The emulsion Which results from Di-n-butylphosphoric scid (HDBP) and zirconium (HDBZr emulsion) was studied on the formation ratio to the emulsion of nonsoluble fissioproduct residues (nonsoluble residues emulsion) in the condecontamination cyclewithoutsolvent washing. HDBP-Zr emulsion was found three times of nonsoluble residues emsion by one week's operation of the codecontamination cycle with the spent nuclear fl burnt to 28,000 MWd/MTU and cooled 1,000 days. In this codecontamination cycle, 1 HDBP was salted out at the aqueous/organic interface as HDBP-Zr emulsion, and10% HDBP dissolved in the recycling solvent stream as HDBP-U complex. It was found that HP-Zr emulsion accelerates the volume growth of nonsoluble residues emulsion by the elsifying effect.

The extraction processes on repro-cessing Japanese Experimental Fast Reactor (JEFR, named as JOYO) fuelhave been studied with an unirrad-iated uranium and plutonium,suppo-sing that the JEFR fuel will betreated with no modification of thefacilities and the operation condi-tions except the solvent employedand the dilution of the fuel in the PNC Purex plant under constructionfor the exclusive use of lightwater reactor fuels. The applicability of the extractionfacilities in PNC plant to theextraction of JEFR fuel was verified,concerning the recoveries of uraniumand plutonium in the co-decontamina-tion cycle,even in the case that thesolvent was changed to 10% TBP from 30% TBP employed in a light waterreactor fuel reprocessing・Also,theValidity of 30% TBP system on thepartition cycle of uranium and plut-onium was confirmed with regard tostripping plutonium.
