Further studies on the recovery of fission products and uranium from Purex 1WW
The recovery of fission products from Hanford wastes has for some time been under investigation by various HAPO workers. Flowsheets for the recovery of cesium have been demonstrated, and one for the recovery of cerium is ready for full-level testing. Several tentative flowheets have also been proposed for the recovery of other fission products and of waste plutonium and uranium. The {open_quotes}Integral Flowsheet{close_quotes} developed by Chemical Research Operation is based primarily on the work of G.B. Barton. The present work is a continuation of that begun by Barton. The primary objective has been the recovery of long lived fission products, other than cesium, with particular emphasis on cerium-144 and strontium-90. Secondary objectives of importance include: (1) the isolation of uranium and plutonium into solutions suitable for recovery by recycle into appropriate Purex plant streams, and (2) gathering data that may be useful at some later date on the recovery of the remaining fission products (other than cerium and strontium) should these become valuable. Precipitation procedures were principally considered since idle plant facilities already exist which were designed for this type of process. It is also desirable that the processes developed be compatible with the already demonstrated cesium recovery flowsheet.
