Even if we ignore the black swan events (which each time they happen we hear how it could never happen again, etc), nuclear has a long, sordid history of massive schedule, cost and operational expense overruns. Energy companies stopped building nuclear not because of those damn eco warriors, but because they had been jaded by project after project that cost multiples (or magnitudes) of estimates. It just isn't cost effective. There are some places where nuclear makes more sense -- on a spacecraft, for instance -- but in most worldly cases it is no longer a competitive option.
