Abstract

Research in the field of low-activity structural materials for the first wall and blanket of nuclear fusion reactors has assumed much importance in the last few years. In this report the effects of the presence of low concentrations of unintended impurities among the basic components of low activation materials on their long term activation and dose rate levels have been investigated. A new library of neutron cross-sections has been generated with the THRES-F code for all those elements that are not traditional components of structural materials. The contribution of 1 ppm of each possible impurity element to the long term activity and gamma dose rate of a structural material has subsequently been determined with the aid of a modified version of the ORIGEN code.
