Abstract

Taking into account the neutron activation (Bq/kWht) and the environmental impact in terms of Ingestion Toxic IT (m3 H2O/ kWht) of radioactive wastes coming from several low-activation structural material candidates for future nuclear fusion power reactors, the contribution of the material chemical composition elements and impurities to the overall radioactivity and IT has been assessed. The chemical impurities, also at very low concentrations, have been ascertained to give, in many cases, a considerable contribution to the radwastes environmental impact, as in the case of SiC/SiC fiber composites materials or low-activation martenstitic steels. The origin of impurities origin has been identified and efforts to use this information in the material production processes for nuclear fusion application are suggested.
