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 to describe an ion-electron-beam fluid equilibrium state is presented. The effect of the centrifugal force of beam ions on the plasma pressure profile is considered. From the toroidal force balance, it is possible to calculate the temperature and density for both ions and electrons. A preliminary calculation result of the plasma pressure profile in the three-fluid system is presented.
