| Popis: | The extraction of U, Pu and Am from HNO 3 solutions using tri-n-butyl phosphate (TBP), a mixture of 0.2M CMPO + 1.2M TOP and Cyanex-923 in dodecane has been carried out. The mixed oxide (MOX) fuel rejected during fabrication, termed as dirty rejected oxide (DRO) sludge was dissolved in HNO 3 and a procedure has been developed to recover U, Pu and Am from this waste using the above extractants. Also, a procedure has been developed to recover almost quantitatively the U, Pu and Am content from one of the difficult analytical wastes generated after the Davies and Gray analysis of U, in presence of Pu containing H 3 PO 4 , H 2 SO 4 , and HNO 3 , by using a mixture of 30% Cyanex-923 + 20% TBP in dodecane. |
