Just like they said all previous times.
First took them decades to 'discover' there had been 'accidents'. Then they 'just let it sit' for another 7 years, before being forced to do 'something' because the building was planned to be demolished. Then they try to jungle-rig together some contraptions that might scoop out the spill without too much cost Then it takes them another 5 years to accidentaly stumble upon the spill not being so contained as they 'hoped'. But hey, trust them. This time they promise its all safe and stable. Once again.
This is the same comedy capers fly by night operations we see time and time again in each human endeavour. Yet somehow, the nuclear lobby wants us to believe they are exempt from human failty, despite being disproven time and time again.
Nuclear power might be great, but humankind just can't handle the responsabilities.
