The Department of Energy is preparing for an upcoming campaign to dissolve stainless-steel-clad spent nuclear fuel at its Savannah River Site in South Carolina by installing a new dissolver and an additional double-sized tank for storing dissolved material.

The Salt Waste Processing Facility at the Department of Energy’s Savannah River Site has performed largely as expected, processing more than one million gallons of radioactive waste during its first eight months of operation, the DOE reported on June 8. The SWPF is being used to treat the majority of the site’s remaining liquid radioactive waste, generated from the production of nuclear materials.

Final cleanup activities at the Hanford Site’s demolished Plutonium Finishing Plant have resumed following a pause in work prompted by the COVID-19 pandemic, the Department of Energy announced. Crews with the DOE’s Richland Operations Office and site contractor Central Plateau Cleanup Company will remove, package, and dispose of rubble remaining from the demolition of the plant’s plutonium reclamation facility, which was torn down in 2017.

The Department of Energy has announced up to $40 million in funding for a new Advanced Research Projects Agency-Energy (ARPA-E) program to conduct research and development into technologies for reprocessing and ultimately disposing of used nuclear fuel. The program, “Optimizing Nuclear Waste and Advanced Reactor Disposal Systems” (ONWARDS), announced on May 19, targets both open (once-through) and closed (reprocessing) fuel cycles to reduce the amount of waste produced from advanced reactors tenfold when compared to light water reactors.

Workers at the Department of Energy’s Hanford Site near Richland, Wash., recently completed testing a mock-up of a system that will be used to isolate and stabilize about 15,000 pounds of radioactive debris in the site’s K West Reactor spent fuel storage basin.
The NWTRB’s six overarching recommendations for the DOE’s nuclear waste management program.

Nuclear Waste Partnership (NWP), the management and operations contractor for the Department of Energy’s Waste Isolation Pilot Plant in southeastern New Mexico, announced that it has awarded a subcontract valued at approximately $163 million to The Industrial Company (TIC) to complete the construction of the transuranic waste repository’s Safety Significant Confinement Ventilation System (SSCVS).

The Waste Isolation Pilot Plant in southeastern New Mexico is once again accepting shipments and processing transuranic waste following a two-month annual maintenance outage. According to the Department of Energy, WIPP is back to accepting five waste shipments per week, with post-pandemic plans to increase shipments to 10 per week.

A new wastewater filter system being installed at Hanford’s Effluent Treatment Facility (ETF) is expected to increase waste processing throughput, improve efficiency, and save money as the site in southeastern Washington gears up to treat tank waste, the Department of Energy announced.
