I don't know a lot about it but I think it was just an old, cheaply constructed powerplant. It was neglected and grossly underfunded because the government was largely corrupt. Officials filled their own pockets and the pockets of their friends rather than maintain utilities. Predictably, there was a disaster.
But don't worry, that could never happen here in Canada. Well, alright, we had the Walkerton thing but our neglected nuke plants haven't melted down... yet. Yes, everything is fine, nuclear power is perfectly safe, just hang on to these potasium iodine pills just for fun.lol!
I feel a little light headed... maybe you should drive...
