Surplus plutonium for power reactor fuel: What’s on offer
The Department of Energy has a plan for private companies to “dispose of surplus plutonium”—about 19.7 metric tons in both oxide and metal forms—by “making the materials available for advanced nuclear technologies.” A Surplus Plutonium Utilization Program request for applications (RFA) issued October 21 describes the plutonium on offer, and the “thresholds” prospective applicants must meet.

A model is described which permits conservative homogenization of a random distribution of low-enriched UO2 pellets in a low-enriched UO2 powder and water mixture. The model is used with a Monte Carlo criticality code to demonstrate the criticality safety of General Electric Model BU-5 bulk uranium shipping containers which are used for the transportation of unirradiated uranium compounds in the form of powder or pellets, moderated to any degree and enriched to a maximum of 4 wt% in the 235U isotope.
