Abstract
Four possible candidate materials for fusion reactor first wall have been analysed. A finite element code was used to determine the thermal stresses due to the temperature distribution of the DEMO reactor first wall for each material. The induced radioactivity was evaluated by simulating a 5-year exposure in DEMO. As far as the thermal behaviour is concerned, MANET and VA 64 have proved to be the most suitable materials but induced radioactivity in both of them is too high. Therefore, a low activation version of VA 64 has been studiedPubblicazioni consigliate
