Separation of the minor actinides: the DIAMEX-SANEX concept

Abstract

International audienceThis paper deals with the recent advances concerning the development of the DIAMEX and SANEX processes for the separation of minor actinides (americium and curium) from the raffinates produced by the PUREX process. The DIAMEX process is at the more advanced stage of development with a reference molecule and reference flowsheet well validated through numerous pilot tests. Concerning the SANEX process, the scientific feasibility of two of the three explored routes is now established and the last one is planned to be demonstrated in 2001 summer. So, by the end of 2001, the CEA will be able to select the best route for the demonstration of the minor actinides separation technological feasibility before 2006
