PUREX PROCESS PERFORMANCE WITH SHORT-RESIDENCE CONTACTORS

PDF Version Also Available for Download.

Description

Recovery and purification were satisfactory in miniatarepilot-plant tests of the Purex first cycle with the solvent residing four seconds in each extraction stage. Decontamination factors for both zirconium-- niobium and ruthenium were greater than 10,000 with negligible crosscontamination of uranium and plutonium. The effects of the following on decontamination and plutonium partitioning were determined: irradiation level of the fuel, operating temperature, solvent saturation, accumulated exposure of the solvent, nitrous acid, and ferrous sulfamate versus U(IV) as a reductant for Pu(IV).
