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 two-fluid theoretical model of heat transport in tokamaks is developed based on microinstabilities. A τE scaling of the form has been determined from this transport model. The theoretical τE scaling is used to determine the smallest size tokamak fusion reactor for two cases, ignition and Q = 5 steady state. Parameters are in good agreement with Tokamak Ignition/Burn Experimental Reactor II designs based on empirical Kaye-Goldston τE scaling.
