Comparison of transmutation and activation effects in five ferritic alloys and aisi 316 stainless steel in a fusion neutron spectrum

Transmutation and activation characteristics are presented for alloys FV448, EM12, 1.4914, HT-9, the Japanese alloy E5 and 316 stainless steel as a reference material. The alloys were assumed to be subjected to a first wall neutron power loading of 7 MWm−2 continuously for 2.5 years in the spectrum of the Culham Conceptual Tokamak Reactor IIA. The computations used a modified ORIGEN code and the neutron cross section data library UKCTRIIIA.
