Treatment of Fission Product Solutions in Cs$sup 137$ Separation; TRAITEMENT DES SOLUTIONS DE PRODUITS DE FISSION SEPARATION DU CESIUM-137
Presented at "Conference sur l'emploi des radioisotopes dans les sciences physiques et dans l'industrie organisee par l'Agence Internationale de l'Energie Atomique, Copenhague, Septembre 6-17, 1960." (RICC/4) For the industrial recovery of Cs/sup 137/ from solutions of fission products, the analytical method for determination of cesium by dipicrylamine was used, adapting it to an industrial scale and to the high level of the activities encountered. The process makes it possible both to isolate cesium as a chloride and to recover the reagent in one and the same operation. The effect of radiation on dipicrylamine and its compounds was studied, this effect proving to be practically nil for solid compounds and negligible for their solutions. The entrainment of cesium by ammonia ion was also studied. The advantages of the proposed process are outlined. By this process cesium can be recovered before certain fission products are eliminated.
