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.
