Abstract
Using NET-type neutron flux distributions estimates are made of the production rates of 10Be and 14C in the typical blanket materials 316-stainless steel, carbon, lithium and beryllium. As well as production rates arising from direct neutron interactions, all possible nuclear pathways are identified which could produce 14C and 10Be from charged particle interactions in the initially-loaded materials, the charged particles themselves arising from (n,p), (n,α), (n,d) and (n,t) interactions in these materials. Estimates have also been made of 14C and 10Be production which could arise from both neutron and charged particle interactions in transmuted (i.e. secondary) materials in the blanket. Comparisons made with production rates of 55Fe, 57Co, 58Co and 60Co show that 10Be and 14C production rates are significantly less than 1% and would not contribute significantly to the materials handling and safety problems of a commercial NET-type controlled thermonuclear reactor.
