Abstract
Dihydroxyurea (DHU) is a new salt-free reducing agent applied for the separation of Pu and Np from U in spent fuel reprocessing. This paper reports on the γ-ray radiolysis of DHU in HNO3 and its radiolytic products. DHU is relatively stable against radiation at the dose supposed to be absorbed in the separation of Pu and Np from U. The main radiolytic products are H2, CO2, N2O and NH 4 + . The volume fraction of H2 increases with the dose, but decreases with increasing HNO3 concentration. The quantity of CO2, N2O and NH 4 + increases with the HNO3 concentration and the dose.
