Published since 1959, Nuclear News is recognized worldwide as the flagship trade publication for the nuclear community. News reports cover plant operations, maintenance and security; policy and legislation; international developments; waste management and fuel; and business and contract award news.
The Nuclear Regulatory Commission has notified TerraPower that the company has delivered enough information on volcanic risk activity around its proposed small modular reactor project in Kemmemer, Wyo., to satisfy the federal review process.
The Department of Energy’s Office of Nuclear Energy announced on September 24 four new GAIN vouchers. GAIN—the Gateway for Accelerated Innovation in Nuclear—selected four companies to receive vouchers to advance microreactor technologies, identify potential sites capable of hosting a nuclear-powered data center, and prevent corrosion in molten salt reactors.
Hours before the Senate Committee on Environment and Natural Resources (ENR) opened a scheduled September 19 hearing on fusion energy technology development, CNN published an article titled “The US led on nuclear fusion for decades. Now China is in a position to win the race.” The article was entered into the hearing record, but senators had already gotten the message.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) is seeking qualified candidates for two open positions. The ACRS is the world’s oldest organization devoted to reactor safety and is statutorily mandated by the Atomic Energy Act of 1954, as amended. Today, the ACRS reports directly to the NRC’s commission and provides an independent expert technical review of and advice on matters related to the safety of existing and proposed nuclear facilities and on the adequacy of proposed reactor safety standards. The ACRS also advises the commission on health physics, radiation protection, and nuclear waste disposal facility issues.
The ACRS is a part-time advisory group consisting of a maximum of 15 members who are well-recognized experts in technical areas that are key to nuclear safety and whose membership represents a diverse breadth of experience in all aspects of the nuclear enterprise: industry, universities, national laboratories, and government.
The U.S. Department of Energy’s National Nuclear Security Administration and Romania’s National Commission for Nuclear Activities Control (CNCAN) recently celebrated 15 years of collaboration in advancing radiological security.
Ontario Power Generation’s expansive refurbishment project on its four 878-MWe CANDU units at the Darlington nuclear power plant is proceeding faster than expected, OPG announced on September 17.
Westinghouse Electric Company has completed the front-end engineering and experiment design (FEEED) for a prototype microreactor at Idaho National Laboratory, the Department of Energy recently announced. The one-fifth scale version of eVinci, Westinghouse’s 5-MWe sodium-cooled heat pipe design, is one of three reactors that could be tested at the National Reactor Innovation Center’s (NRIC) DOME test bed “as early as 2026,” the DOE said.
Eleven countries have been newly elected to serve on the International Atomic Energy Agency’s 35-member Board of Governors for the 2024–2025 term. The election took place on September 19 at the plenary session of the 68th IAEA General Conference.
Nuclear powerhouse Constellation announced today the signing of a 20-year power purchase agreement with Microsoft that will pave the way for the restart of Three Mile Island Unit 1—under a new name to honor Chris Crane, former chief executive of Exelon when Constellation was part of the larger company.
The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of Turkey Point nuclear power plant's Units 3 and 4 subsequent license renewals (SLRs) to July 19, 2052, and April 10, 2053, respectively.
Nuclear science and technology is uniquely positioned to be a gateway for curiosity and exploration for students in grades K–12. Its study examines the literal fabric of reality, it has applications from the tiniest to the grandest of scales. It’s a constantly evolving industry with a bright future of discoveries and new technologies, and it’s an essential factor in our global effort to reduce carbon emissions and transition to cleaner energy sources. Frankly, learning about and doing things with atoms is pretty cool, from a kid’s perspective.
The U.S. Attorney’s Office in Massachusetts announced criminal charges this week against two men for allegedly smuggling and conspiring to violate export controls relating to the sale of laser equipment to the Russian nuclear industry.
Microreactor developer Aalo Atomics and municipal electric utility Idaho Falls Power have developed a memorandum of understanding that could lead to the siting of seven sodium-cooled microreactors and a power purchase agreement for Idaho Falls.
The Department of Energy has released a notice of a funding opportunity (DE-FOA-0003422) for the department’s Office of Environmental Management Minority Serving Institutions Partnership Program (MSIPP). With an estimated value of $15.5 million, the funding opportunity is a set-aside for minority-serving institutions (MSIs) and will result in multiple financial assistance awards ranging from one year to three years in length.
I really think so. Especially after visiting Abilene Christian University’s new Dillard Science and Engineering Research Center, the home of the Nuclear Energy Experimental Testing (NEXT) Lab and where the university will test its new molten salt research reactor design. The visit was part of the 12th Thorium Energy Alliance Conference. NEXT Lab director and program manager Rusty Towell anticipates that the research reactor will be operational in two years, and I believe it will. What was most impressive is that the reactor is suited to be scaled to any size from small to large—a key feature in any decarbonized world.
The Nuclear Regulatory Commission issued a construction permit yesterday to Abilene Christian University, giving ACU and its partners the go-ahead to build the Molten Salt Research Reactor (MSRR) facility on its Abilene, Texas, campus. The 1-MWt research reactor is the first molten salt–fueled reactor to get a construction permit from the NRC. After Kairos Power’s Hermes, it is the second non–light water reactor construction permit issued by the NRC.
New research into the dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt—a potential fuel for molten salt reactors—has been published in the Journal of the American Chemical Society. A recent news release from Oak Ridge National Laboratory describes how researchers from ORNL, Argonne National Laboratory, and the University of South Carolina used ORNL’s Spallation Neutron Source (SNS) to document the unique chemistry of liquid UCl3 “for the first time.”
Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.
The U.S. Nuclear Regulatory Commission began a special inspection last week at South Texas Project nuclear power plant into two incidents at the site, which led to separate, unplanned shutdowns of both Units 1 and 2.
The recent decision by the U.S. Supreme Court to overturn the Chevron doctrine marks a significant shift in the landscape of federal decision-making. For more than 40 years, this doctrine has provided a framework wherein courts deferred to federal agencies’ interpretations of ambiguous laws in recognition of the specialized expertise these agencies bring to policy and regulatory development.
