- Abstract
Dihydroxyurea (DHU) is a novel salt-free reductant used in the reprocessing of spent fuel. This paper reports on the radiolysis of DHU in water and its radiolytic products. The concentration reduction ratio of DHU after irradiation increases with the dose but decreases with increasing DHU concentration. The radiolytic by-products are H2, CO2 NH4+ and HNO2. The amount of H2, CO2 and NH4+ increases with DHU concentration, but that of HNO2 decreases with increasing DHU concentration. The quantity of CO2 and NH4+ increases with the dose. The radiation chemical yields of DHU destruction and radiolytic products are determined.
