Atomic Energy of Canada Limited (AECL), Canadian Nuclear Laboratories (CNL), and the Algonquins of Pikwakanagan First Nation (AOPFN) have signed a long-term relationship agreement that aims to foster mutual respect, collaboration, and economic opportunities between Canada’s indigenous communities and the nuclear industry.

Under terms of the agreement, a working group featuring representation from all three parties will be formed to facilitate ongoing engagements and collaboration among the organizations. This is in addition to the creation of what will be known as the AOPFN Neya Wabun (guardian program), which will establish a regular presence of Pikwakanagan guardians at CNL operations and AECL sites within the territory.

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.

After initial runs using a mix of radiological waste and nonradioactive simulant, the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory site has progressed to treating sodium-bearing waste entirely, the Department of Energy’s Office of Environmental Management (DOE-EM) announced on May 22.

The Department of Energy’s Office of Environmental Management has released its Strategic Vision 2023–2033, a blueprint of the office’s anticipated cleanup achievements over the next decade. DOE-EM said the strategic vision is focused on the priorities of addressing radioactive liquid tank waste, demolishing contaminated buildings, remediating contaminated soil and groundwater, and safely managing and disposing of waste.

“The Strategic Vision 2023–2033 is intended to help us gaze further out to a place we want to be in the future,” DOE-EM senior advisor William “Ike” White said. “It sets EM on a course that will span a decade and inspire us all to achieve EM’s vital nuclear cleanup mission.”

The United States and Canada will cooperate on spent nuclear fuel management under a statement of intent (SOI) signed between the U.S. Department of Energy and the Nuclear Waste Management Organization, the nonprofit responsible for the management of Canada’s commercial spent fuel.

The Department of Energy’s Office of Environmental Management has launched the EM Career Acquisition Program (ECAP) to build a pipeline of trained, experienced acquisition professionals to oversee the procurement and management of cleanup contracts.

Since the launch of operations just over a month ago, the Integrated Waste Treatment Unit (IWTU) at Idaho National Laboratory has increased sodium-bearing waste treatment fivefold. This activity is a vital step in removing the remaining liquid waste from nearby underground tanks at the site and protecting the underlying Snake River Plain Aquifer.

After nearly three years of discussions and more than 60 mediation sessions, the Department of Energy, Washington State Department of Ecology, and the Environmental Protection Agency announced that they have reached a conceptual agreement on revising plans for managing millions of gallons of waste stored in tanks at the Hanford Site near Richland, Wash.

The Department of Energy’s Waste Isolation Pilot Plant (WIPP) recently marked a milestone after its drivers exceeded 16 million safe miles without a serious accident or injury—equivalent to 33 round trips to the moon or more than 642 trips around the world, the DOE’s Office of Environmental Management announced.

The Department of Energy’s Office of Nuclear Energy released an updated version of its consent-based siting process on April 25. The DOE will use the process to engage with willing communities to site one or more consolidated interim storage facilities for commercial spent nuclear fuel, reducing the number of locations where spent fuel is stored and easing the burden on U.S. taxpayers.

The Nuclear Regulatory Commission said it is considering new guidance on the use of decommissioning trust funds for the disposal of major radioactive components from still operating nuclear power plants. A draft guidance document is to be issued for public comment in late May, NRC staff said during a public online meeting on April 13.

More than a decade after construction was declared completed, Idaho’s long-delayed Integrated Waste Treatment Unit (IWTU) has begun radiological operations, the Department of Energy’s Office of Environmental Management (EM) announced.

On Tuesday, crews at the Idaho National Laboratory Site began sending radioactive sodium-bearing liquid waste from nearby underground tanks to the IWTU for treatment. The 900,000 gallons of waste was generated during decontamination activities following spent nuclear fuel reprocessing that ended in 1992.

The IWTU uses steam reforming fluidized-bed reactor technology to convert liquid waste to a granular solid resembling coarse sand more suitable for long-term disposal.

The Department of Energy’s Savannah River Site (SRS) has finalized a high-level waste tank milestones agreement with state and federal regulators that will guide the clean up of the South Carolina site.

The Department of Energy’s Office of Environmental Management (EM) has made great progress in accomplishing its cleanup of legacy radioactive waste but has yet to tackle its most challenging tasks, including the treatment of liquid tank waste at the Hanford, Idaho, and Savannah River sites. That was the consensus of the DOE-EM officials who took part in a panel session of the 2023 Waste Management Symposia, held February 26–March 2 in Phoenix, Ariz.

Attracting more than 2,000 attendees, the 2023 Waste Management Symposia was held February 26–March 2 in Phoenix, Ariz. For many, this year’s conference was a return to business as usual, with a packed exhibit hall and well-attended technical session, as the upheaval brought about by the pandemic that began three years earlier seemed a thing of the pasts. Not that those who gathered in Phoenix threw any caution to the unseasonably cold and rainy winds that descended across Arizona this year.

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.

On December 1, 2021, the Department of Energy issued a request for information (RFI) asking for public feedback on using consent-based siting to identify sites for the interim storage of spent nuclear fuel. The department received more than 220 comments in response, and on September 15, 2022, the DOE released a report summarizing and analyzing those responses. That 57-page report, Consent-Based Siting: Request for Information Comment Summary and Analysis, will be followed by an updated consent-based siting process document.

The DOE’s consent-based siting initiative is being led through the DOE’s Office of Nuclear Energy. To learn more about that initiative and the consent-based siting process, Radwaste Solutions spoke with the DOE’s Kim Petry, acting associate deputy assistant secretary, Spent Fuel and Waste Disposition; Erica Bickford, acting office director, Integrated Waste Management; and Natalia Saraeva, team lead, Consent-Based Siting.

The Energy Communities Alliance (ECA), an organization of local communities near Department of Energy national defense sites, has released a new report urging the DOE to prioritize finding disposal pathways for the radioactive waste it is obligated to clean up.

According to the ECA, the DOE could potentially save hundreds of billions of dollars in cleanup costs by using its available tools and implementing the recommendations contained in the report, Disposal Drives Cleanup: Re-Energizing Momentum for Disposal Solutions for Radioactive Waste.

While still lacking a deep geological repository for the permanent disposal of its commercial used nuclear fuel and high-level radioactive waste, the United States does have regulatory standards for geological nuclear waste disposal.

Having been written nearly 40 years ago, however, those standards are outmoded and lack transparency, according to a special committee of the American Nuclear Society, which has released draft recommendations on revising public health and safety standards for future geological repository projects in the United States.

The Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site (SRS) in South Carolina has resumed operations after a completing a processing improvement that the DOE said will enable safer operations and more efficient vitrification of radioactive waste.
