methods of powder production from uranium alloys have been investigated within the US-RERTR program. These processes are grinding, cryogenic milling, and hydride-dehydride. In addition, a gas atomization process was investigated using gold as a surrogate for uranium. Grinding was found to be inefficient and introduced impurities into the fuel.

Cryogenic treatment changes the entire structure of a metal, not just surface. So the benefits are not lost as a result of further processing, such as grinding. Because this process works to treat austenitic steel that is retained in a component, it is not effective in treating ferritic and austenitic steels .
