| Los Alamos National Laboratory (LANL) has been tasked to produce 120 kg of plutonium as highly-purified PuO2 for the European Mixed Oxide (MOX) Lead Test Assembly (LTA) managed by Duke, COGEMA, and Stone & Webster (DCS). To meet technical requirements for PuO2 production, LANL recently demonstrated an ability to meet product quality specification using an aqueous polishing process. Polishing was required to remove undesirable quantities of gallium and other trace-metal impurities from the weapons-grade PuO2. The process flow sheet for PuO2 purification was based on aqueous recovery and included several unit operations of dissolution, ion exchange, oxalate precipitation, and calcination. Recent chemical and physical test results will be presented to show product quality and consistency in the production phase of this project. |
