Comparison of the performance of solvent wash reagents used for the primary cleanup of degraded PUREX solvent

Comparison of the performance of solvent wash reagents used for the primary cleanup of degraded... AbstractThe effectiveness of the solvent wash reagents such as sodium carbonate and hydrazine carbonate were compared using the lean solvent obtained during reprocessing of high plutonium content fast reactor spent nuclear fuel. The concentrations of the reagents were optimized based on the removal of retained metal ions from the lean solvent and 1.5 M hydrazine carbonate was found to be optimal and superior to sodium carbonate to be adopted as the reagent for primary cleanup of the spent solvent. Both the reagents were found to possess excellent room temperature stability and their performance was not affected upon gamma irradiation which was assessed in terms of capacity to remove di-butyl phosphate from degraded TBP/n-DD system. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Radiochimica Acta de Gruyter
