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.

Each year, more than 60,000 middle schoolers throughout the country participate in DiscoverE’s Future City Competition, which asks students to tackle pressing real-world issues through the lens of urban design and engineering. At this year’s Future City Finals Awards Ceremony in Washington, D.C., on February 20, the American Nuclear Society presented the award for Best Use of Nuclear Science.

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.

Mark your calendar and get your name in the books for two exciting conferences coming up in the second half of the year: the 26th Technology of Fusion Energy Meeting (TOFE 2024) and Plutonium Futures—The Science 2024.

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.

The Department of Energy’s Office of Environmental Management announced that its Office of River Protection (ORP) recently created a plan with contractor Bechtel National for completing the High-Level Waste Facility at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant.

The Diversity and Inclusion in ANS Committee on May 9 hosted a webinar titled “Our nuclear family: Empowering parents and caregivers in the nuclear industry.” The speakers, who are parents and caregivers as well as nuclear industry professionals, highlighted how the nuclear industry supports caregivers facing life transitions or focusing on parental responsibilities. They also discussed challenges and areas where the industry has room for improvement in supporting caregivers. Some of the panelists have made their own contributions to fostering inclusiveness for caregivers in the industry.

The full webinar is available for anyone to view online at ans.org/webinars/view-family24/.

The Defense Nuclear Facilities Safety Board (DNFSB), an independent government organization responsible for overseeing public health and safety issues at Department of Energy defense nuclear facilities, has alerted the DOE because of safety concerns it has regarding the use of continuous air monitors (CAM) at the Waste Isolation Pilot Plant in New Mexico.

Part of WIPP’s new Safety Significant Confinement Ventilation System (SSCVS), the CAM system is intended to detect a radiological release in the repository and automatically close vent dampers to prevent the escape of radioactive particles to the outside environment. The SSCVS, which began commissioning in November 2023, is intended to increase airflow to the underground to allow for simultaneous underground waste emplacement, mining, and ground control work.

BWX Technologies has partnered with the American Nuclear Society to offer customized ANS Nuclear Ambassadors training to BWXT employees. The training kicked off in February with an initial two-hour virtual event that was presented to more than 60 BWXT employees, and it wrapped in April.

BWXT is the first company to participate in ANS’s newly revamped curriculum, which trains experts in K-12 learning.

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.

Department of Energy cleanup contractor Savannah River Mission Completion (SRMC) has garnered national recognition for its commitment to safety, recently receiving three awards from the National Safety Council: the Occupational Excellence Award, the Perfect Record Award, and the Superior Safety Performance Award.

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.
