Abstract

From 1975 until 1982--within the framework of the CEC indirect action programme on management and storage of radioactive waste--the SCK/CEN has developed the ELEX process from laboratory scale experiments up to the construction of an integrated pilot installation. The ELEX process combines water electrolysis and catalytical isotope exchange for the separation of tritium from aqueous reprocessing effluents by isotope enrichment. Consequently, the pilot installation consists of two main parts: an 80 kW water electrolyser and a 10 cm diameter trickle bed exchange column. The feed rate of tritiated water amounts to 5 dm3.h"-1", containing up to 3.7 GBq.dm"-3" of tritium. This report describes the further development of the process during the second phase of the second programme. Three main items are reported: item"(i)" research work in the field of pretreatment of real reprocessing effluents, before feeding them to an ELEX installation; item"(ii)" demonstration of the technical feasibility of the ELEX process with simulated active effluent streams in the pilot installation; item"(iii)" a cost estimation for the ELEX installation, comprising the required investments and the annual operation costs.par
