The yields of the decomposition products of TBP as the result of ..cap alpha..- and ..gamma..-radiolysis in the two-phase system 30% TBP in n-paraffin-3.0 moles/liter HNO/sub 3/ in the presence of Pu (sup/IV/) (10/sup -3/-10/sup -1/ mole/liter) and U(sup/VI/) (0.01-0.3 mole/liter) are determined by the methods of potentiometry, spectrophotometry, and chromatography. The yields of the formation of complexes of Pu (sup/IV/) with dibutylphosphoric acid (DBPA) and monobutylphosphoric acid (MBPA) are determined in the two-phase system studied. It is shown that with an increase of (Me) from 0.01 to 0.3 mole/liter, G, DBPA is increased from 1.9 to 3.0, and G, MBPA from 0.3 to 0.45 molecules /100 eV. The radiation gas, the composition, and the yields of gaseous radiolysis products of the organic phase are studied. The kinetics of the formation of DBPA in the presence of plutonium are considered. The velocity constants of the formation and decomposition of DBPA are determined. Based on the experimental data, the maximum decomposition yield of TBP is calculated, equal to approx.6.0 molecules/100 eV.
