PROSPECT OF DEVELOPMENT AND MANUFACTURING OF LOW-ACTIVATION METALLIC MATERIALS FOR FUSION-REACTOR

A study of the information generation on the subject of LAM is given. Some results on the development of low activation metallic materials i n Russia (vanadium, steels) are presented. The industrial technology f or pure vanadium manufacturing is considered from the point of view of low activation material. The important consequences of gaseous formin g elements present in vanadium on induced activity are highlighted. Re sults on the development of a few prototypes of low activation steels are given. The suggestion to use isotopically enriched materials for t he most critical structures of reactor has been systematically conside red, and conclusions are given. Some aspects of the recycling of struc tural materials are briefly discussed.
