Transmutation analysis of realistic low-activation steels for magnetic fusion reactors and IFMIF

A comprehensive transmutation study has been performed for steels considered in the selection of structural materials for magnetic and inertial fusion reactors for the international fusion materials irradiation facility (IFMIF) neutron irradiation environment, as well as in the international thermonuclear experimental reactor (ITER) and a fusion demonstration reactor (DEMO) for comparison purposes. An element-by-element transmutation approach is used in the study, addressing the generation of: (1) H and He and (2) solid transmutants. The IEAF-2001 activation library and the activation code ACAB were applied in the IFMIF transmutation analysis, after proving the applicability of ACAB for transmutation calculations in intermediate energy systems.
