An experimental method was devised for the simultaneous irradiation and nitric acid equilibration of TBP - Amsco solutions. Solutions with three nominal nitric acid concentrations were irradiated with 1-Mev (nominal) electrons at three dose levels. Ceric dosimetry was used. Analytical procedures for the determination of dibutyl phosphate (DBP), monobutyl phosphate (MBP), and phosphoric acid (H/sub 3/PO/sub 4/) were reexamined and revised, and some improvement was attained. Work on analytical methods continues. The chemical changes produced in the irradiated solutions are characterized by high G values (molecules created or destroyed per 100 electron-volt energy input) for the disappearance of nitric acid and very low G values for the formation of phosphoric acid. G(--HNO/sub 3/) was in the rsnge 3.5 to 12.2; G(DBP) was in the rsnge 1.0 to 6.9; G(MBP) was in the range < 0.01 to 0.4. G(-HNO/sub 3/) and G(DBP) tended to increase with increasing acid concentration and to decrease with increasing dose. Gas samples were analyzed by mass spectrometry and relative yields of gaseous radiolytic products obtained. Four potential protective agents were screened. Three showed no marked effect (CS/sub 2/, latex, C/sub 7/H/sub 7/ I + I/sub 2/), while one(HBr) increased radiolytic yields. (auth)
