Spent Nuclear Fuel is Anything But Waste

Posted February 21, 2011 10:42 AM

From e! Science News:

Failure to pursue a program for recycling spent nuclear fuel has put the U.S. far behind other countries and represents a missed opportunity to enhance the nation's energy security and influence other countries, the former chairman of the Nuclear Regulatory Commission said Sunday. Dale Klein, Ph.D., Associate Vice Chancellor for Research at the University of Texas System, said largely unfounded concerns and "long-held myths" about the reprocessing of spent fuel have prevented the U.S. from tapping into an extremely valuable resource.

Re: Spent Nuclear Fuel is Anything But Waste

This is one of the most important problems to solve for our energy supply of the coming centuries.

The articles mentions the 95% unburnt uranium in used nuclear fuel.

(This can be made much better with the CANDU -type reactors).

But what is more important is a fact about the long-living radioactive waste that is in these used fuel rods.

This waste is composed of short lived fission products (2-5000 years needed safe deposition) and long lasting highly active trans-uranium elements (200 to 500,000years needed safe deposition).

So the discussion about a final depository may be much easier if good quality reprocessing and storage (may be for decades or centuries) of the separated fractions would be initiated.

The debates about Yucca-mountain in the US and Gorleben in Germany (and other sites) would vanish into nearly nothing if only this new direction would be started.

Help to distribute this and mother Earth will reward you.
