Doses to man from repositories with fusion waste from the ITER TAC-4 concept. Final report

Doses to man from repositories with fusion waste have been calculated for the ITER TAC-4 concept. The calculations were performed for a swedish scenario with a deep geological repository situated under a land area and a shallow repository situated under a land area. Activation products (Ni-59, Ni-63 and Nb-91) and tritium in waste from the divertor, blanket and vacuum vessel were considered in the study. The waste in the repositories will for this scenario give the total maximum individual dose equivalent rate 3x10-6 Sv/year and the total maximum collective dose equivalent 10-5 manSv/year with Ni-63 as nuclide of greatest importance for the dose equivalent rates in both cases. 9 refs, 5 tabs
