軽水炉コンクリート構造物の照射劣化予測手法の開発に係る研究計画
概要
A new research program of irradiation effects on LWR concrete member has been started since 2017. The previous research results indicate the reference level of neutron irradiation degradation on concrete should be set at 1 x 1019 n/cm2 which is one order of magnitude lower than the conventional reference level used in Japan. Several issues remain after the previous research and the objectives for clarifying the issues are set in the new project which is scheduled for five and half years. And international cooperation research between the US and Japan is also scheduled, in which synergy effects can be expected thanks to each country’s advantage. The research approaches are different between the US and Japan but the final goal of the research is the same, which means some bench mark approach can be performed.
