It is very tempting to watch this and just point the finger at good ol communism. Problem is power (in the form of people) is always infinitely corruptible...in communism through party prestige and influence, in capitalism through filthy lucre. Were it not for little luck, and the moral courage and integrity of Sir John Cockcroft, Windscale (Sellafield) could have ended up as bad...with the same sort of consequences for Northern England. And there was no shortage of misinformation peddling by the Government of the day to boot. You might ponder why the name has been changed as well.
You can draw your own conclusions as to how we might wish to build and regulate nuclear power stations in the future, as we seem hell bent on going down that route.
PS
Oh yeah...and much of this "abuse of power/privilege" type behavior is present in Fukishima as well.
Most of this is easily found online in the form of official reports with little effort.
