not his decision not to award Legasov for his efforts
Even the destruction unleashed by Reactor Number Four could not match the explosive political consequences that would follow.
Gorbachev’s personal reputation in the West as a reformer had been tarnished.
But he has accused the Soviet nuclear establishment of presiding over a secret state.
‘For 30 years, you told us that everything was perfectly safe. You assumed we would look up to you as gods,’ he said. ‘That’s the reason why all this happened, why it ended in disaster.’
Gorbachev has also hit out ‘inaccuracies’ in the HBO show.
Last week he told Pravda he had not refused to reward Legasov the title of Hero of Socialist Labour.
The reformer, known for his Glasnost policy of open discussion of political and social issues, said: ‘I did not give [orders]. Who else could give them, but me? This is fiction.’
Despite this, he admitted he had not seen the series.
How did the Chernobyl disaster unfold minute by minute?
by Jonathon Mayo for the Daily Mail
The V.I. Lenin Nuclear Power Station at Chernobyl, with its four RBMK nuclear reactors, was the pride of the Soviet Union, generating electricity for 30 million homes and businesses.
It was an operating system the West had rejected because of concerns about design flaws and its safety, but the Soviets were confident it was secure. In an interview in February 1986, Vitali Sklyarov, the Minister of Power and Electrification of the Ukraine, said: ‘The odds of a meltdown are one in 10,000 years.’
As a major drama series, Chernobyl, sheds new light on the impact of one of the world’s worst nuclear incidents — ranked equal with Fukushima in Japan, in 2011 — JONATHAN MAYO reveals, in gripping detail, how the catastrophe unfolded minute by minute…
As a major drama series, Chernobyl, sheds new light on the impact of one of the world’s worst nuclear incidents
Friday, April 25, 1986
It has been an unseasonably warm day at Chernobyl, in northern Soviet Ukraine, and the cherry trees are already in bloom. In the shadow of the power station, scores of fishermen are settling on the edge of a large artificial pond — its waters are used to cool the plant’s four giant reactors. Power station bosses boast that the water is so safe they are breeding fish there. Angling is prohibited but the fishermen know that at this time of night no one will bother them.
Anatoly Dyatlov, Chernobyl’s 55-year-old deputy chief engineer, arrives at work. Tonight he will be overseeing a test authorised by the Soviet Energy Authority to assess the plant’s ability to keep its latest reactor, No 4, cool in the event of a power cut.
The test should have been carried out before the reactor became operational in 1984, so it is two years overdue.
The son of a Siberian peasant, Dyatlov has risen to become the leading nuclear expert at Chernobyl. He is an intolerant manager and keeps a notebook to write down the names of those who cross him.
engineer Sasha Yuvchenko, 24, clocks on for the night shift. The tall young man is one of 176 workers at the power station tonight. He changes into regulation white overalls and cap and makes his way to his office, between Reactors No 3 and No 4, to be briefed by the engineer he is taking over from.
A former champion rower, he has just said goodbye to his wife Natasha and their two year-old son Kirill in the nearby city of Pripyat, built from scratch in 1970 to house the thousands of workers at the plant. It now has a population of just under 50,000.
The nuclear industry is prestigious and Pripyat’s supermarkets are better stocked than most in the Soviet Union. It has good schools and sports facilities.

Saturday, April 26, 1986
The large control room of Reactor No 4 is harshly lit by fluorescent lights and full of cigarette smoke. The atmosphere is tense. No one has done a shutdown test like this before.
Anatoly Dyatlov is arguing with the shift foreman, Alexander Akimov, about the level of power produced by the reactor at which it is safe to begin the test. The lower the power, the more danger there is of an accidental shutdown.
The rule book, which Akimov has in his hands, stipulates that it should be no less than 700 megawatts, otherwise the reactor will become unstable. Dyatlov insists that 200 megawatts is safe. Akimov is outranked by Dyatlov, so he reluctantly agrees to allow the test to continue.
The reactor control engineer, 26-year-old Leonid Toptunov, who has only been in his job a few months, switches the system from manual to automatic. But he misses a vital step, failing to select a megawatt level at which the control room computer would then operate.
The computer defaults to the last level that had been inputted — near zero. Power in Reactor No 4 falls almost to zero megawatts. The reactor is now unstable and has the potential to explode.
Alarms begin to sound. Alexander Akimov says that the rulebook states the test should now be aborted. But Dyatlov wants it completed and insists they continue. That the reactor might explode is unthinkable to him.
In the reactor’s core are more than 1,600 radioactive uranium-235 metal fuel rods. Uranium-235 is unstable, its atoms constantly breaking down to release subatomic particles called neutrons — which hit more uranium atoms, so triggering a chain reaction that generates enormous heat and energy.
In a controlled chain reaction, this heat can be used to turn water into steam that powers a turbine to generate electricity.
Control of the reaction depends on 211 boron control rods spread throughout the reactor’s core. They can absorb neutrons and so slow the chain reaction.
If the rods are raised, the chain reaction accelerates. If they are taken out altogether, the engineers lose their ability to stop the reactor overheating.
In an attempt to lift the power level, Dyatlov orders the control rods to be raised. Alarmed by the likely loss of control, Toptunov refuses to do so.
Threatened with the sack by Dyatlov, Toptunov finally agrees to raise the control rods and the reactor is powered up to what is regarded as a safer 200 megawatts. But it is increasingly unstable.
The control room computer is demanding that the reactor be shut down, but the test is scheduled to begin. Alexander Akimov hesitates over the controls. ‘What are you waiting for?’ Dyatlov says impatiently.
In an interview in February 1986, Vitali Sklyarov, the Minister of Power and Electrification of the Ukraine, said: ‘The odds of a meltdown are one in 10,000 years’ (pictured: Chernobyl TV miniseries)
1.23 and 40 seconds
The temperature in the reactor is now 4,650c — almost as hot as the surface of the Sun. Akimov presses the button to start the test, inadvertently starting a catastrophic chain reaction that generates enormous amounts of steam.
Suddenly, Valeri Perevozchenko, an engineer who had been on a catwalk high above the reactor, bursts into the control room in a panic, shouting that he has seen the 350kg (772lb) caps on the fuel rods jumping up and down in their sockets. Then the control room walls start shaking and the men hear a sound like a long, low human moan — followed by a huge explosion as a build-up of steam blasts the 200-ton concrete shield above the reactor into the air.
In the control room, Akimov shouts: ‘Shut down the reactor!’ But it is too late.
1.23 and 45 seconds
There is a second, much louder blast as 50 tons of radioactive uranium fuel from the reactor core — ten times the amount at Hiroshima — vaporises and is blasted into the atmosphere. Uranium-235 has a half-life (the time it takes for the radioactivity to fall to half its original value) of 700 million years.
A further 70 tons of uranium and 900 tons of radioactive graphite is scattered around the surrounding area, including on Reactor No 3.
In No 4’s reactor core, 800 tons of graphite start to burn, sending more lethal radioactive material 3,000 ft into the night sky. The men fishing by the cooling pond are illuminated by the flames.
In the control room, dust and debris are falling from the ceiling and the terrified technicians think they are in the middle of an earthquake. No one imagines it could possibly be the reactor.
More alarms sound, the fluorescent lights go off and the emergency generators kick in.
Sasha Yuvchenko is in the senior engineer room, talking to a colleague who has come to collect a tin of paint, when a shockwave hits the room. ‘The metre-thick concrete walls were bent like rubber. I thought war with the Americans had begun,’ he later said.

Everywhere there is an ominous hissing noise. Yuvchenko runs from the room and, behind a pile of rubble, finds a badly scalded and bloody pump operator, who tells him he must rescue their colleague Valery Khodemchuk, who is in the main circulating pump room close to the explosion. ‘He’s still trapped in there!’
Outside Paramilitary Fire Station Number Two, 500 yards away, firemen enjoying the cool night air watch in horror as a giant mushroom cloud of smoke rises from the power station. In their operations room, hundreds of red lights are flashing — one for every room in the power plant.
The crews run to their trucks. In charge is youthful but respected 23-year-old Lieutenant Vladimir Pravik. On his radio, he summons every fire crew in the region.
At his home in Pripyat, Viktor Bryukhanov, the director of the Chernobyl plant, is woken by a phone call. His wife watches as the colour drains from his face. Bryukhanov gets dressed and leaves without saying a word.
Sasha Yuvchenko is still searching for Valery Khodemchuk in the reactor building. He looks up and sees stars — the ceiling has disappeared.
Sparks are showering from severed power cables and a blue-white beam of radiation from the core is shooting upwards.
‘I remember thinking how beautiful it was,’ Yuvchenko said afterwards. There is no sign of Khodemchuk.
The control room of Reactor No 4 is filled with dust. A shocked Dyatlov is trying to understand what has happened. Unaware that the reactor is a blazing volcano, he hopes water might save it from damage and orders Akimov to activate the emergency cooling pumps. ‘We’ve got to get water into the reactor!’
On A ledge more than 100ft up in the remains of the main reactor hall, three technicians are looking down into the blazing reactor. A few yards away, Sasha Yuvchenko is straining to hold the steel and concrete reactor hall door open. It has come off its hinges. If it closes, his three colleagues will be trapped inside.
Yuvchenko doesn’t realise that radiation from the door is already attacking his skin. Although the three men on the ledge are only there for a minute, the radiation will kill them in less than two weeks. Sasha Yuvchenko will die of leukaemia in 2008.
The fire crews from Paramilitary Fire Station Number Two arrive at the power station. They are stunned to see that the roof of Reactor No 4 is missing.
Lieutenant Pravik says to his colleague Leonid Shavrey: ‘We’ll really have our work cut out here.’ Shavrey knows they are heading into danger. ‘My hair stood on end,’ he later said.
There is a strange vapour in the air.
Viktor Bryukhanov, the director of the plant, drives through the gates and sees the devastation for the first time. He knows his career is over.
‘I’m going to prison,’ he thinks.
He had overseen the building of the power station and, like many Soviet officials, had cut corners, signed off tests that were never conducted and hit targets by reducing the time spent in making urgent repairs.
Bryukhanov orders that the power station’s underground bunker — built as a command post in case of nuclear war — be opened, then tells his managers to assess the situation in their departments and report back to him. Soon the bunker is filled with 40 men, all frantically making telephone calls.
In the rubble of the kilometre-long turbine hall that links all four reactors, a team of engineers armed with a single torch are searching desperately for their colleague Vladimir Shashenok. They find him barely alive, badly burned and with bloody foam coming out of his mouth. They pick him up and carry him to safety.
Above them on the burning turbine hall roof, firemen Leonid Shavrey and Vladimir Pryshchepa are trying to extinguish the flames. Reluctant to use water because of the danger from exposed electricity cables, they are throwing sand on the fires and beating them out with their canvas hoses.
Contrary to fire regulations, the roof is covered with highly flammable bitumen. Shavrey later recalled: ‘With the slightest increase in temperature, the bitumen immediately caught fire. If you stepped on it, you couldn’t put one foot in front of the other — it tore off your boots.’
The men have no training in putting out fires such as this, and are kicking away burning debris with their boots, not realising that it is radioactive.
Dr Valentyn Belokon, 28, arrives from Pripyat Hospital armed only with painkillers to treat burns. But there are no burns victims yet. A young worker from Reactor No 3 is brought to him suffering from nausea and a violent headache. Belokon assumes the man was drinking the night before.
The young fire chief, Lieutenant Pravik, is concerned that the roof of Reactor No 3 (built close to Reactor No 4 to save money) is now on fire. A westerly wind could spread the flames farther, to Reactors 1 and 2, which are both still operating.
Even though Pravik’s walkie-talkie isn’t working and they have no anti-radiation equipment, he bravely leads his men up a fire ladder to the roof of Reactor No 3.
On the roof of the turbine hall, fireman Leonid Shavrey is getting so hot he removes his helmet. The fishermen, still by the cooling pond, see this and cheer what they think is bravado. ‘He’s taken his helmet off!’ says one. ‘He’s a real hero!’
In Reactor No 4’s control room, Anatoly Dyatlov, the dogmatic deputy chief engineer, is told by a technician that the reactor has blown up. Dyatlov refuses to believe it and heads outside to see for himself. He is stunned by the apocalyptic scene before him.
The local fire brigade chief, Lieutenant-colonel Leonid Teliatnikov, has assembled a team of 28 men to put out the reactor fires. Thoughts of his family flash through his mind, but his main worry is that his men won’t have the strength to keep going until reinforcements arrive.
The condition of the young man Dr Belokon thinks is hung over worsens. He is very pale and continually muttering ‘The horror of it! The horror of it!’ Belokon gives him a sedative. More men appear with similar symptoms.
Leonid Shavrey’s younger brother Petr, who is also a fireman, arrives at the power station not wearing any protective gear, as he was off duty when the emergency call came. He hears Leonid shout from the turbine hall roof that he has no working hoses, so Petr puts two under his arms and clambers up the fire ladder. ‘Protection didn’t matter but time was of the essence to stop the flames spreading,’ he later said.
Lieutenant Pravik and his men come down from the roof of Reactor No 3, as they are all starting to feel sick. Someone calls an ambulance. As Pravik is helped inside, he asks a colleague to phone his wife and tell her to close their apartment’s windows. Pravik’s eyes have turned from brown to blue. He has only days to live.
Fireman Alexander Petrovsky, 24, has taken Pravik’s place and is making his way to the top of Reactor No 3. He is shocked to find only one hose is working.
The power station’s civil defence chief, Serafim Vorobyev, is using a military radiometer designed for use in a nuclear attack to measure radiation. It shows levels are 100 times higher than normal. He runs to Viktor Bryukhanov, the director of the plant, and tells him they need to warn the citizens of Pripyat to stay indoors.
Bryukhanov tells him to go away — he needs time to think.
The firefighters on the roof of the turbine hall have run out of water because the electric pumps have failed. Petr Shavrey, still with no protective gear, has decided the only option is to use water from the cooling ponds. But first he has to guide large fire trucks around the huge amount of debris from the explosion that is surrounding the power station.
As Petr runs in front of the first truck, moving obstacles out of the way, its tyres are punctured by metal spikes. He grabs one with both hands and the skin on his palms peels away.
On top of Reactor No 3, firefighter Alexander Petrovsky goes blind for 30 seconds. When his sight returns, he says to his colleague: ‘Let’s get the f*** out of here!’
All the operators who were missing after the explosions have been accounted for except Valery Khodemchuk, who, unbeknown to his colleagues, was vaporised.
Anatoly Dyatlov from the control room joins the search, with turbine engineer Valeriy Perevozchenko. Their progress through the engine room is hampered by concrete rubble and a fallen crane.
Perevozchenko manages to partially open an office door — and as he shouts Khodemchuk’s name, he is showered by radioactive water cascading from broken pipes overhead. His search for Khodemchuk will ultimately kill him.
Viktor Bryukhanov, the power station’s director, is calling his bosses in Moscow to give them an update.
He downplays the situation, saying that although there has been an explosion, only part of the turbine hall roof has collapsed and the reactor is still intact and being cooled down by his engineers.
Finally realising the firemen and nuclear workers he is seeing are suffering from the effects of radiation, Dr Belokon calls the hospital in Pripyat to ask for potassium iodide — a drug that offers some protection from radiation — to be brought to Chernobyl.
The power station’s civil defence chief, Serafim Vorobyev, is continuing to measure radiation levels, but his clothes and body are so contaminated he can no longer get an accurate reading. Vorobyev angrily confronts his boss, Viktor Bryukhanov, again.
‘There’s no mistake! We have to take action!’
Bryukhanov shoves him away. ‘Get out! Your instrument must be broken!’
Fire chief Leonid Telyatnikov starts vomiting. ‘I thought I was just tired from rushing around so much,’ he said. ‘I was somehow sure I couldn’t get ill because I still had so many things to do.’
After watching the efforts of the firefighters for almost three hours, the fishermen by the cooling ponds are starting to feel ill. Two of those fishing closest to the plant will die.
The newly installed General Secretary of the Communist Party of the Soviet Union, Mikhail Gorbachev, is woken by a phone call telling him there has been a fire at the Chernobyl nuclear power plant. Even he is not told the whole story.
‘In the first hours and even the first day after the accident there was no understanding that the reactor had exploded and there had been a huge nuclear emission into the atmosphere,’ Gorbachev later recalled.
Fire chief Leonid Telyatnikov and his men have arrived at Pripyat hospital. They are chatting and smoking.
They think they are there for a routine post-fire check, but within a few days they will develop radiation burns on their faces, hands and feet.
Six of the men will die. The survivors, including Telyatnikov himself, are later taken to a sterile unit in the specialist radiological wards of Moscow’s Hospital No 6. He won’t be well enough to leave hospital for eight months.
‘Chernobyl showed us that some people are not as conscientious and upright as they should be. We did what we had to do and that’s all,’ he said afterwards.
Anatoly Dyatlov, weakened by sickness and with his shoes soaked by radioactive water, reports to the plant’s director, Viktor Bryukhanov, who asks him how the disaster happened.
‘I don’t know. I don’t understand any of it,’ Dyatlov replies. Both Dyatlov and Bryukhanov will be sentenced to ten years in prison for their role in the disaster.
The sun has now risen, revealing the full horror of the wrecked V.I. Lenin nuclear power station.
The fires are under control, thanks in part to water from the cooling pond. Firefighter brothers Leonid and Petr Shavrey are exhausted. Petr is desperate for a drink and grabs a water hose. ‘What are you doing? It’s filthy!’ a colleague yells at him.
Petr knows by now that the water is probably radioactive but he doesn’t care: ‘It seemed to me that if I didn’t get a couple of gulps, I would collapse and wouldn’t be able to get up again.’
That brief drink will cause lasting damage to Petr’s digestive system.
The deputy fire chief for the region declares optimistically that the emergency is over.
Alexander Akimov and Leonid Toptunov, the two control-room technicians who had argued with Anatoly Dyatlov before the test began, are in the bowels of Reactor No 4 on a futile mission, trying to get water to the wrecked reactor.
Radioactive water is showering down on them as they struggle to turn a large valve. They are becoming increasingly weak and Toptunov frequently has to stop in order to vomit. Akimov’s skin will turn black and he will die in hospital on May 11. He told a colleague his conscience hurt him more than the pain. Toptunov will die three days later. The bravest people at Chernobyl were those most likely to die.
On Sunday, April 27, the city of Pripyat was finally evacuated. The population were told that ‘an unsatisfactory radioactive situation has occurred’ and to leave their pets and take enough food and clothing for three days. They never returned.
In total, almost 350,000 people were moved out of the Chernobyl area.
The outside world knew nothing about the disaster until Monday, April 28, when Cliff Robinson, a Swedish chemist at a nuclear power plant near Stockholm, passed through a radiation detector on his way to clean his teeth at the end of a shift. To his surprise, an alarm went off. Radiation was found on his and other workers’ shoes.
When it was discovered that a cloud of radioactive gas was drifting west across Scandinavia, suspicion immediately fell on the Soviet Union as the source of the contamination.
Later that day, the accident at Chernobyl was the seventh story on the Soviet state television news.
Eventually, the radioactive cloud spread north over the whole of Scandinavia and into Germany and Czechoslovakia, causing toxic rain to fall. Pharmacies in Demark sold out of potassium iodide tablets.
A week after the disaster, radioactive particles in rain fell on North Wales. For more than a quarter of a century, all Welsh lamb produced for human consumption was monitored for radioactivity.
Today, 33 years on, there is still a 30km exclusion zone around the Chernobyl site because radiation levels in the soil remain high. But this so-called ‘dead zone’ is now open to tourists, who visit on day passes.
Nature has flourished and there is an abundance of wildlife. It is illegal to live in the zone but up to 150 people, mainly elderly subsistence farmers, still do. In recent years, a few Ukrainian families — some of them fleeing the Crimean conflict — have moved to live in homes abandoned just outside the exclusion zone.
Buildings in the abandoned city of Pripyat have been stripped of valuable metal by looters. Among the crumbling homes, schools, shops and offices lie toys, shoes and gas masks on the ground.
A total of 31 firemen and workers died at Chernobyl. So radioactive were some of their bodies, they were buried in lead coffins with the lids welded shut.
A World Health Organisation report estimated that, of the 600,000 people across the Soviet Union exposed to the highest levels of radiation, 4,000 would eventually die.
It has been claimed that if all four nuclear reactors at Chernobyl had been damaged by the explosion, most of life on Earth would have been wiped out.
- Chernobyl begins on Sky Atlantic on Tuesday, May 7, at 9pm.
