The Department of Energy’s Office of Environmental Management (EM) said that heat-up of Idaho’s Integrated Waste Treatment Unit (IWTU) resumed in January. Crews began heating the IWTU in December in preparation of radiological operations, but the facility was shut down 10 days later after operators noticed a small leak of nonradioactive material inside one of the unit’s processing cells.

Located at the DOE’s Idaho National Laboratory Site, the IWTU is intended to treat Idaho’s 900,000 gallons of sodium-bearing liquid waste, converting it to a solid using a steam-reforming process.

After repairs were made to the IWTU equipment responsible for the leak, crews removed a partial obstruction that was in a line into the carbon reduction reformer, a key treatment vessel in the steam-reforming process, EM said.
