Activation of beryllium in a fusion power plant

The activation and transmutation behaviour of beryllium in the first wall o i a Fusion power plant has been studied using the up-to-date inventory code FISPACT-97. Assuming detritiation, the activity and dose rate will be dete rmined by the impurities initially present in the material. The possible in fluences of sequential charged particle reactions and of trace amounts of T h and U as fissionable actinides are examined but found unlikely to be impo rtant. Beryllium appears to offer the prospect of reuse in further plant fo llowing minimal processing after decay storage for about 50 yr. (C) 1998 UK AEA. Published by Elsevier Science B.V.
