Long-idled design work resumed this summer on the high-level waste portion of the Waste Treatment and Immobilization Plant at the Department of Energy’s Hanford Site in Washington state, according to the Defense Nuclear Facilities Safety Board. After August workshops, prime contractor Bechtel National and DOE created what they call the “HLW [High Level Waste] Firm […]

The Hanford Site in Washington may not be able to make its first canister of glass from low-level radioactive tank waste until 2024, a year later than the Department of Energy hoped, an agency official said Thursday at a public meeting in New Orleans. “We originally had hoped to have hot commission by December” of […]

After an alarm on a control panel, the Department of Energy has temporarily stopped heating up the first melter for the Waste Treatment and Immobilization Plant at the Hanford Site in Washington state, an advisory panel was told Thursday. The news was shared with a virtual meeting of the Hanford Advisory Board by Mat Irwin, […]

As the top boss at the Department of Energy’s nuclear cleanup office promised last week, crews at the Hanford Site in Washington state are heating up a giant melter designed to solidify radioactive tank waste into a glass form at the $17-billion Waste Treatment and Immobilization Plant. The DOE began heating up the 300-ton melter […]

The Tri-City Herald newspaper in Richland, Wash., reported […]

While changes in a legally-binding consent decree allow the Department of Energy more time to start turning low-level radioactive tank waste into glass at the Hanford Site in Washington state, the agency’s goal is still to start the work by the end of 2023, the top fed at the property said Wednesday. While DOE has […]

Veolia Nuclear Solutions Federal Services last week dedicated a new low-level radioactive waste vitrification facility at the Waste Control Specialists site in Andrews County, Texas, according to a release on LinkedIn. Veolia Nuclear Solutions Federal Services (VNS Federal Services), which is a Department of Energy contractor, held a ribbon-cutting ceremony June 15 for its new […]

The Defense Waste Processing Facility at the Department of Energy’s Savannah River Site in South Carolina has entered an outage this month as it prepares to switch over from formic acid to glycolic acid by October. Going with glycolic acid at the Defense Waste Processing Facility (DWPF) should lead to more efficient conversion of radioactive […]

Department of Energy managers at the Savannah River Site in South Carolina expect the Salt Waste Processing Facility to process 4 million gallons of waste this year, they told a DOE-chartered advisory group Monday. The prediction was offered by Michael Budney, Savannah River Site manager for DOE’s Office of Environmental Management, in response to questions […]

Washington state regulators probably will not allow the Department of Energy to solidify the Hanford Site’s liquid tank waste with grout-like cement until and unless the parties agree to permit disposal methods for liquid waste other than immobilization in glass, officials told a National Academies of Sciences panel Thursday. “Ecology considers on-site grout disposal to […]

Should the Department of Energy’s Hanford Site in Washington state decide to grout much of its supplemental low-activity waste at an existing off-site facility, the process could start as early as 2027, a Savannah River National Laboratory official told a National Academies of Sciences panel Tuesday in Richland, Wash. Dan McCabe, senior scientist from the […]

After a probe, the Department of Energy’s Office of Inspector General could not substantiate claims of cheating and other problems with Bechtel’s substance abuse program at the Waste Treatment Plant at the Hanford Site in Washington state. “Specifically, we found that management had taken several actions to address drug-related concerns,” the Office of Inspector General […]

Department of Energy and Washington state Department of Ecology managers reassured the Hanford Advisory Board Wednesday their agencies remain interested in the Test Bed Initiative to grout 2,000 gallons of low-activity tank waste that would be shipped out of state. Brian Vance, the DOE’s manager for the Hanford Site, expects the Nuclear Regulation Commission to […]

The Salt Waste Processing Facility, offline since late October at the Department of Energy’s Savannah River Site in South Carolina, should resume operation within a couple of weeks, an executive with Parsons Corp., which built the plant told an advisory panel Tuesday. “We are shut down currently,” Mike Pittman, a Parsons vice president and project […]

The liquid waste contractor at the Department of Energy’s Savannah River Site in South Carolina is seeking expressions of interest from firms that could build three new saltsone disposal units at the federal complex near the Georgia line. Amentum-led Savannah River Remediation (SRR) posted the notice Thursday on the government procurement website, SAM.gov for Saltstone […]

The Department of Energy expects to issue a finding by July 2022 on the practicality of solidifying 2,000 gallons of tank waste at the Hanford Site in Washington using concrete-like grout, federal officials said during an online public meeting Thursday. But before DOE issues the finding, the Nuclear Regulatory Commission (NRC) was expected to check […]

While not flat-out opposed to future use of grout for radioactive tank waste at the Department of Energy’s Hanford Site, state officials in Washington and Oregon said Thursday feds for now should not become distracted from the more immediate task of converting low-activity waste into a stabler glass form. Direct-feed low-activity waste (DFLAW) treatment at […]

Personnel at the Department of Energy’s Hanford Site recently tested a drainage system that will funnel byproducts of liquid waste cleanup to an outbuilding from the Low Activity Waste Facility, the Department of Energy’s Office of Environmental Management said this week. The system includes large tanks and miles of pipes inside the Low-Activity Waste Facility […]

By John Stang The first melter at Hanford’s first vitrification facility is scheduled to start up in December, site officials told the Hanford Advisory Board this week, teeing up the long-awaited solidification of liquified Cold War plutonium-byproducts by 2023. After the startup, it should take two months to increase the melter’s temperature to 2,100 degrees […]
