Vaclav Smil, Czech-Canadian scientist and policy analyst. Professor Emeritus in the Faculty of Environment at the University of Manitoba in Canada: The age of commercial nuclear electricity generation began on 17 October 1956, when Queen Elizabeth II switched on Calder Hall, on the Cumberland coast of England. Sixty years is long enough to judge the technology, and I still cannot improve on my evaluation from the early 2000s: a “successful failure.” He says that we have to have better technology. The record for nuclear safety and production of electricity exceeds all other forms of generating electricity. For some, nuclear will never be safe or good enough.
