Learning to love the dumb
Even though the problems in (Fukushima, Onagawa, Tokai...) Japan are ongoing, this disaster has already proven one thing: calculating nuclear-power-related risks exceeds real human capabilities.
It may be the sheer complexity of the task, or mainly the inherent corruption of the process due to economic and political expectations. In any case, wishful science has crippled Japan for the foreseeable future by wiping out quite a bit of its electricity generation, with a considerable human toll sure to follow.
(While other technologies lend themselves to speedy repair and rebuilding, NP does not, due to the radiation and subsequent risks and dangers.)
Basing future plans on obvious imponderables does not seem sane, especially given the alternatives. While the cost comparison between renewables and nuclear has too many flavors to satisfy, they are within reach, both financially and time-wise.
