fission prcducts from solvents used in fuel element processing were studied. Eight Amsco-TBP solutions were equilibrated with water. The resulting water-saturated phases were separated and irradiated. Results showed that the presence of water enhanced acid production in up to 30% TBP and depressed it above 30%. Irradiation of nitric acid-equilibrated TBP-Amsco phases at two different temperatures indicated that radiolysis damage to nitric acid was temperature dependent and that G(MBP) and G(DBP) values were independent of nitric acid concentration. Irradiation of Amsco and Solvesso-100 showed that gas formation in Solvesso-100 was 1/7 that of Amsco, but radiolytic induced carbon- carbon unsaturation was twice that of Amsco. DSBPP-Solvesso-100 was found to be 4 times as stable to acid production as TBP-Amsco. Irradiation of 1 M TBP-Amsco solutions, which were contacted with 0.3, 1, or 2 M nitric acid, indicated that nitric acid suffered preferential radiation damage. Bcth increasing dose and increasing acid concentration increased the rate of DBP to MPB conversion. Acitvated charcoal, used for decontamination of fission product-contuining TBP- Amsco phases, produced decontamination factors (DF) for Ru which varied from 7 to 132, and for Zr and Nb DF values varied from 9.4 to 345. Simple centrifugation of organic materials gave DF values for Ru and Zr of 5.36 and 7.18; centrifugation plus Fe(OH)/aub 3/ carrier gave values of 14.60 and 63.60; centrifugation plus Al(OH)/sub 3/ carrier gave 70.2 and 59.60 as decontamination fuctors. Electrocoagulation was studied as a methcd of effecting coagulation of finely divided radioactive material. The molar ratio TBP/H/sub 2/O was determimed to vary from 6.86 to 1.58, as the molar TBP concentration in Annsco varied from 0.151 to 2.260. The molar ratio of TBP-HNO/sub 3/ varied from 2.38 to 3.01 as molar concentration in Amsco varied from 0.376 to 1.505. (M.C.G.)
