Hydrazine nitrate is being used as a stabilizer for U(IV) as well as Pu(III) during partitioning of Pu in PUREX process by scavenging the nitrous acid present along with nitric acid. As hydrazine hydrate as well as its salts have been successfully used for scrubbing of degradation products of TBP to aqueous phase, experiments were conducted to evaluate the consequence of hydrazine content duringPu partitioning. Itwas observed thathigher amount of hydrazine nitrate along with uranous nitrate in the partitioning streamof PUREX process leads to build up of DBP in aqueous phase and resulted in precipitation of Pu.
