The U.S. Nuclear Regulatory Commission has formally accepted TerraPower’s small modular reactor construction permit application and is scheduling it for review.

The company’s Natrium reactor demonstration project—the nation’s first commercial advanced reactor of its kind—would be built on land in Wyoming near one of the state’s retiring coal plants. Kemmerer Power Station Unit 1 would operate as a 345-MW sodium-cooled reactor in conjunction with molten salt–based energy storage.

On the company’s earnings call this month, Constellation CEO Joe Dominguez was asked if there is a possibility of restarting the shuttered Three Mile Island plant—as is being proposed for the Palisades nuclear plant in Michigan.

“We’re not unaware that opportunity exists for us,” Dominguez said. “We’re obviously seen what’s happened with Palisades and I think that was brilliant. Brilliant for the nation. … We are doing a good bit of thinking about a number of different opportunities, and that would probably certainly be one of those that we would think about.”

Japan’s Kyoto Fusioneering, a fusion startup spun out from Kyoto University, and Canadian Nuclear Laboratories have announced the formation of Fusion Fuel Cycles Inc., headquartered in Chalk River, Ontario, Canada. The joint venture extends a strategic alliance formed between the two entities in September 2023 and aims to develop and deploy deuterium-tritium (D-T) fusion fuel cycle technologies.

Idaho’s nuclear energy history is deep and rich. The National Reactor Testing Station (NRTS) began its history as an artillery testing range in the 1940s.¹ Following World War II, Walter Zinn, Argonne National Laboratory’s founding director and Manhattan Project Chicago Pile-1 project manager, proposed to the Atomic Energy Commission that a remote location be found for building test reactors. In 1949, he and Roger S. Warner, AEC’s director of engineering,² developed a list of potential sites from which the NRTS was selected. Over the decades, quite a few companies and AEC national laboratories built 52 experimental and test reactors at the NRTS, including 14 by Argonne.³ (For a brief AEC video on the NRTS, see youtube.com/watch?v=C458NsH08TI.)

During the International Atomic Energy Agency’s International Conference on Nuclear Security this week, leaders from the U.S. Department of Energy’s National Nuclear Security Administration and the European Commission made a joint statement on enhancing radioactive source security.

Last week Tennessee Gov. Bill Lee and Stuart McWhorter, commissioner of the state’s Department of Economic and Community Development, announced that the University of Tennessee–Knoxville and Roane State Community College will receive funding from Tennessee’s Nuclear Energy Fund to support existing nuclear programs as well as develop and implement new nuclear education curriculum.

Using its portion of the $50 million Nuclear Energy Fund, the University of Tennessee will establish a new program for non-nuclear engineers to obtain a minor in nuclear engineering at its Knoxville campus. Separate funding for Roane State Community College will allow purchase of laboratory equipment for that school’s inaugural nuclear technology program, which launches in the fall of 2024.

The Nuclear Regulatory Commission hosted a public meeting yesterday to gather comments on its web-based ADAMS (WBA) system—a public document search tool introduced in 2010. It’s a tool that novice users find daunting and frequent users find frustrating, whether they’re searching for a single document or for thousands of documents on a single topic.

Members of the U.S. Senate Energy and Natural Resources Committee on Tuesday included nuclear energy as part of their discussions of the increasing demand for electricity anticipated in the coming decade, spurred in large part by the rise of artificial intelligence, data centers, and public consumption.

Last year, 168 incidents of illegal or unauthorized activities involving nuclear and other radioactive materials were reported to the International Atomic Energy Agency’s Incident and Trafficking Database (ITDB). According to the agency, this number is in line with historical averages. These incidents were reported by 31 IAEA member states; as of 2023, a total of 145 member states have participated in the ITDB.

There is a mix of good news and bad in the latest Nuclear Engineering Enrollment and Degrees Survey, 2021–2022 Data. According to this report from the Oak Ridge Institute for Science and Education (ORISE), compiled with data initially released in November 2023 and updated in February 2024, the number of doctoral degrees awarded in nuclear engineering at the end of the 2022 academic year in the United States—211 Ph.D.s—was the highest since the beginning of this survey’s data collection in 1966. However, the overall numbers of nuclear engineering degrees awarded in 2021 and 2022 were at their lowest levels in more than a decade. In addition, both undergraduate and graduate enrollment numbers were down compared with 2018 and 2019.

The Southeast Nuclear Council, an initiative of regional trade association E4 Carolinas, is holding a webinar from 9:00 to 10:00 a.m. (EDT) on May 23 on nuclear energy workforce development in the southeast United States.

Registration is required for the event.

The Nuclear Regulatory Commission is issuing a final rule and corresponding update to the generic environmental impact statement (GEIS) the agency uses when considering applications to renew the operating licenses of nuclear power reactors. All four current NRC commissioners voted to approve the rule on May 16.

Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The Nuclear Regulatory Commission is holding a webinar on May 21 to get public input on how the Agencywide Documents Access and Management System—known as ADAMS—is working for the public.

Fast reactor developer Oklo, which recently went public on the New York Stock Exchange, announced on May 13 that it has signed a memorandum of understanding with Atomic Alchemy to cooperate on the production of radioisotopes for medical, energy, industry, and science applications.

Four minority-serving institutions (MSIs) have been named by the Nuclear Regulatory Commission as recipients of scholarship and fellowship grants worth a total value of $1.78 million.

On May 13, President Biden signed the Prohibiting Russian Uranium Imports Act, unlocking the $2.72 billion that Congress conditionally appropriated in March to increase production of low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU).

Nuclear Energy Institute president and CEO Maria Korsnick delivered her State of the Nuclear Energy Industry address at NEI’s 2024 Nuclear Energy Policy Forum yesterday. The forum this year is taking place May 14–16 in Washington, D.C., and serves to gather industry leaders, executives, and experts for pivotal conversations about the federal and state nuclear policy landscapes.

Korsnick updated attendees on policy priorities of the industry and gave her perspective on nuclear energy’s present and future.

She centered her talk on national and global priorities to secure a clean energy future at the same time as achieving energy independence and security—all while meeting a massive increase in demand for power. “Nuclear energy remains the key” to addressing these priorities, she said.

Radioactive materials are used in medical, research, and commercial facilities to treat cancer, irradiate blood, sterilize food and equipment, and build economies worldwide. In the wrong hands, however, even a small amount of radioactive material can do a great deal of harm. A radiological dispersal device (RDD), otherwise known as a “dirty bomb,” is believed to be an attractive weapon for terrorist groups due to its scale of impact—panic, physical contamination, costly remediation, and denial of access to facilities and locations.

The Department of Energy’s National Nuclear Security Administration Office of Radiological Security (ORS) enhances global security by preventing high-activity radioactive materials from being used in acts of terrorism. ORS implements its mission through three strategies: protecting radioactive sources used for vital medical, research, and commercial purposes by securing facilities that utilize radioactive isotopes; removing and disposing of disused sources; and encouraging the adoption and development of nonradioisotopic alternative technologies such as X-ray and electron beam irradiators.

This year marked the 50th anniversary of Waste Management Symposia’s Waste Management Conference, held March 10–14 in Phoenix, Ariz. The event has grown significantly since the first Waste Management Conference in 1974, which attracted about 200 attendees. This year’s conference saw a record attendance of around 3,300 people from more than 20 different countries and boasted 235 technical sessions and 89 exhibitors.
