Subsequent license renewal (SLR) authorizes nuclear power plants to operate for an additional 20 years beyond the 60 years of the initial license (years 1–40) and the first license renewal (years 41–60). NUREG-2191, Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR), and NUREG-2192, Standard Review Plan for Review of Subsequent License Renewal Applications (SRP-SLR), were issued in July 2017 and provide guidance for generic evaluation of plant aging management programs and reviews of SLR applications, respectively, by Nuclear Regulatory Commission staff.
The first SLR application was submitted to the NRC for review in January 2018. A total of 10 additional SLR applications addressing 20 operating units have been submitted to the NRC. Nine operating units have been approved by the NRC, and 13 units are under review. These 22 units do not have any issues, including operating experience issues, precluding them from achieving a renewed license.

This month’s Nuclear News pays tribute to the people and projects that keep our nuclear power plants running.
In the nuclear industry, “life extension” is a venerable term that broadly describes the care required to sustain the safe and efficient operation of large, complex energy generation facilities for decades to come, some of which you will read about in these pages.
Of late, however, the general concept of life extension has also taken a firmer hold in our societal consciousness.
Whether we absorb it from Instagram videos about some Silicon Valley techie’s quest for immortality or sense it in one of the thousands of dryly written journal articles documenting our increasing ability to control and change life at the molecular level, the promise of extended life and health has universal appeal—and it’s never seemed more within reach than it does right now.
In the high-stakes world of power generation, ensuring continuous operation and reducing downtime are central priorities. With the increasing complexity of power generation systems, maintenance practices are evolving to meet these demands more efficiently. Understanding the roles of Predictive Maintenance (PdM), Preventive Maintenance (PM), and Reactive Maintenance (Run-to-Failure) is crucial for maintenance professionals in the energy sector to make informed decisions about equipment management and long-term operational strategy.

Global partnerships advance the nuclear enterprise, demonstrating commitment to energy security, supply chain buildout, and economic and human development. Collaborations remain imperative, keeping these things in mind:
Approximately half of the 400-GW reactor fleet will be retiring by 2040.1
The forecasted need for new nuclear is 300–600 GW by 2050.
There is a need to counter the build-own-operate model.2
Appropriate funding and financing mechanisms are needed.
Host country regulatory oversight is paramount.
By 2050, there will be 4 million nuclear professionals supporting the industry.3
Here is a recap of industry happenings from the recent past:
Texas universities evaluating SMRs for water desalination
Natura Resources has signed a memorandum of understanding with two Texas universities—Texas Tech University and Abilene Christian University—to evaluate the integration of the company’s molten salt small modular reactor technology with water desalination systems. The collaboration includes Texas Tech’s Texas Produced Water Consortium, which was established by the Texas legislature in 2021 to explore the potential benefits of using treated produced water for purposes outside of the oil and gas industry of the Permian Basin. Produced water is salty or brackish hydrocarbon-containing water that is produced as a byproduct of oil and gas extraction. The stated goal of the new collaboration is to develop “a sustainable solution for water scarcity by purifying produced water from oil and gas operations, making it available for agricultural and other beneficial uses.” Abilene Christian University is planning to host the first deployment of Natura Resources’ Natura MSR-1, a 1-MWt molten salt research reactor.

As Western countries accelerate their decarbonization efforts, nuclear power is set to play a key role in achieving net-zero emissions by 2050. For instance, the United Kingdom’s goal of expanding nuclear capacity to 24 gigawatts by mid-century, meeting 25 percent of projected electricity demand, highlights the need for reliable, low-carbon energy sources. As the world’s top uranium producer, Kazakhstan is poised to be a vital partner in this transition, supplying the fuel that powers nuclear reactors and supports the U.K.’s and other Western countries’ clean energy goals.
At COP28 in 2023, the International Atomic Energy Agency emphasized the urgent need to accelerate deployment of nuclear power to achieve net-zero carbon emissions. This sentiment was reinforced the following year at COP29, where 31 countries committed to tripling nuclear capacity by 2050 to meet global climate goals. These developments highlight the growing recognition of nuclear energy’s role in providing reliable, low-carbon power essential for a sustainable future.

Shaping the global nuclear future requires an understanding of nuclear’s role in addressing national and energy security endeavors together with foresight into the energy sector’s future needs. Nuclear typically produces reliable baseload electricity, but it could also play an important role in economically viable cogeneration. In addition, future electricity demand will require significant enhancements to baseload generation. Addressing these challenges requires a combination of innovation, collaboration, capacity enhancements, and focused strategic investments.
Nuclear is increasingly recognized as essential to enabling energy security and achieving net-zero emissions. The United Kingdom has demonstrated leadership in this area, with initiatives such as the Young Generation Network’s global #NetZeroNeedsNuclear campaign at COP26 in Glasgow, Scotland. Efforts like these are impossible without international collaboration.
Patrick Fragman, Westinghouse’s chief executive, said in a recent interview with Politico that the U.S. and Europe are still ideal partners on nuclear power.
Even though President Trump’s latest policy moves are straining some U.S. relations with nations, “Westinghouse stresses it’s a private company that is now Canadian-owned—and that nuclear projects function on a time scale that extends beyond politicians,” Fragman told Politico.

I find myself saying the expression above a lot these days—to my kids, my wife, my friends, and colleagues. Most recently, I said it to the person sitting next to me after the pilot of our plane—bound for Reagan National Airport a day after the collision of AA flight 5342 and a military Blackhawk helicopter—aborted the landing at the last minute.
I am not sure where I picked up this pronouncement, but I find it to be apropos to the topsy-turvy moment where we find ourselves in 2025. In addition to the first U.S. commercial airline crash in 15 years, we are witnessing a new presidential administration in its infancy playing by the Silicon Valley rules of “move fast, break things.” We’ve seen DeepSeek, the low-cost Chinese AI that reportedly uses 50–75 percent less energy than its NVIDIA-powered counterparts, tank Constellation’s market value by more than 20 percent in one late-January trading day.
Here is a recap of industry happenings from the recent past:
BWRX-300 SMR deployment partnership developed
Several U.S. utility companies and supply chain partners have formed a coalition to accelerate deployment of GE Hitachi Nuclear Energy’s BWRX-300 small modular reactor. The coalition, which has applied for $800 million in funding from the Department of Energy’s Generation III+ SMR program, is led by the Tennessee Valley Authority and includes GEH, Bechtel, BWX Technologies, Duke Energy, Electric Power Research Institute, Indiana Michigan Power, Oak Ridge Associated Universities, Sargent & Lundy, Scot Forge, other utilities and advanced nuclear project developers, and the State of Tennessee. TVA previously selected the BWRX-300 SMR for possible deployment at the Clinch River site, near Oak Ridge, Tenn. If the new coalition is awarded the requested DOE funding, TVA intends to accelerate construction of the first SMR at this site by two years, planning for commercial operation by 2033.
The International Atomic Energy Agency’s International Nuclear Information System (INIS) has increased its user friendliness and knowledge expanse by incorporating Invenio, an open-source platform developed by the European Organization for Nuclear Research.
Aiming to deploy the nation's first small modular reactor, TerraPower has announced contracts for the final long-lead items needed for its Natrium unit, currently under construction in Wyoming.
The Nuclear Regulatory Commission has published its 2024–2025 Information Digest, NUREG-1350, Vol. 35, which describes the agency’s responsibilities and activities and provides general information regarding nuclear-related topics.
According to the NRC, the digest is intended to be a quick reference with important facts about the NRC and the industry it regulates presented publicly in an “easy-to-understand format” with visual aids.
The NRC published the digest annually from 1989 until 2023, when the agency switched to a two-year publication cycle. The next digest containing updated data will be published in February 2027.
Indian Prime Minister Narendra Modi met with President Trump last week and agreed to a new initiative to drive “transformative change across key pillars of cooperation” between the two countries.

Mission of Gen IV International Forum is extended
A framework agreement to continue the Generation IV International Forum (GIF) beyond its scheduled February 2025 expiration was signed by representatives of the United States and the United Kingdom at November’s COP29 meeting in Azerbaijan. The new agreement, which excludes previous signatory Russia, focuses on the sharing of information and pooling of funds for advanced nuclear technologies. The agreement also sets a goal of deploying fourth-generation nuclear technology by 2030. The specific advanced technologies identified by the forum are gas-cooled fast reactors, lead-cooled fast reactors, molten salt reactors, sodium-cooled fast reactors, supercritical water–cooled reactors, and very-high-temperature reactors.
From lifting moratoriums to launching studies to labeling it as clean, state lawmakers are exploring ways to give nuclear energy a boost in 2025. Here’s a look at some of the pronuclear legislation under review.
The Tennessee Valley Authority announced last week the selection of several partners—Bechtel, Sargent & Lundy, and GE Hitachi—to advance plans for what the company hopes will be its first small modular reactor project at its Clinch River site.
Wright
Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.
During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”
The U.S. departments of Energy and State have signed a memorandum of understanding with the Republic of Korea’s ministries of Trade, Industry and Energy and of Foreign Affairs for the two nations to partner on nuclear exports and cooperation.
