Abstract

This study is aimed at determining the acceptability of each natural element as a constituent for fusion reactor materials, for the purpose of limiting the long- lived radioactivity, so that the material could be recycled, or disposed of by near surface burial. The availability of a new and complete activation cross section library, REAC-ECN, allows to perform activation calculations for all the stable elements. The results show that there is little incentive in developing elementally tailored steels for the purpose of recycling. More interesting and feasible is the development of a steel with an optimized composition that would allow to reach SLB (shallow land burial) conditions also for the first wall. A better knowledge is still needed in some fields: the level of a few critical impurities in raw materials and in the steels produced with them, the acceptable concentration of long-lived nuclei in SLB, and the accuracy of the cross sections for some important activation reactions.
