Did You Know?


Legasov breaks the news to Shcherbina that they will both be dead in five years. His prediction came true. Legasov hanged himself two years after the disaster and Shcherbina died in 1990, of undisclosed causes. See more »


Legasov tells Shcherbina that uranium 235 spontaneously emits neutrons because it has too many. Uranium 235 only emits neutrons when it splits. This mostly happens when the uranium 235 atom absorbs a neutron although it can happen in an extremely rare spontaneous fission event. Uranium 235 does spontaneously emit alpha particles which play no role in the fission process. See more »


Michail Gorbatchev: Comrade Shcherbina, I want you do to go Chernobyl. You take a look at the reactor, you personally, and you report directly back to me...
Boris Shcherbina: [speaking too soon] Wise decision, comrade general secretary.
Michail Gorbatchev: ...and take professor Legasov with you.
Boris Shcherbina: Eh, forgive me, comrade general secretary, but I...
Michail Gorbatchev: Do you know how a nuclear reactor works?
Boris Shcherbina: [beat] No.
Michail Gorbatchev: No. Well then, how will you know what you are looking at? Meeting adjourned.

Real life stories are most interesting and thrilling
14 May 2019 | by pkperaSee all my reviews

First episode was great, and this, second one even better. I see here 10 reviews. all with rating 10, and yes, it deserves it, absolutely.

I'm glad to see that HBO made something really good, after getting sick from all loud advertisement of their Game of Thrones, what I stopped to watch years ago.

As much I can see, the level of details is high, they recreated that environment very well. Looks almost like documentary. Acting, direction, dialogs ... all top level. And even pacing is superb - of course slow for some audience, but they probably were not attracted right at title.

Now something related with my memories from that time, and I was about 2000 km far from accident, related with anti-nuclear power talk by about half of reviewers here. I was not aware how bad was it, and that it could be much-much worse - assuming that it was not overdramatized . We had some warnings to not eat green vegetables, and that was approx all considering radiation spread to our area. About cause of explosion details came much later, in diverse versions. Years passed until was revealed that it was fatal experimenting, done very irresponsible by current staff. I don't think that there are some realistic chances that very similar happen in some Western (type) nuclear power plant. One of main reasons is that they have very massive dome, intended mostly for case of plane crash. Sowiet type reactors saved on it. Domes should survive similar reactor explosion - what was of course not nuclear one, rather explosion caused by created hydrogen .

What should worry us, normal people is rather attitude of people on power. Their disrespect of ordinary people, taking care only about own and own class interest, looking to ordinary people as some sub humans. And it is present everywhere, more-less. We can not say that it was something characteristic only for communistic regimes. Or some mid-east dictatorship. Events like it can be avoided when people in charge do it's job responsible, or even better - with moral. And being aware what is most important: good of many vs. submitting to boss, making some carrier and go higher in hierarchy ... Surely, that needs some courage, sometimes sacrifice. But that makes us humans. And that 3 men at end, they were it. We don't need super powers, we need people knowing and willing to engage their powers in something good for all as, for this planet, life on it.
