Advanced Head-End Processing of Spent Fuel: A Progress Report

摘要

Development efforts toward an advanced dry head end for the processing of U.S. spent fuel are underway and include previous experiences and lab scale experiments. The overall objective includes the separation of the hardware and cladding with the minimum degree of retained contamination and the early removal of the volatile (e.g. ~3H, Kr, Xe, I) and semi-volatile fission products (e.g. Cs, Ru, Tc, Mo) to simplify the subsequent processing scheme and to reduce the processing and waste disposal costs.
