Compounds of plutonium (IV) with alkylphosphates and phosphate in nuclear reprocessing
Description
The nature of Pu (IV)-alkylphosphates and phosphate formed, especially in the PUREX process chemical conditions, has been studied. (i) With HDBP, two solid compounds: Pu(DBP)3NO3,xH2O and Pu(DBP)4 have been identified in aqueous phase, and only one Pu(DBP)3NO3 in organic phase, (ii) With H2MBP one compound was found in aqueous phase: Pu(MBP)2,yH2O, while three compounds are formed with H3PO4, proposed formulas are PU(HPO4)(NO3)2, Pu(HPO4)2 and Pu2H(PO4)3. Solubility of some of these compounds were examined in the fuel reprocessing conditions, in aqueous or organic phase (30% TBP-diluent) excluding mixed biphasic systems. 9 refs
