  • How technically feasible is the partitioning and transmutation of long-lived radiotoxic nuclides in the waste from reprocessed spent nuclear fuel?


Less stringent conditions would be required for the isolation and storage of spent nuclear fuel if long-lived radionuclides could be partitioned from the remainder of the waste. The removal of alpha-emitters, which are the main contributors to the release of heat in the waste, would allow for a denser form of storage. Long-lived fission products represent only a tiny fraction of the total radiotoxicity. However it was thought, on the basis of now obsolete data, that these could migrate relatively quickly out of a repository because of their chemical properties. A workshop was therefore held in Karlsruhe in October 1989, to discuss transmutation processes, target or fuel developments, minor actinide partitioning and transmutation strategies.
