The Government Accountability Office has recommended that the Department of Energy put a hold on construction of its High-Level Waste Facility at the Hanford Site near Richland, Wash. The GAO said design and construction of the facility, part of Hanford’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, should be paused until several actions are taken, including considering other alternatives for managing the site’s high-level radioactive liquid waste.

Report touts lessons from era of nuclear waste negotiator

September 20, 2024, 7:00AMRadwaste Solutions

As the Department of Energy embarks on its consent-based process for siting a geologic repository for spent nuclear fuel and high-level radioactive waste, a new report from the Center on Global Energy Policy at Columbia University SIPA highlights relevant lessons from the federal government’s now defunct Office of the Nuclear Waste Negotiator.

Established under Title IV of the Nuclear Waste Policy Act, the office, an independent agency within the executive branch, was primarily active from 1990 to 1995. Its role was to engage with state and tribal governments to find an acceptable and suitable host site for a repository.

The full report, Lessons from the Nuclear Waste Negotiator Era of the 1990s for Today’s Consent-Based Siting Efforts, is now available online. Its executive summary is available here.

ANS asks Congress to fund EPA work on repository standards

June 24, 2024, 7:00AMRadwaste Solutions

The American Nuclear Society brought together 11 other energy and environmental advocacy organizations in calling on Congress to fund the Environmental Protection Agency to develop a new, technology-neutral, generic environmental standard for the disposal of spent nuclear fuel and high-level radioactive waste in the United States.

In a letter to the leaders of the House and Senate appropriations committees, the groups ask for an additional $3 million in fiscal year 2025 for the EPA’s Office of Radiation and Indoor Air to work on the new standard.

Retrieval of nuclear waste canisters from a borehole

May 3, 2024, 9:31AMRadwaste SolutionsRod Baltzer

Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

The Department of Energy’s Office of Environmental Management is responsible for roughly 90 million gallons of radioactive liquid waste at Idaho National Laboratory, the Hanford Site in Washington state, and the Savannah River Site in South Carolina. About 900,000 gallons of waste are stored at INL, 56 million gallons at Hanford, and roughly 36 million at SRS. A further 400,000 gallons of waste from various operations are being stored at the Oak Ridge Site in Tennessee.

New Generic Repository Environmental Standards: Draft Recommendations from ANS

Used nuclear fuel and high-level radioactive wastes are by-products of nuclear energy production and other applications of nuclear technology, and the consensus approach to disposing of those wastes safely is to encapsulate them and emplace them in stable geologic formations (geologic repositories) where they will be isolated from people and the environment for very long periods of time. The federal government has established environmental standards for waste isolation that any proposed geologic repository must meet.

In July 2021, the American Nuclear Society established a special committee to consider possibilities for revised generic environmental standards for disposal of spent nuclear fuel and high-level radioactive waste in the United States. The committee developed a number of recommendations, which are contained in a draft report that was to be issued in February for review and comment by stakeholders. The draft report can be found on the ANS website, at ans.org/policy/repositorystandard/.

The committee’s draft recommendations are based on two underlying assumptions. First, that the relevant legislative framework for regulation defined in the Nuclear Waste Policy Act (NWPA) remains unchanged. Specifically, it is assumed that the Environmental Protection Agency will be charged with promulgating environmental standards for disposal and that the Nuclear Regulatory Commission will be charged with reviewing applications for disposal facilities using licensing requirements and criteria consistent with the EPA standards. Second, that existing generic disposal standards will be updated or replaced.

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.

A fateful day for nuclear waste policy: January 31, 1998

January 26, 2023, 3:12PMNuclear News

Next week will mark 25 years since January 31, 1998, a familiar date to most in the nuclear community, and revisited in today’s #ThrowbackThursday post with an article from the March 1998 issue of Nuclear News. “Those in the nuclear power industry are aware of the significance of the date January 31, 1998. ln the Nuclear Waste Policy Act of 1982, that date was set as the deadline for the U.S. government—more specifically, the Department of Energy—to begin taking possession of and responsibility for spent nuclear fuel from nuclear power plants nationwide” (NN, March 1998, p. 59).

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.

NWTRB releases updated report on national HLW programs

The Department of Energy has issued a request for proposals for the fabrication and testing of a prototype eight-axle railcar to carry the nation’s spent nuclear fuel and high-level radioactive waste. The heavy-duty, flat-deck railcar design known as “Fortis” received approval from the Association of American Railroads (AAR) in January 2021 to proceed to building and testing.

DOE affirms its interpretation of high-level waste

December 22, 2021, 12:00PMRadwaste Solutions

With a notice published in the December 21 Federal Register, the Department of Energy has affirmed its interpretation of the statutory term “high-level radioactive waste” to mean that not all wastes from the reprocessing of spent nuclear fuel are HLW. The DOE said it interprets the statutory term such that some reprocessing wastes may be classified as non-HLW and may be safely disposed of in accordance with its radiological characteristics.
