Right now spent US nuclear fuel is stored in cooling ponds onsite. There is a once through fuel cycle with no reprocessing. To quote the Wikipedia article: http://en.wikipedia.org/wiki/Nuclear_fuel_cycle#Reprocessing "The recovered uranium and plutonium can, if economic and institutional conditions permit, be recycled for use as nuclear fuel. This is currently not done for civilian spent nuclear fuel in the US." > The Gov wanted > the plutonium and did not want anyone else to have it. While the second part is certainly true, with breeder reactors at Hanford producing tons of plutonium, the US military certainly didn't need plutonium from commercial reactor cores to make bombs. Commercial reactors are poor breeders for plutonium. If you want to make bombs, it's much better to actually build a breeder reactor. > This is part of > the cost of nuclear power that does not show up in the cost of electric. > It is subsidized by the government. Reference please? Is this supposed subsidy, along with the sprialing regulatory costs, the reason that no more new commercial reactors have come online in over a decade: http://www.southernstudies.org/facingsouth/2007/08/tva-green-lights-watts-bar-2.asp Watts Bar in Tennesee took $8 billion and 23 years to come to fruition.

The NRC should safely restart the US commercial nuclear program: 1) They need to preapprove a simple safe reactor design. Test the hell out of it and approve it. Anyone who builds a plant with that design is streamlined to build. 2) Start reprocessing the spent nuclear fuel. You get 97% of the volume to put right back into the plants. 3) Take the final 3%, distill the hell out of the actinides (which are the longest term radioactive products), and take rest and stick it Yucca Mountain. BTW I know it sounds like I'm talking about an exclusively nuclear infrastructure. I really don't have a problem with solar, wind, or hydro. But at the end of the day each present significant limitations in their ability to provide wide scale power in a variety of different situations. Sometimes the sun don't shine, the wind don't blow, and the water don't flow. Use it where it's appropriate. But nuclear needs to be a part of the mix.
