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.

In March 1949, the Atomic Energy Commission selected a site in Idaho for the National Reactor Testing Station (NRTS), known today as Idaho National Laboratory. Idaho’s Snake River Plain was selected because of the rural nature of southern Idaho. The site would go on to be the most remarkable proving ground for today’s nuclear industry. Experiments at this world-class facility have continually paved the way for nuclear innovation.

Already for the second time this year, Southern Company has announced a delay to the expected commercial operation of Unit 3 at the Vogtle nuclear plant’s two-unit construction site. In addition, a delay to Unit 4’s startup is also possible, Southern said.

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.

Commonwealth Fusion Systems (CFS) hosted visiting officials for a tour and ribbon-cutting ceremony to officially open its new headquarters in Devens, Mass., on February 10. Energy secretary Jennifer Granholm, Sen. Elizabeth Warren (D., Mass.), and Sen. Edward Markey (D., Mass.) were among the national, state, and local leaders invited to celebrate what CFS heralded as a “fusion energy campus.”

Two large tanks near the Effluent Treatment Facility (ETF) at the Department of Energy’s Hanford Site in Washington state were removed recently to make way for future wastewater treatment activities at the ETF.

As if being stuck in the middle of a combat zone isn’t sufficiently nerve-racking, workers at Ukraine’s Zaporizhzhia nuclear power plant—under Russian occupation since last March—must now concern themselves with having access to enough water to keep the facility safe.

In remote southeastern Washington you will find the sprawling Hanford Site, which was constructed to produce plutonium for the Manhattan Project. Within this complex is the first plutonium production reactor, the Hanford B Reactor. The DuPont Corporation was responsible for construction and operation of the B Reactor. Due to the urgency of the Manhattan Project, construction was completed in just over a year, and The B Reactor went critical on September 26, 1944. After the needs of the Manhattan Project were satisfied, the reactor was briefly shut down and then restarted to produce plutonium for roughly another 20 years, supporting Cold War efforts. In addition to plutonium production, the B Reactor also pioneered the process to produce tritium for the first-ever thermonuclear test.
