Cost of Major Nuclear Accidents per Kilowatt Hour
Let's see… The cost of the Fukushima mishap is estimated at $130 billion. There have been around 25 years between major accidents. (Kyshtym was 28½ years before Chernobyl.) The world's nuclear power plants can generate 374,958 MW of electric power and do so 79.3% of the time. Put it all together and we get an average cost of major nuclear accidents (assuming Fukushima is typical) of ⅕¢ per kilowatt hour.
