In spite of theoretical safety concerns, in practise in the West nuclear power has been several orders of magnitude safer than coal, which has killed plenty of people.
In fact, nuclear plants are so safe that their safety may have been counterproductive --- it can argued that for every life saved in improving the safety of nuclear plants several lives have been lost in constructing those super-safe plants. Can't present a graph here but obviously at some stage the rising fatal accident rate associated with increased investments in constructing safe buildings will intersect with the declining fatal accident rate resulting from the added safety.
Not easy to explain to the general public, though. The individual deaths of 100 construction workers employed in building nuclear plants is not headline news. But if a sparrow falls within a radius of ten miles of an operating nuclear power station Greenpeace and co. will start turning on the waterworks ....
