Abstract

The production of actinide reference materials in the European Community depends in those cases in which electromagnetically enriched material is required on the supply by the U.S.A. (DOE/ORNL). A study carried out by CBNM is based on the needs for actinide reference materials in the EC as determined by a separate inquiry in 1977 and examines the conditions for the installation of an electromagnetic separation facility of appropriate size in the EC. From a compilation of all information about the production, chemical purification and isotopic enrichment of all actinide nuclides needed in the EC those cases have been assessed for which the application of electromagnetic isotope separation is at present unavoidable (but feasible with the glove box technique). Base materials for this separation process are readily available within the EC with the exception of 244-Pu. The production of 244-Pu was experimentally studied and extrapolated to production scale. The use of this isotope as a spike material in mass spectrometric Pu determinations is shown to be uneconomic. An electromagnetic separator adapted in capacity to the EC needs was designed. Special containments and facilities for handling the radioactive actinide elements are proposed. From the cost price of this facility and operational experience of a few EC laboratories the total running costs and the specific product costs for the EC needs are calculated.
