STATUS OF SUBCONTRACT WORK ON EFFECTS OF RADIATION ON SOLVENT EXTRACTION PROCESSES

PDF Version Also Available for Download.

Description

The results of the Stanford Research Institute studies of the effects of radiation on solvent extraction processes are summarized, and a desirable direction for future work is indicated. Studies performed to date have shown that: (1) nearly all of the irradiation-induced increase in time required for TBP- -Amsco--aqueous phase separation is due to formation of a polymer, of unknown chemical structure; (2) uranium retention by the TBP-- Amsco phase during stripping operations is due approximately 65% to dibutyl phosphate and 20% to the polymer; (3) each 100 ev of energy absorbed forms abeut 0.5 hydrocarbon double bonds, with which fission ... continued below
