Integrative device and process of oxidization, degassing, acidity adjustment of 1BP from APOR process

• We designed an integrative device and process.
• The utilization efficiency of N2O4 is increased significantly.
• Our work results in considerable simplification of the device.
• Process parameters are determined by experiments.

Device and process of oxidization, degassing, acidity adjustment of 1BP (The Pu production feed from U/Pu separation section) from APOR process (Advanced Purex Process based on Organic Reductants) were improved through rational design and experiments. The device was simplified and the process parameters, such as feed position and flow ratio, were determined by experiments. Based on this new device and process, the reductants N,N-dimethylhydroxylamine (DMHAN) and methylhydrazine (MMH) in 1BP solution could be oxidized with much less N2O4 consumption.
