Abstract
Quality control analyses of Pu based nuclear fuels for trace metallic content by the DC-Arc-AES technique, produce a large amount of solid analytical waste containing Pu, U and Ag. Through the present study, an attempt was made to separate uranium from the bulk of the analytical waste using HNO3 leaching. Systematic studies have been carried out to optimize various parameters, such as acid molarity, contact time, and batch size, required to remove uranium preferentially from the solid waste leaving behind Pu and other impurities. The concentrations of U, Pu, Ag and other impurities during this exercise were intermittantly determined using ICP-AES.
