Old reactor
Pushed beyond its designated lifetime
Closed for safety violations multiple times
Graphite core is full of cracks
Given permission to double allowable number of cracks
And just as a bonus:
In February 1997 there was concern that contaminated carbon dioxide gas from the plant had got into three road tankers and then entered the food chain via soft drinks and beers
Here’s a great documentary about the world’s first reactor meltdown, also a graphite core, which was in the North of England at Windscale. It was opened by the Queen in the guise of clean energy for the people, but was in fact secretly used to force the UK’s entry into the USA’s ‘nuclear weapons club’ by producing the plutonium for the first British Atomic and Hydrogen bombs. Short cuts imposed by the government, to meet a perceived deadline, led to the world’s first meltdown.
It’s pretty terrifying.
“Cool” spoiler : Last line in the film regarding the government of the day : “What a shower of bastards”
