D2EHPA EXTRACTION RECOVERY OF NEPTUNIUM AND PLUTONIUM FROM PUREX ACID SLUDGE SOLUTIONS

摘要

A batch D2EHPA solvent extraction process for recovery of neptunium and plutonium values from Purex Acid Sludge solution has been developed. This process recovers 95 to 98% of both actinides in a small volume (concentration factor of about 9000) of product solution and purifies them from essentially all contaminants except for small amounts of iron and uranium.
