Hanford’s waste vitrification operations are unlikely to start by the Department of Energy’s year-end goal, said Brian Vance, manager of the DOE’s Office of River Protection and Richland Operations Office for the Hanford Site in Washington state. The DOE is working to meet its obligations to begin processing Hanford’s low-level radioactive tank waste as part of its Direct-Feed Low-Activity Waste (DFLAW) program.

“The probability for 2023 is very low,” Vance said, regarding the department’s plan to begin vitrifying the tank waste. Vance made his remarks during a panel session of the 2023 Waste Management Symposia in Phoenix, Ariz., on February 28.

The Department of Energy is asking for feedback on a new report analyzing potential options for preparing high-level radioactive waste for vitrification at the department’s Hanford Site near Richland, Wash. Vitrification is the process of treating radioactive waste by immobilizing it in glass.

The report, Waste Treatment and Immobilization Plant High-Level Waste Treatment: Analysis of Alternatives, was commissioned in response to a 2018 determination by the U.S. Army Corps of Engineers that it was unlikely the DOE would meet its mandated deadlines for treating Hanford’s tank waste.

Looking back at 2022—October through December

January 6, 2023, 9:09AMNuclear News

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from September through December 2022.

But first:

Heating of the first waste vitrification melter at the Department of Energy’s Hanford Site was paused after operators identified an “abnormal condition with the startup heater power supplies,” the DOE’s Office of River Protection (ORP) said. Heat-up of the 300-ton melter, which will be used to vitrify Hanford’s low-level radioactive tank waste, was initiated on October 8.

Crews at the Department of Energy’s Hanford Site, near Richland, Wash., have begun heating up the first of two 300-ton melters that will be used to vitrify mixed low-level radioactive and chemical tank waste. According to the DOE’s Office of Environmental Management (EM), initiating and completing the heating of the melter is a critical step to commissioning Hanford’s Waste Treatment and Immobilization Plant (WTP), which will treat and stabilize the site’s 56 million gallons of tank waste by immobilizing it in glass through the vitrification process.

DOE releases 5-year Hanford cleanup plan

October 11, 2022, 9:37AMRadwaste Solutions

By fiscal year 2027, Hanford’s Waste Treatment and Immobilization Plant (WTP) will ramp up toward producing 21 metric tons of low-level radioactive glass a day, according to the Department of Energy’s five-year plan for the site near Richland, Wash.

The plan, which was released on October 3 and opened for a 31-day public comment period, outlines what cleanup work will be initiated or completed at the Hanford Site during FYs 2023–2027.

This spring, the U.S. Government Accountability Office (GAO) released an insightful report reviewing and summarizing the status and performance of the largest projects and operations within the Department of Energy’s Office of Environmental Management (EM), which is responsible for the cleanup of hazardous and radioactive waste at sites and facilities that have been contaminated from decades of nuclear weapons production and nuclear energy research.

Atkins breaks ground on new technology center near Hanford Site

September 20, 2022, 7:00AMRadwaste Solutions

Atkins Nuclear Secured Holding Corporation, a member of the SNC-Lavalin Group, celebrated the start of construction on its new, $20 million, state-of-the-art Atkins Technology Center (ATC) with a ground-breaking ceremony held on September 13 in Richland, Wash. Located near the Department of Energy’s Hanford nuclear reservation, the facility will be adjacent to the existing Atkins Engineering Laboratory.

Vit Plant delayed: Another defeat for cleaning up nuclear waste at Hanford

September 19, 2022, 12:37PMNuclear NewsJames Conca

The Hanford tanks, on which building began in 1943, were never supposed to hold waste for many decades. If grouting and disposal had occurred according to plans from the 1980s, this waste would already be in the ground and we would have saved almost $100 billion. (Photo: DOE)

At the end of June, a federal judge approved, with the agreement of the Washington State Department of Ecology, a request to push back the deadline 20 months for beginning nuclear waste treatment at the $17 billion Waste Treatment and Immobilization (Vit) Plant at the Hanford Site because of pandemic-related delays. The Direct-Feed Low-Activity Waste program is the Department of Energy’s plan to start treating low-level radioactive waste first at the Vit Plant and then start treating high-level radioactive waste sometime in the 2030s.

This is the fifth delay granted by the court for the project, which should have begun operations in 2007. In one sense, this delay is good, since turning LLW into glass through vitrification is about as smart as singing into the wind. The chemistry of this waste makes it much better suited to grouting, a treatment used by everyone else in the United States and the world.

New transfer lines installed on Hanford tank waste evaporator

Washington state’s Department of Ecology and the U.S. Department of Energy have agreed on a plan for how to respond to two underground tanks that are leaking radioactive waste, as well as any future tank leaks, at the Hanford Site near Richland, Wash.

In April 2021, following a year-long leak assessment, the DOE announced that Hanford’s Tank B-109 is leaking waste into the surrounding soil. Tank T-111 was discovered to be leaking in 2013. Currently, Tank B-109 is leaking about 1.5 gallons of waste per day, and Tank T-111 is leaking less than a gallon a day, according to the DOE.
