Very unwise move. Japan would be much better off using Negawatts than Megawatts.
It should honor it's technological and protocolar society by managing energy usage, investing in energy savings, managing movements and ressource allocations so as to maximize efficiency before it even starts producing more energy.
Nuclear energy has proven itself to be dangerous, to cause accidents, to spill radioactivity, to leave dangerous radioactive waste and to bring the risk of proliferation. It is definitely not the route to take.

To this very day, I can't believe what has happened to Japan. In my eyes, held to highest esteem as our technological twin (USA's)....but bure aucrats ignored what I hope China will not ignor. In the 1970's several warnings were issued to the Japan's government about a specific and potential tsunami effects concerning cooling pumps for the four reactors. Further, that the calculated designs for abutments needed to addess tidal surges fell several feet short for quakes  along the coast of the Fukushima area. Nuclear power, in terms of safety, is entering a period somewhere between childhood and adolescence as did the automobile when the manufacturerers met up with the likes of Ralph Nader. China! do not dismiss the Thorium stream possibilities, do not use graphite or uncontained (without reinforced dome) reactors! learn from the French and build them all the same! the world will be watching! Don't mess up,  and offer assistance to your old enemy, The Rising Sun. Think of it as a "Marshal plan"....

As bad as Nuclear can be I can't see any other alternative energy source to provide a reliable base load for a 1st world nation-------------- ------------
We have a single solar panel on our roof. With responsible u se of energy it's more then enough power for our house.If every building was equipped with it's own solar panel, and people were able to visually see and understand their power usage - we would have no problems supporting ourselves without destructive sources of energy!
Too bad Americans are close-minded glutto ns
