Idaho’s IWTU resumes heat-up following repairs

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.

Australian emergency services has located the lost sealed source, the BBC reported early February 1.

The cesium-137 capsule, part of a density gauge used at Rio Tinto’s Gudai-Darri mine in Western Australia, was found after a survey vehicle travelling at 70 km/h (43 mph) detected radiation, according to the report. According to Australia’s Department of Fire and Emergency Services, the capsule was located on the roadside of the Great Northern Highway, south of Newman. A serial number verified it was the lost source.

Last week, as reported yesterday by Nuclear Newswire, Australian authorities began searching 1,400 kilometers (870 miles) of Australia’s Great Northern Highway, between Perth and the remote town of Newman, for a lost sealed-source capsule containing cesium-137. The source was part of a density gauge used by mining company Rio Tinto at its mining operations in Western Australia.

DOE cleanup teams win Secretary of Energy achievement awards

The Department of Energy recently honored eight teams from its Office of Environmental Management (EM) with Secretary of Energy 2022 Achievement Awards. The awards recognized projects at the DOE’s Idaho, Savannah River, and Hanford sites, as well as a group of employees that revamped and expanded DOE-EM’s Minority Serving Institutions Partnership Program (MSIPP-EM). In addition, DOE-EM employees on crosscutting departmental teams received awards.

The awards were part of the DOE’s annual Honor Awards, the agency’s highest form of employee recognition for excellence and achievement.

Deep Isolation to launch demonstration center for borehole disposal

Nuclear waste management start-up Deep Isolation has announced the formation of a new Deep Borehole Demonstration Center. The new nonprofit organization will seek to advance the maturity of the safety case for deep borehole disposal and the technical readiness levels of the borehole disposal concept, including characterization, construction, canister handling, emplacement, and retrieval.

DOE seeks input on analysis of alternatives for treating Hanford’s HLW

The Department of Energy is asking for feedback on a new report analyzing potential options for preparing high-level radioactive waste for vitrification at the department’s Hanford Site near Richland, Wash. Vitrification is the process of treating radioactive waste by immobilizing it in glass.

The report, Waste Treatment and Immobilization Plant High-Level Waste Treatment: Analysis of Alternatives, was commissioned in response to a 2018 determination by the U.S. Army Corps of Engineers that it was unlikely the DOE would meet its mandated deadlines for treating Hanford’s tank waste.

DOE increases consent-based siting FOA to $26 million

The Department of Energy has increased the funding level for its community engagement on consent-based siting funding opportunity announcement (FOA) from $16 million to $26 million. The DOE first announced it was making funding available to communities interested in learning more about consent-based siting, management of spent nuclear fuel, and interim storage facility siting considerations last September. The FOA follows the DOE’s recent update to its consent-based process for siting an interim storage facility for SNF.
