Radiolysis of water generates H gas. The radiolytic H production inevitably goes on when an aqueous solution contains radioactive nuclides such as plutonium nitrate solution in the nuclear fuel reprocessing. In order to obtain experimental data for the H safety assessment, we carried our measurements of H production from the aqueous plutonium nitrate solution at elevated temperatures. In this presentation, we will talk about experimental apparatus and results of a validation test of the apparatus using Co-60 gamma source.
