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.

The H2 concentration was measured in the ventilated air of actual high-level liquid waste tanks of the Tokai reprocessing plant. It was compared with the value calculated from the parameters that were obtained using the simulated solution. Both values agreed satisfactorily within the limits of uncertainties of the parameters. This agreement showed that the catalytic H2 consumption reaction caused by Pd ions, which was found previously using the simulated solution, proceeds also in the actual solution. The measured “G(H2)” for the actual solution and the derived one using the parameters from the simulated solution were between 7×10−6 and 3×10−5.
