While the events in Japan may give the anti-nuclear power fanatics an argument to use against future nuclear power, the fact is all the world’s nuclear power plants are based on very old technology. There are new innovations that solves a lot of the problems nuclear power may have (which have proven to be very few after all this time, it takes catastrophes for the plants to be a problem for the environment).
Thorium may be the answer nuclear power has needed all this time. Thorium based reactors are much smaller, are even portable. Do not have the problems that water based reactors have. And thorium as a fuel is more plentiful than uranium. We have enough in storage already to power the country for decades.
