U.S. nuclear fuel recycling takes two steps forward
Late last week saw two announcements from companies working to recycle used nuclear fuel on a commercial scale, providing welcome news to anyone hoping to see the United States move to unlock the hidden potential of the more than 94,000 metric tons of spent fuel stored at power plant sites around the country.

Aluminum oxide aerogel can be used as a backlighter target to provide a radiation source for diagnostics during ICF experiments. To demonstrate the feasibility of this type of target, it was necessary to cast thin pieces of aerogel for plasma emission studies of aluminum oxide. We were able to demonstrate density control over a range of 50-400 mg/cc, and, furthermore, cast the aerogel as a thin (0.6-0.7 mm), smooth monolith that did not require additional machining. The fabrication of these targets begins with a solution of aluminum chloride, ethanol, and water and is then catalyzed with propylene oxide to gel within molds to form the shape. Supercritical drying with carbon dioxide provides the dry aerogel. Various target densities were made by adjusting the relative amounts of starting materials and post treatment condition. The finished materials were characterized for density, pore size, and water content. Initial freestanding targets of 98 mg/cc have been fabricated and shot, and other similar targets of densities from 50-400 mg/cc have been fabricated for future experiments.
