| Abstract: | This paper reports the effect of HNO3 on radiation stability and radiolysis product of N,N-Diethylhydroxylamine (DEHA), which is used as a reducer in the reprocessing of spent fuel. Results show that with the addition of HNO3, radiation stability of DEHA is weakened obviously, the volume fraction of H2, CH4 and C2H4 decreases but the concentration of CH3COOH increases. As to 1.0 and 2.0 M HNO3, the concentration of CH3CHO increases, but it decreases when HNO3 is 3.0 M. |
