Blaine & Jerry:
Regarding the fission products, what Ed Sayre has to say about
their commercial value might be of interest. It's at
or < http://snipurl.com/15f0j9 >.
Quote: "The commercial value of over twenty million dollars a year for
each 1000 MW reactor is based on today's value for the rare metals in
products and the fissile metals to be recycled in fuel."

With regard to an ideal solution for spent nuclear fuel, I like
Jerry Cohen's suggestion:
"1. All nuclear fuel should be reprocessed and all fissile material
recovered for fuel fabrication or other useful purposes.
2. The raffinates including all unusable fission products should be
solidified by mixing it in concrete and emplaced and solidified in
3. The waste containing drums should be transported to the deepest
part of the ocean, and dropped to descend (>10 km.) to the ocean floor."
However, I would suggest a slightly different approach.
1. All spent nuclear fuel should be reprocessed and the fissile
material recovered for fuel fabrication.
2. The U-238 should also be recovered and used in breeder reactors
to convert it to a fissile material to recover all available energy
from the SNF.
3. The fission products (at least much of them) should be
incorporated into small glass or ceramic sources which could be
utilized for food irradiation facilities and agricultural produce irradiation.
I have worked at a food irradiation facility and know some of the
advantages of preserving food by irradiation. Agricultural produce
can be allowed to ripen on the trees and irradiated to allow shipping
with less spoilage. And the tree ripened flavor is much superior.
I regard all of the spent nuclear fuel as a valuable resource for
both energy and food preservation.
Of course, the public would have to overcome its radiophobia.
Just a thought.
