It is not alone in this, for nuclear operations around the world have poor records on public accountability. The three biggest nuclear accidents before this – Chernobyl, the 1957 Windscale Fire and a nuclear waste explosion in Chelyabinsk, Russia – were all initially kept secret.
The Chelyabinsk explosion (also known as Kyshtym and I\’ve driven through the affected area) was from the early Soviet attempts at bomb making. Similarly, Windscale was deliberately designed to maximise the plutonium produced, again for bomb making purposes.
It\’s ever so slightly naughty to point to failures of bomb making plants as failures of civilian nuclear power.
