The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.

ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.

Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

Upgrades are underway at the Department of Energy’s Hanford Site to prepare its 222-S Laboratory to treat tank waste under the Direct-Feed Low-Activity Waste (DFLAW) program.

The Department of Energy’s Office of Environmental Management once again awarded a 10-year, $45 billion contract to Hanford Tank Waste Operations and Closure (H2C) of Lynchburg, Va., for the cleanup of tank waste at the Hanford Site.

The Department of Energy’s Office of Environmental Management announced that crews at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, recently installed 18 temporary startup heaters in the second of two melters in the plant’s Low-Activity Waste Facility.

The documentary film Richland, which won awards at the Tribeca Festival and Sheffield (U.K.) DocFest last year, continues to gain exposure. Directed by Irene Lusztig, a self-described “feminist filmmaker, archival researcher, educator, and seamstress,” the documentary explores the community and “nuclear origin story” of Richland, Washington, a town that was built by the U.S. government to house Hanford Site workers who made the weapons-grade plutonium for the atomic bombs of the Manhattan Project.

Washington State University offered a free screening of the documentary last week at its main Pullman campus, followed by a discussion with the director and Robert Franklin, an assistant professor in history at the university’s Tri-Cities campus and the assistant director and archivist for the Hanford History Project.

The training team at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP) recently added an extra level of realism to employee trainings by upgrading classrooms and adding new props, according to the Department of Energy.

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.

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.

The Department of Energy’s Office of Environmental Management is responsible for roughly 90 million gallons of radioactive liquid waste at Idaho National Laboratory, the Hanford Site in Washington state, and the Savannah River Site in South Carolina. About 900,000 gallons of waste are stored at INL, 56 million gallons at Hanford, and roughly 36 million at SRS. A further 400,000 gallons of waste from various operations are being stored at the Oak Ridge Site in Tennessee.

The Hanford Site’s Effluent Treatment Facility (ETF) has been expanded and will be able to handle almost 7 million more gallons of wastewater per year once the site’s Waste Treatment and Immobilization Plant (WTP) begins treating waste from large underground tanks.

The Department of Energy is seeking the public’s input on the Hanford Site’s 5-year plan, which outlines planned cleanup work either to be completed or initiated at the former plutonium production site near Richland, Wash. The DOE updates Hanford’s 5-year plan annually to reflect current progress and ongoing integrated planning for future work at the site.

Washington state’s Department of Ecology said it has reached a settlement with the Department of Energy over access to data the state described as “critical” to the cleanup of the Hanford Site near Richland, Wash.

Workers at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, have begun removing the first three of 18 temporary startup heaters, the Department of Energy announced on September 12. The startup heaters were used to raise the first of two 300-ton glass melters in the plant’s Low-Activity Waste Facility to its operating temperature of 2,100°F.

The Department of Energy has released the first request for information (RFI) related to the department’s Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands, portions of which were previously used in the nation’s nuclear weapons program, into sites for clean energy generation.

Demolition is underway on several former chemical storage tanks and associated infrastructure near the Plutonium Uranium Extraction (PUREX) plant, the final and most advanced chemical separations facility at the Department of Energy’s Hanford Site.

The project is expected to be completed by the end of September.

The Department of Energy’s Hanford Site has introduced its newest team members, Dee and Freda, two highly skilled explosive-detecting K-9 officers. The police dogs will work with Richland Operations Office contractor Hanford Mission Integration Solutions to help ensure the safety and security of the legacy nuclear reservation near Richland, Wash.

The Department of Energy’s Office of Environmental Management announced that the first batches of glass-forming beads, called frit, were poured last week into a melter at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant. The melter, which has been heated to 2,100ºF, will be used to immobilize Hanford’s radioactive and chemical tank waste, turning it into a stable glass form through vitrification.

The Department of Energy announced last week that Melter 1 at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, has hit its operational temperature of 2,100ºF. The DOE began heating Melter 1 in October 2022, but was soon forced to pause when abnormalities in the heaters’ power supply were encountered.

A pair of recent reports by the U.S. Government Accountability Office and the National Academies of Science, Engineering, and Medicine highlight some of the challenges the Department of Energy faces in treating the millions of gallons of legacy radioactive waste at the Hanford Site in Washington state.
