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.

Recent R&D of an edge Thomson scattering system for ITER (International Thermonuclear Experimental Reactor) are reviewed. We have designed a diagnostic laser system (5 J, 100 Hz) based on JT-60U diagnostic laser design (7.46J, 50Hz). New laser oscillator has been developed, and prototype amplifier has been assembled for ITER. Regarding a collection optics in a port plug, improvement of previous design has been carrying out. As for spectrometers, a new technique of Fourier transform spectrometer for Thomson scattering has been considered in addition to a filter polychromator.
