Robert P. Martin and Thomas E. Roberts have been appointed to four-year terms on the Advisory Committee on Reactor Safeguards, the Nuclear Regulatory Commission announced on July 20.

Researchers from the Pusan National University in South Korea have developed a new calcium-doped ion exchanger for the removal of radioactive cesium from acidic nuclear power plant wastewater. The findings have the potential for developing more efficient and effective methods of remediating radioactive contamination.

The Department of Energy’s Office of Environmental Management and the New Mexico Environment Department (NMED) have negotiated a settlement on terms to renew the 10-year operating permit for the Waste Isolation Pilot Plant near Carlsbad, N.M. The DOE, along with WIPP’s operating contractor, Salado Isolation Mining Contractors, and the NMED negotiated the settlement with New Mexico stakeholders.

Nuclear Waste Services, the United Kingdom’s radioactive waste management organization, launched in January 2022, has begun a wide range of studies to evaluate sites that could be suitable to host a geological disposal facility (GDF).

Having deemed the application admissible, France’s nuclear safety authority, Autorité de sûreté nucléaire (ASN), will undertake a technical appraisal of Andra’s application to construct the Cigéo deep geological disposal facility for radioactive waste.

The Nuclear Regulatory Commission is issuing for public comment draft guidance on the use of decommissioning trust funds for the disposal of major radioactive components from nuclear power plants that are still in operation.

The question “What about the waste?” is typically thrown out by the antinuclear crowd as an attempt to bog down the discussion of nuclear development. However, with renewed interest in nuclear power—and new advanced reactors in particular—what to do about used nuclear fuel is coming to the fore as a question that needs resolving.

American Nuclear Society Executive Director/Chief Executive Officer Craig Piercy responded to the Department of Energy’s awarding the Society about $2 million to lead a team of universities in developing a replicable model for community engagement on nuclear storage, saying the work will help the DOE determine what consensus decision-making looks like in the siting process for facilities storing commercial spent nuclear fuel and high-level radioactive waste.

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.
