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.

Saying they are cautiously optimistic that the Biden administration can change the U.S. trajectory on nuclear waste, some Stanford University experts have offered their recommendations on how it can be done in a recent Stanford news posting.

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.

New Mexico attorney general Hector Balderas has filed suit against the Nuclear Regulatory Commission and the United States, seeking to stop Holtec International’s application to build and operate its HI-STORE consolidated interim storage facility for used nuclear fuel in the state. The complaint, filed in the U.S. District Court of New Mexico on March 29, seeks a declaratory judgment that the NRC is acting beyond the scope of its authority and an injunction preventing the licensing from moving forward.

The month of March marked the 25th year of radiological operations for the Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site in South Carolina. Radiological operations at DWPF, which is used to treat Savannah River’s high-level radioactive tank waste, began on March 12, 1996, with the first canister of vitrified waste poured on April 29 that year.
To date, more than 4,200 stainless steel canisters of vitrified waste have been poured at DWPF, according to the DOE.
The only operating waste vitrification plant in the nation, DWPF is operated by Savannah River Remediation, the DOE’s liquid waste contractor at the site. According to the DOE, DWPF operations are expected to continue for approximately 15 more years, and about 4,000 more canisters are scheduled to be produced. The DOE expects to begin hot operations at a second waste vitrification plant later this year at its Idaho National Laboratory site.
