I have added a link to Nuclear Waste News because I think that it is important for people to understand the issues associated with the disposal of nuclear fission waste products.

The nuclear option is being seriously reconsidered in light of global warming. We can not address the issue of nuclear waste safely by burying it. We must implement the necessary technology to eliminate long term nuclear waste. If this is done then nuclear fission can contribute to our energy needs safely.

If we implement a combination of nuclear fast flux nuclear breeder reactors, along with on-site reprocessing, along with fast-flux actinide burning reactors, we can safely extract 60-70 times as much energy from uranium ore as we do presently while at the same time eliminating the long term nuclear waste stream and the threat of plutonium being used to build bombs.

Reprocessing that separates out all the actinides from the waste together allows them to be re-used as fuel without ever isolating plutonium-239, and thus provides a fuel cycle which provides no bomb building materials. Additionally, since all processing is done on site, the need to transport high level actinides is eliminates. Only fission products remain, and they are very hot initially but decay rapidly. They represent a storage liability of 300-500 years, far shorter than the 50,000 years or more for plutonium.
