The Department of Energy is proposing to fully decommission the Submarine 5th Generation General Electric (S5G) prototype at the Naval Reactors Facility on the Idaho National Laboratory site. Along with the Environmental Protection Agency and the state of Idaho, the DOE has initiated a 30-day public comment period (ending November 14) on the planned end state for the facility and its defueled reactor vessel.

Beginning last week, the two Department of Energy offices responsible for the environmental cleanup of the department’s Hanford Site have been combined under a new name: the Hanford Field Office. Previously, management of the 586-square-mile site near Richland, Wash., was split between the Richland Operations Office and the DOE Office of River Protection (ORP).

Nearly six years after it was first announced, the Department of Energy has transitioned landlord responsibilities at the Savannah River Site from the Office of Environmental Management to the National Nuclear Security Administration. The shift will align with the start of federal fiscal year 2025.

Workers with the Oak Ridge Office of Environmental Management (OREM) and its contractor UCOR have finished installing the first of three large sludge-settling tanks for the Mercury Treatment Facility at the site’s Y-12 National Security Complex. The tanks, each of which will be 38 feet tall and 15 feet wide with a capacity of 36,000 gallons, provide a visible sign of ongoing progress on the facility where much of the construction has so far been below ground.

Regardless of who is sitting in the Oval Office next year, the Department of Energy’s Office of Environmental Management needs to take a close look at itself and “launch a comprehensive review of all aspects of the EM program,” according to a new report from the Energy Communities Alliance, which represents communities adjacent to or near DOE nuclear cleanup sites.

The 18-page ECA transition paper, Ensuring Long-Term Success: Recommendations for the Next Administration on the U.S. Department of Energy’s Environmental Management Mission, calls on the next administration to “take a fundamental look” at DOE-EM’s entire cleanup effort, including both sites that are active and those where work has been completed. How DOE-EM integrates with other DOE programs, including the National Nuclear Security Administration and the offices of Nuclear Energy, Science, and Legacy Management, should also be examined, according to the paper.

Workers with the Department of Energy Office of Environmental Management’s contractor Central Plateau Cleanup Company recently demolished a former chemical storage area at the Reduction Oxidation Plant, one of five former plutonium production facilities at the Hanford Site.

Juno Beach, Fla.–based NextEra Energy Resources Development has been selected to enter realty negotiations for a large-scale solar electricity generation project at the DOE’s Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico as part of the department’s Cleanup to Clean Energy initiative.

The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

The Department of Energy has released a notice of a funding opportunity (DE-FOA-0003422) for the department’s Office of Environmental Management Minority Serving Institutions Partnership Program (MSIPP). With an estimated value of $15.5 million, the funding opportunity is a set-aside for minority-serving institutions (MSIs) and will result in multiple financial assistance awards ranging from one year to three years in length.

According to the Department of Energy’s Office of Environmental Management, two contractors at its Hanford Site in Washington state have finished a first-time relay of test glass as the site prepares to vitrify—or immobilize in glass—millions of gallons of radioactive and chemical waste from its large underground tanks.

The Energy Communities Alliance (ECA), which advocates for communities adjacent to or impacted by Department of Energy sites, is asking the department to conduct an independent analysis evaluating the impacts of delaying the implementation of its statutory interpretation of high-level radioactive waste, which holds that some waste from the reprocessing of spent nuclear fuel may be classified as non-HLW.

The Department of Energy’s Office of Environmental Management will begin using drones for the first time to internally inspect radioactive liquid waste tanks at the department’s Savannah River Site in South Carolina. Inspections were previously done using magnetic wall-crawling robots.

The Department of Energy’s Office of Environmental Management has issued a request for qualifications related to the department’s Cleanup to Clean Energy initiative for utility-scale energy projects at the Savannah River Site in South Carolina.

Crews are making significant progress on the construction of the K-25 viewing platform at the Oak Ridge Reservation in Tennessee, the Department of Energy’s Office of Environmental Management announced on August 20. When completed next year, the elevated platform will offer a sweeping panoramic view of the massive 44-acre footprint of the K-25 Building, which once produced enriched uranium used in the weaponry that ended World War II.

The Department of Energy’s Office of Environmental Management has issued a final request for proposals for an infrastructure support services (ISS) contract at the department’s Paducah Site in Kentucky, which is the former home of the Paducah gaseous diffusion uranium enrichment plant. DOE-EM has conducted extensive cleanup and environmental remediation activities at the site since the late 1980s.

Despite efforts to increase hiring, the Department of Energy’s Office of Environmental Management continues to be understaffed, according to a recent Government Accountability Office report. The GAO found that, at the end of fiscal year 2023, DOE-EM had 263 vacant positions across its headquarters, cleanup sites, and EM Consolidated Business Center—a vacancy rate of 17 percent. The office is responsible for the cleanup of the environmental legacy waste resulting from decades of nuclear weapons production and government-sponsored nuclear energy research.

The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $630 million to Louisiana-based Aptim Federal Services for deactivation and decommissioning work at two U.S. Naval Nuclear Propulsion Program sites in New York.

The Department of Energy’s Office of Environmental Management announced that it has completed construction of the new large-scale ventilation system at its Waste Isolation Pilot Plant in New Mexico.

With the placement of 25 wall sections, 208 support columns, and 7 roof sections, work crews have completed all major concrete placements for the megavolume Saltstone Disposal Unit (SDU) 10 at the Savannah River Site in South Carolina, according to the Department of Energy’s Office of Environmental Management.

The Department of Energy’s Office of Environmental Management and its contractor Washington River Protection Solutions (WRPS) recently demonstrated the use of cold spray technology as a means of refurbishing double-shell waste tanks at the Hanford Site in Washington state. The tanks store liquid radioactive and chemical waste that was created during Hanford’s plutonium production era.
