Abstract

The operating conditions in fusion power reactors will be extremely severe. Low activation materials which can be exposed to neutron fluences of the expected order of magnitude (200 dpa) without drastic changes in their properties, are not yet available. The existing alloys which are currently considered for further development do not comply with the requirements for low activation materials. The other main issues to be considered in the choice of reactor materials include radiation damage, thermal stresses and fatigue during the lifetime of the reactor. For the DEMO reactor, new materials have to be developed, especially for the first wall and blanket structures.
