I watched it and greatly enjoyed it - so my spouse bought me "Midnight in Chernobyl" by Adam Higgenbotham. What an amazing and terrifying story - I couldn't put it down and read it all in just two days.
His book offers far more detail of the events, and is even far more frightening than the movie on HBO.
There were 16 more RBMK reactors in the Soviet Union, all of them with the same safety flaw, that the Scram AZ5 button might accidentally trigger the reactor to explode and melt down, like Reactor IV did, in Chernobyl.
Also, reactor IV shared a common, open, un doored or gated, or secured cement passageway with reactors I, II, and III at Chernobyl, which meant there were some serious concerns whether they might be brought into the same situation - what if they had tried to use the Scram buttons on reactors I, II, or III ?
I never realized how the catastrophe at Chernobyl led so directly to the fall of the Soviet Union - Premiere Gorbachev's words, not mine.
The incredible bravery of the Ukranian/Russian Soviet citizenry in dealing with and finally solving the mess at Chernobyl is amazing, distressing, heart breaking and very sad - I wonder if they had any idea that their heroic efforts were due to the state they held in such high regard.
I agree the HBO miniseries is superb - great cast, great story telling, and informative about how the people actullay led their lives in the Soviet Union.
The sets of the towns didn't really stand out as fancy or lavish in the video, but by Soviet standards, the towns were very nice, indeed, exceptional to the folks who actually lived in them....compared to most Soviet citizens lodgings.
