The Department of Energy’s Office of Environmental Management announced last week that, for calendar year 2023, the department’s Waste Isolation Pilot Plant (WIPP) had its best shipment performance in 10 years, having received 489 transuranic (TRU) waste shipments from generator sites throughout the country. For comparison, WIPP received only 272 shipments in 2022.

The Department of Energy’s Office of Environmental Management has released its program priorities for calendar year 2024, covering key cleanup actions, project construction, acquisition, and other important activities that will further the office’s mission of addressing the environmental legacy of the nation’s nuclear research and weapons development.

For the first time in a decade, crews have started mining a new disposal panel at the Department of Energy’s Waste Isolation Pilot Plant (WIPP) in New Mexico, the nation’s deep geologic waste repository for defense-related transuranic waste.

The Department of Energy announced that its Oak Ridge Office of Environmental Management (OREM) is moving ahead with a slate of projects this year that will alter the Tennessee site’s skyline, remove inventories of nuclear waste, and complete a major phase of cleanup.

The Department of Energy’s Office of Environmental Management issued for public comment the first request for qualifications (RFQ) related to the department’s Cleanup to Clean Energy initiative, which aims to increase energy production by making DOE land available for the potential development of carbon-free energy (CFE) electricity generation through leases.

The Department of Energy’s Office of Environmental Management has issued a draft request for proposal for technical support services contract for the Portsmouth/Paducah Project Office (PPPO), which manages the department’s cleanup efforts at the two gaseous diffusion plant sites in Ohio and Kentucky.

The Department of Energy’s Office of Environmental Management said Idaho’s Integrated Waste Treatment Unit (IWTU) is set to resume radioactive liquid waste treatment operations early next year after crews replaced carbon material from two plant vessels. The IWTU was shut down for an unplanned outage on September 6 to address elevated mercury concentrations in the plant’s granulated activated carbon (GAC) beds, according to Defense Nuclear Facilities Safety Board (DNFSB) reports.

The Department of Energy’s Office of Environmental Management released a competitive funding opportunity announcement (FOA) on December 6 for the Community Capacity Building Grant Program, aimed at communities affected by DOE-EM’s mission to clean up legacy nuclear waste.

Bechtel and the Department of Energy’s Office of Environmental Management announced on December 4 that the first set of test glass was successfully poured into a stainless-steel storage container designed to hold vitrified waste at Hanford’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.

Personnel from the Department of Energy’s Office of Environmental Management and the National Nuclear Security Administration recently gathered to discuss plans for the upcoming transfer of landlord responsibility for the Savannah River Site in South Carolina.

Commissioning has begun on a new large-scale ventilation system at the Waste Isolation Pilot Plant in New Mexico.

The Safety Significant Confinement Ventilation System (SSCVS) is expected to increase underground airflow from 170,000 cubic feet per minute up to 540,000 cfm. The increased airflow will allow for simultaneous underground waste emplacement, mining, and ground control work. Ground control, including bolting, controls the movement of salt rock—known as salt creep—in the WIPP underground.

The Department of Energy’s Office of Environmental Management said crews at its Hanford Site in Washington state have started pouring the first molten glass from a waste vitrification melter into a stainless steel container at the site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.

The Department of Energy’s Office of Environmental Management said that crews at the Idaho National Laboratory site are making “significant progress” decommissioning the Submarine 1st Generation Westinghouse (S1W) reactor, the prototype pressurized water reactor that supported the development of the USS Nautilus, the world’s first operational nuclear-powered submarine.

The Department of Energy has released two additional requests for information related to its Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands—portions of which were previously used during the nation’s nuclear weapons program—into sites for clean energy generation, including include solar, geothermal, wind, and nuclear electricity.

The Department of Energy’s Office of Environmental Management said a new regulatory partnership framework established in recent years by the Oak Ridge Office of Environmental Management (OREM), its contractor United Cleanup Oak Ridge (UCOR), the Environmental Protection Agency, and the Tennessee Department of Environment and Conservation (TDEC) is ushering in a new chapter of accelerated cleanup at the department’s Oak Ridge Reservation in Tennessee.

The Department of Energy’s Office of Environmental Management, which is responsible for the cleanup of 15 nuclear sites across the country, lacks a clear understanding of its costs for work not directly related to site cleanup, hampering the department’s ability to prioritize competing funding needs, according to a report by the Government Accountability Office.

The Department of Energy’s Office of Environmental Management announced it has completed a second of its 2023 priorities at Oak Ridge in as many months with the demolition of the Low Intensity Test Reactor, known as Building 3005, at the Tennessee site.
