Abstract

In the frame of the 1991 French national law on waste management , the CEA has launched research and development studies on the separation of some long-lived radionuclides (LLRNs) from high active waste issuing from the reprocessing of nuclear spent fuel. Six LLRNs are the targets of these studies; they are: (i) the minor actinides, neptunium, americium and curium, (ii) the fission products, technetium, iodine and cesium. The reference strategy for separating these elements from the spent fuel is based on an adaptation of the PUREX process for Np, Tc and I separation , and on the development of new liquid-liquid solvent extraction processes for Am, Cm and Cs. The scientific feasibility (i.e. the concept validation) of the processes developed has been demonstrated on genuine radioactive solutions by the end of 2001 [1,2], and the CEA has selected a route for the demonstration of the long-lived radionuclides separation technological feasibility to be done before 2006. This paper deals with the current status and future R&D program in France on the separation of these LLRNs.
