Development of rig for systematic irradiation tests of fusion reactor materials in a fission reactor

Acquisition of systematic irradiation data are essential for understanding fundamental processes of irradiation effects and for establishment of a rel iable database for irradiation effects in fusion reactor materials. It will take several years with expensive several different irradiation rigs in a fission reactor irradiation. There, it will take a long time to carry out t he needed iterations between irradiation tests and evaluation and materials development. An irradiation rig was developed to carry out irradiation und er multiple temperatures and irradiation fluences. Irradiation tests of fus ion reactor materials were successfully carried out using the rig in Japan Materials Testing Reactor. (C) 1998 Elsevier Science B.V. All rights reserv ed.
