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 in Russia (vanadium, steels) are presented. The industrial technology for pure vanadium manufacturing is considered from the point of view of low activation material. The important consequences of gaseous forming elements present in vanadium on induced activity are highlighted. Results on the development of a few prototypes of low activation steels are given. The suggestion to use isotopically enriched materials for the most critical structures of reactor has been systematically considered, and conclusions are given. Some aspects of the recycling of structural materials are briefly discussed.
