Study on groundwater radiolysis in deep underground radioactive waste repository

Yamaguchi, Makoto; Taguchi, Mitsumasa

Aqueous solutions of hydrogen peroxide were irradiated with helium ion beam to assess the effect of dissolved hydrogen which is presumed to be high concentration after anaerobic corrosion of metal canisters in deep geological repository of high level radioactive waste. While hydrogen peroxide concentration increased linearly with accumulated dose in argon-saturated solutions, it decreased in hydrogen-saturated solutions. Observed trends were successfully reproduced by homogeneous reaction model calculation.
