Batch extraction and stripping tests with uranium and plutonium

  • 1. Oak Ridge National Lab., TN

Description

Batch extraction tests with 30% TBP and highly irradiated LWR fuel show that losses of both U and Pu to the aqueous raffinate can be well below 0.01% of the feed. Stripping of highly loaded TBP with dilute HNO3 resulted in equally good recoveries from the organic, but the distribution coefficient (DC) for Pu increased significantly after >99% had been stripped. With long contact time during extraction (very high radiation exposure) there was essentially no change in behavior. Stripping of Pu from TBP loaded with U to <20% of saturation was much less effective, a major fraction of the Pu having a DC of about 102. Aging the loaded organic before stripping increased the fraction of Pu that was more difficult to strip. 3 figures
