本工作研究确保无盐Purex流程1B槽铀钚分离效果所需的二甲基羟胺-甲基肼的最低用量。通过单级反萃实验,考察了Pu(Ⅳ)还原反萃分配比随二甲基羟胺或甲基肼浓度的变化,选择理论上所需的二甲基羟胺和甲基肼的用量进行串级实验,以确定铀中去钚分离系数为1.2×104时还原剂的最低用量。
This work studied the minimum amount of dimethylhydroxylamine-methylhydrazine needed to ensure the separation of 1BU-Pu from the Purex process without salt. Through the single-stage stripping experiments, the change of Pu (Ⅳ) reduction stripping ratio with the concentration of dimethylhydroxylamine or methylhydrazine was investigated. The amount of dimethylhydroxylamine and methylhydrazine required in theory was selected for cascade Experiments to determine the uranium to plutonium separation factor of 1.2 × 104 when the minimum amount of reductant.
