Employees have begun emplacing defense-related transuranic (TRU) waste in Panel 8 of the Waste Isolation Pilot Plant (WIPP) in New Mexico, the Department of Energy’s Office of Environmental Management (EM) announced in November. TRU waste is permanently disposed of at WIPP in rooms mined in a Permian salt bed 2,150 feet below the surface.

Contractor employees at the Department of Energy’s Savannah River Site in South Carolina recently exceeded their plutonium downblending goal for 2022 ahead of schedule as part of the ongoing activities to remove Pu from the state, the DOE’s Office of Environmental Management (EM) announced.

Heating of the first waste vitrification melter at the Department of Energy’s Hanford Site was paused after operators identified an “abnormal condition with the startup heater power supplies,” the DOE’s Office of River Protection (ORP) said. Heat-up of the 300-ton melter, which will be used to vitrify Hanford’s low-level radioactive tank waste, was initiated on October 8.

Crews at the Department of Energy’s Hanford Site, near Richland, Wash., have begun heating up the first of two 300-ton melters that will be used to vitrify mixed low-level radioactive and chemical tank waste. According to the DOE’s Office of Environmental Management (EM), initiating and completing the heating of the melter is a critical step to commissioning Hanford’s Waste Treatment and Immobilization Plant (WTP), which will treat and stabilize the site’s 56 million gallons of tank waste by immobilizing it in glass through the vitrification process.
Demolition of the MPPB, one of the last remaining major facilities at WVDP, is expected to be completed in about 30 months. (Photo: DOE)
The Department of Energy’s Office of Environmental Management (EM) said it has met one of its cleanup priorities for 2022 by beginning demolition of the Main Plant Process Building (MPPB) at the West Valley Demonstration Project (WVDP) in New York. Located 35 miles south of Buffalo, the 150-acre WVDP site is home to the only commercial spent nuclear fuel reprocessing facility to operate in the United States.

This spring, the U.S. Government Accountability Office (GAO) released an insightful report reviewing and summarizing the status and performance of the largest projects and operations within the Department of Energy’s Office of Environmental Management (EM), which is responsible for the cleanup of hazardous and radioactive waste at sites and facilities that have been contaminated from decades of nuclear weapons production and nuclear energy research.
Spain’s nuclear power plants are to use Holtec’s HI-STORM spent fuel storage technology. (Image: Holtec)
Holtec International announced that its flagship HI-STORM Multi-Purpose Canister (MPC) spent fuel storage technology was selected by Spain’s national company Enresa for a fleet of six nuclear power reactors at four plant sites in the country. Equipos Nucleares S.A. (ENSA), a Cantabria-based manufacturer of equipment for the Spanish nuclear fleet, was named a consortium partner with Holtec in the order, which was conducted under European Union procurement rules.

Nagra, Switzerland’s national cooperative for the disposal of radioactive waste, has announced that it has selected Nördlich Lägern as the site for a deep geological repository for radioactive waste. According to Nagra, extensive investigations have shown that Nördlich Lägern, located in northern Switzerland near the German border, is the most suitable area for a geologic repository with the best overall safety reserves.

Washington state’s Department of Ecology and the U.S. Department of Energy have agreed on a plan for how to respond to two underground tanks that are leaking radioactive waste, as well as any future tank leaks, at the Hanford Site near Richland, Wash.
In April 2021, following a year-long leak assessment, the DOE announced that Hanford’s Tank B-109 is leaking waste into the surrounding soil. Tank T-111 was discovered to be leaking in 2013. Currently, Tank B-109 is leaking about 1.5 gallons of waste per day, and Tank T-111 is leaking less than a gallon a day, according to the DOE.

The Department of Energy’s Office of Environmental Management (EM) announced that it is preparing for construction of the final three planned saltstone disposal units (SDUs) at the Savannah River Site in South Carolina, which will complete the site’s liquid waste mission.
The SRS liquid waste contractor, Savannah River Mission Completion (SRMC), is overseeing the construction of the SDUs, which will receive decontaminated salt solution treated at Savannah River’s Salt Waste Processing Facility (SWPF).

Canada’s Nuclear Waste Management Organization (NWMO) is shifting the timing for selecting a preferred site for a spent nuclear fuel repository to the fall of 2024, a full year later than previously planned. The NWMO, a nonprofit organization tasked with the safe, long-term management of Canada’s spent fuel in a deep geological repository, said the delay is the result of several provincial lockdowns associated with the COVID-19 pandemic.
Members of the UCOR team receive their award at a Top Workplaces event.
United Cleanup Oak Ridge (UCOR), the lead environmental cleanup contractor for the Department of Energy’s Oak Ridge Office of Environmental Management (OREM), has been named one of the Knoxville News Sentinel’s “Top Workplaces” in eastern Tennessee for 2022. The award is the result of a confidential, third-party survey of UCOR’s 2,000-member workforce by the Knoxville News Sentinel and the survey company Energage.
