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.

The Department of Energy will enter into lease negotiations with two solar energy developers for 400 megawatts of solar electricity generation within the Idaho National Laboratory site. Announced on June 5, the projects are the first proposed projects selected under the department’s Cleanup to Clean Energy initiative, an effort to repurpose parts of DOE-owned lands—portions of which were previously used in the nation’s nuclear weapons program—into sites of clean-energy generation, including for solar, geothermal, wind, and nuclear.

A collaboration between the DOE and Bechtel National set a foundation for requirements engineers will follow in continuing the design of the facility. (Photo: DOE)
The Department of Energy’s Office of Environmental Management announced that its Office of River Protection (ORP) recently created a plan with contractor Bechtel National for completing the High-Level Waste Facility at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.

The Defense Nuclear Facilities Safety Board (DNFSB), an independent government organization responsible for overseeing public health and safety issues at Department of Energy defense nuclear facilities, has alerted the DOE because of safety concerns it has regarding the use of continuous air monitors (CAM) at the Waste Isolation Pilot Plant in New Mexico.
Part of WIPP’s new Safety Significant Confinement Ventilation System (SSCVS), the CAM system is intended to detect a radiological release in the repository and automatically close vent dampers to prevent the escape of radioactive particles to the outside environment. The SSCVS, which began commissioning in November 2023, is intended to increase airflow to the underground to allow for simultaneous underground waste emplacement, mining, and ground control work.

Researchers at the Department of Energy’s Argonne National Laboratory are investigating the details of plutonium chemistry with the goal of aiding the cleanup of the Hanford Site in Washington state. For more than 40 years, reactors located at Hanford produced plutonium for America’s defense program, resulting in millions of gallons of liquid radioactive and chemical waste.
