The processing and downblending of uranium-233 for disposal has resumed at Oak Ridge National Laboratory, following a pause in operations due to the COVID-19 pandemic, the Department of Energy announced on October 20. Removal and disposition of the U-233 is one of the DOE Office of Environmental Management’s highest priorities at the site, as stated in its strategic vision released earlier this year.

The project is removing a significant risk by eliminating the inventory of highly enriched fissile material stored in Building 3019, the world’s oldest operating nuclear facility, according to the DOE. Employees, known as fissile material handlers, use shielded gloveboxes to dissolve U-233 into a low-level form so that it can be mixed with grout for safe transportation and disposal. The material dates back decades and was originally pursued as a fuel for reactors; however, it did not prove to be a viable option.
