Processes are described for the recovery of cesium137 from Purex type, first cycle waste solutions which result from the solvent extraction reprocessing of reactor fuels. Flowsheets are presented for recovering cesium from neutralized wastes by coprecititation with zinc ferrocyanide or from acidic solution by precipitation with zinc ferricyanide or zinc cobalticyanide. Further processing converts the cesium to cesium chloride, a stable form suitable for use in high intensity gamma irradiation sources. Modification of the cesium recovery process enables isolation of other valuable products including rare earths, cerium-144, and strontium-90 activities. Experience at Hanford Atomic Products Operation in the use of similar procedures for rge to the ground is described. A comparison of objectives and gested for fission product recovery is made. The effect of recovering certain fission products, particularly longlived nuclides, from effluents on temporary or long term storage or disposal of the effluent is discussed. (auth)
