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.

For the first time since forming in 2020, more than 40 members of a Department of Energy team met in person to evaluate technologies, including exoskeletons and wearable robotic devices, that could be adapted to the cleanup mission of department’s Office of Environmental Management (EM), helping improve the safety and well-being of its workers.

The Department of Energy’s Office of Environmental Management (EM) announced that construction of Hanford’s K East Reactor cocoon has been completed ahead of schedule and under budget. Cocooning of K East—enclosing it in a protective steel structure while the reactor’s radioactivity naturally decays—was one of EM’s key construction priorities for 2022.

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.
The decommissioning of ORNL’s aging research reactors is clearing the stage for future missions at the site.

The Department of Energy and its environmental cleanup contractor United Cleanup Oak Ridge (UCOR) are poised to meet critical milestones as they continue to move to the next generation of cleanup at Oak Ridge National Laboratory in Tennessee. On ORNL’s main campus, crews on “Reactor Hill”—so named because of the four remaining reactor facilities on that hillside—and at the Experimental Gas-Cooled Reactor (EGCR) just east of the campus continue rigorous schedules as they enter a new phase of progress in the cleanup program.

The Department of Energy’s Office of Environmental Management (EM) announced on October 18 that it has begun the process of transferring primary authority of South Carolina’s Savannah River Site (SRS) to the National Nuclear Security Administration, with the transfer expected to be completed in 2025.

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.

Work crews at the Department of Energy’s Oak Ridge Site in Tennessee have successfully completed the demolition of the former Criticality Experiment Laboratory. Crews worked this past summer to bring down the dilapidated 1940s-era facility, also known as Building 9213.

The Department of Energy has extended Savannah River Nuclear Solutions’ (SRNS) management and operating contract at the Savannah River Site (SRS) in South Carolina for up to an additional five years. The announcement was made recently 29 by engineering company Fluor, which leads the SRNS joint venture, along with Newport News Nuclear and Honeywell.

Based on a review of U.S. Atomic Energy Commission (AEC) records and available data from numerous agencies, there are an estimated 4,225 mines across the country that provided uranium ore to the U.S. government for defense-related purposes between 1947 and 1970. To aid in the cleanup of these legacy uranium mines and establish a record of their locations and current conditions, the Defense-Related Uranium Mines (DRUM) program was established within the Department of Energy’s Office of Legacy Management (LM).

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.

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.
