Take a look at this graph: Nuclear Electricity Production. It's quite easy to spot 1986 on this graph (Chernobyl). That's where the trend of acceleration in nuclear power growth has reversed into deceleration. No such reversal has occured in demand for electric power, of course. The shortfall has been largely picked up by coal.
The number of people that have been killed by air pollution from coal as an indirect result of the nuclear stagnation after the Chernobyl accident is well into the millions.
