Abstract Plutonium oxalate supernatant requires a treatment step for further recovery of the residual Pu. As ion present in solution poses problems during Pu, it needs to be destroyed. In work, Mn 2+ based catalytic destruction was studied detail, as could minimize generation secondary radioactive waste compared conventional process. The effect various parameters, namely concentrations HNO 3 , catalyst, oxalic acid and metal has been studied. Moreover, robustness method along with kinetics reaction investigated. process also demonstrated Pu generated from CORAL at 1 L scale.
