Waste Management

International Atomic Energy Agency director general Rafael Mariano Grossi visited Japan’s Fukushima Daiichi site on February 19, where he joined scientists from the Third Institute of Oceanography in China, the Korean Institute for Nuclear Safety in South Korea, and the Spiez Laboratory in Switzerland in collecting seawater samples from a boat near the damaged nuclear power plant.

A team with the Department of Energy’s Idaho Cleanup Project successfully tested robotic equipment being developed to retrieve radioactive calcine, a granular solid waste, at the Idaho National Laboratory Site, the DOE’s Office of Environmental Management has announced.

The Department of Energy’s Office of Environmental Management said it has reached a regulatory milestone ahead of schedule in preparing radioactive waste tanks for closure at the Savannah River Site in South Carolina. DOE-EM said it received concurrence in January from the South Carolina Department of Environmental Services (SCDES) and the U.S. Environmental Protection Agency that SRS had successfully removed waste from the site’s Tank 4 and may now proceed to waste sampling and analysis of that tank ahead of its closure.

The U.K. government’s Nuclear Waste Services said it has identified three “areas of focus” in its search to find a suitable site and a willing community to host a geologic disposal facility (GDF) for the country’s most hazardous radioactive waste. The areas are within three communities currently involved in the siting process—Mid Copeland and South Copeland in Cumbria, and East Lincolnshire, England.

Finland’s Radiation and Nuclear Safety Authority (STUK) stated that if everything goes well, it can complete the assessment of the operating license for the country’s deep geologic repository for spent nuclear fuel “well before the end of the year.”

A flurry of amicus briefs from states, politicians, and special interest groups were filed with the U.S. Supreme Court this week, urging the court to uphold a 5th Circuit Court of Appeals ruling that invalidated Interim Storage Partners' license for a consolidated interim storage facility for commercial spent nuclear fuel in Andrews County, Texas.

A recent Bulletin of the Atomic Scientists article cautions that uncertainty regarding the management of wastes generated by small and advanced reactors could drive up costs, making them uncompetitive with existing light water reactor technology.

The Swedish Nuclear Fuel and Waste Management Company (Svensk Kärnbränslehantering AB, or SKB) broke ground on its spent nuclear fuel repository near the Forsmark nuclear power plant on January 15. SKB, which is owned by Sweden’s nuclear power plants, expects the final repository will be ready for disposal in the 2030s, and will be fully extended in the 2080s.

I’ve been reflecting on the recent American Nuclear Society Winter Conference and Expo, where I enjoyed the discussion on recycling used nuclear fuel to recover valuable minerals or products for future applications. I have spent more than 30 years focusing on dissolving and separating nuclear material, so it was refreshing to hear the case for new applications being made. However, I feel that these discussions could go further still.

Radiation is energy, something that our society seems to have an endless need for. A nuclear power station produces a lot of radiation that is mostly discarded. But once fuel has been used, it still produces significant levels of radiation and heat energy. The associated storage, processing, and eventual disposal of this used fuel requires careful management and investment to protect systems and people from the radiation. Should we really disregard—and discard—this energy source, along with all the valuable minerals in the used fuel, when we could instead use it to deliver significant value to society?

Nuclear energy produces about 9 percent of the world’s electricity and 19 percent of the electricity in the United States, which has 94 operating commercial nuclear reactors with a capacity of just under 97 gigawatts-electric. Each reactor replaces a portion of its nuclear fuel every 18 to 24 months. Once removed from the reactor, this spent (or used) nuclear fuel (SNF or UNF) is stored in a spent fuel pool (SFP) for a few years then transferred to dry storage.

The Department of Energy has agreed to hold a 30-day review and comment period on a draft environmental analysis associated with a proposed plan for retrieving, grouting, and transporting some of Hanford’s low-activity tank waste for out-of-state disposal.

The National Nuclear Security Administration’s strategy for managing nuclear waste from nuclear weapons maintenance and modernization activities is not comprehensive and does not fully address all statutory requirements, according to a report by the Government Accountability Office.

Legislation that aims to leverage the best available science and technology of U.S. national laboratories to support the cleanup of legacy nuclear waste has been introduced in the Senate by Sen. Ben Ray Luján (D., N.M.).

The Combining Laboratory Expertise to Accelerate Novel Solutions for Minimizing Accumulated Radioactive Toxins (CLEAN SMART) Act, introduced on December 12, would codify and fund the Department of Energy to accelerate the development, demonstration, and deployment of breakthrough technologies and innovations for nuclear waste cleanup.

Legacy waste: Currently, the DOE’s Office of Environmental Management is responsible for the remediation of 15 legacy sites across the United States that hold nuclear waste from the Manhattan Project and the Cold War era. According to Luján, the cost to decommission these remaining sites continues to grow and is estimated to be nearly $700 billion, for a completion date near the end of the century.

The Department of Energy’s Oak Ridge Office of Environmental Management (OREM) and contractor United Cleanup Oak Ridge (UCOR) have finished fieldwork and have begun monitoring groundwater elevations for a study at the Environmental Management Disposal Facility (EMDF) project site in Tennessee.

Finland’s regulatory authority, the Radiation and Nuclear Safety Authority (STUK), announced that it was further delaying issuing a statement on the safety case for the Onkalo spent nuclear fuel repository until 2025, saying that Posiva’s license application material is not yet ready.

While the United States was celebrating Thanksgiving Day, Canada’s Nuclear Waste Management Organization (NWMO) announced that it has selected a site in northwestern Ontario for a deep geologic repository to hold the country’s spent nuclear fuel

DeepGeo, a Rhode Island–based company seeking to develop multinational spent nuclear fuel repositories, and Denmark-based thorium reactor developer Copenhagen Atomics have signed a collaboration agreement that will see the companies work together on the management of nuclear fuels and waste streams associated with a thorium breeder reactor.

As of last week, crews with Department of Energy cleanup contractor Idaho Environmental Coalition (IEC) processed more than 142,000 gallons of radioactive sodium-bearing tank waste at Idaho’s Integrated Waste Treatment Unit (IWTU) this year.

The Department of Energy’s estimated overall liability for failing to dispose of the country’s commercial spent nuclear fuel jumped as much as 10 percent this year, from a range of $34.1 billion to $41 billion in 2023 to a range of $37.6 billion to $44.5 billion in 2024, according to a financial audit of the DOE’s Nuclear Waste Fund (NWF) for fiscal year 2024.

The Solid Waste Management Facility (SWMF) at the Savannah River Site saw a large reduction of transuranic (TRU) waste in fiscal year 2024, achieving the highest volume of TRU waste shipped out of state by the facility in the past 10 years, according to the Department of Energy.

TRU waste typically consists of protective clothing, tools, rags, equipment, and miscellaneous items contaminated with small amounts of plutonium and other heavy elements.
