Captions indicate that scenes take place at the "Byelorussian Institute for Nuclear Energy" and "Byelorussian Communist Party Headquarters", both in Minsk. During the Soviet era "Byelorussia" was then the common English spelling of what later became the independent nation of Belarus, of which Minsk is the capital city. See more »


There was at no stage the risk of a multi-megaton thermonuclear explosion during the Chernobyl disaster. There was no risk of a nuclear explosion of any kind, not even in the low kiloton range. The actual risk posed by the core melting through to the water-filled bubbler pools below was that of a "conventional" steam explosion. It would have been powerful, it might have impacted the other reactor blocks and made the disaster somewhat more severe, but it doesn't even compare to any kind of nuclear yield. A nuclear yield would have made things several orders of magnitude worse and there was not even a theoretical chance of that happening. See more »


Valery Legasov: An RBMK reactor uses uranium 235 as fuel.

Best show on TV right now!
14 May 2019 | by deltaopSee all my reviews

There are no two ways about it, Chernobyl is the best show on TV right now. Just two episodes in, and it is perfect in its storyboarding and acting.

A strong premise brimming with sustained tension along with powerful performances by Jared Harris, Stellan Skarsgård, and Emily Watson, draw you in and don't let you go until the very end.

Fellow Game of Thrones disappointees, drown your sorrows with this one!
