Spoiler alert: America has one more nuclear reactor on line.
It’s been a long, hard slog for the Vogtle reactor expansion project, and the news coverage has been tough. I would describe it as the “standard media fare” of late—a steady flow of click-inducing “breaking news” alerts on cost overruns and schedule delays. Sure, it’s all fair game in a world with press freedom, but I had hoped for more substance along with the “horse race” reporting from our Fourth Estate.
Nuclear is hard—but it’s not just nuclear. In the United States, big groundbreaking projects of all sorts veer over budget and behind schedule frequently these days, resulting in unpleasant headlines along the way. Then, when they are up and running, these facilities tend to fall out of the public spotlight, and we all start taking them for granted. But this narrative arc hides a larger truth. When Vogtle Unit 4 joins Unit 3 in commercial operation later this year, the two units together are tipped to churn out over 17 million megawatt-hours of steady 24/7 power on an annual basis. That’s more energy per year than all the windmills in California—enough to feed one million homes and businesses. It will do this for the next 60, 80, maybe even 100 years. Talk about a buried lede!
China is on pace to add as many as 10 reactors a year and may surpass the United States’ total nuclear capacity by 2030.
As part of this growth, construction is wrapping up this month on the world’s first onshore commercial modular pressurized water reactor—Linglong One, which is located in the Hainan province. That’s according to China Metallurgical News, an established news unit reporting on China’s industrial chain.
The U.S. Nuclear Regulatory Commission hosted a public meeting earlier this month for community members to learn more about X-energy’s plans to build small modular reactors at a Dow Chemical plant on the Gulf Coast of Texas.
Bulgaria has shortlisted South Korea’s Hyundai Engineering and Construction team to build new reactors at Kozloduy nuclear power plant.
Of the five international companies to bid on the project, Hyundai E&C was the only one that met the requirements of project company Kozloduy NPP—New Builds Plc. for the commissioning and construction of two new Westinghouse Electric AP1000 reactors, the Bulgarian firm said. Bids were due February 2.
The long-awaited fourth unit at Plant Vogtle has hit another delay.
Atlanta-based Southern Co. announced last week that vibrations in the cooling system in Unit 4 require additional work that will push the reactor’s start date from the first quarter this year to the second quarter. The company said the problem is already fixed, but there is too much additional testing needed to meet a first quarter deadline.
Nuclear Safety Design Criteria and Functional Performance Requirements for Liquid-Fuel Molten Salt Reactor Nuclear Power Plants (ANSI/ANS-20.2-2023) has just been issued and is now available for purchase. It was developed by the American Nuclear Society and received approval from the American National Standards Institute (ANSI) on January 4.
The United Kingdom’s Future Nuclear Enabling Fund (FNEF) awarded £33.6 million (about U.S.$42.8 million) to GE Hitachi Nuclear Energy last week.
The move comes as part of the FNEF’s support for growing the Britain’s generation of 24 GW of nuclear by 2050. The country currently produces around 9,100 megawatts per year.
Ukraine plans to start construction on four new nuclear plants this summer or fall, the country’s energy minister said in televised remarks today.
The quicker timeline aims to compensate Ukraine for lost energy capacity as its war with Russia continues. Ukraine’s government, however, still needs to sign off on the plans.
“We need vessels,” said energy minister German Galushchenko.
Wesoff
According to an admittedly informal and unscientific survey of people from online “nuclear affinity groups” conducted by Eric Wesoff, the editorial director for clean energy newsroom Canary Media, there is no consensus regarding when the next nuclear power plant will come on line in the United States. Wesoff recently reported that upon polling his nuclear-connected network on LinkedIn, X, and Reddit, he found that “the responses were all over the map.”
Nuclear renaissance? Wesoff was prompted to try his survey about the expected date for the next nuclear plant because “conditions are perfect for the American nuclear renaissance.” He cited strong support for the nuclear industry from the Department of Energy as well as from public opinion polls and online “influencers.” He thought therefore that he would find confident predictions for when the next new U.S. reactor would go on line. Instead, he found uncertainty and varied responses.
This article is the first in a series that will examine the history of small modular reactors.
Small and medium reactors have been an integral part of the U.S. nuclear power enterprise since the early days of the industry. Many of the designs for the next generation of reactors are rooted in the designs of the 1950s and ’60s, but the development and push for deployment have gained momentum only within the last decade.
This recent momentum led a reader of Nuclear News to suggest an article reviewing the history of small modular reactors. NN staff jumped on this idea, deciding a series of articles would do better justice to such a complex and interesting topic.

The BWRX-300 is the 10th generation of boiling water reactor designed by GE Hitachi and has a number of evolutionary features. We learned from the design of the Economic Simplified Boiling Water Reactor (ESBWR), the BWRX-300’s predecessor, that implementation of a plant design that utilizes passive safety features can result in a relatively large containment. From the inception of the BWRX-300, our goal was simplification of the design and the reduction in overall size of the “safety footprint,” which includes both containment and the safety-related--component plant areas. The design team was empowered to consider any and all simplification efforts, which were evaluated by the GEH team. One key to implementing this goal—design of a plant that can be licensed anywhere in the world—is the use of a probabilistic risk assessment (PRA) that helps ensure the resulting plant risk is low.
The Advanced Reactor Codes and Standards Collaborative (ARCSC) held its second workshop on November 30, 2023, in Washington, D.C. The hybrid event had just over 200 participants, including representatives from standards development organizations (SDOs), the Electric Power Research Institute, the Nuclear Energy Institute, national laboratories, government agencies, vendors, advanced reactor designers, and consultants as well as representatives from other U.S. industry and international organizations, including the International Atomic Energy Agency. ANS Standards Board chair Andrew Sowder, senior technical executive at EPRI, welcomed attendees to EPRI’s offices, where the workshop was held.
The Gateway for Accelerated Innovation in Nuclear (GAIN) announced December 19 that seven firms will get vouchers to access the nuclear research facilities and expertise of the national laboratory complex in the first round of fiscal year awards. Each company is paired with one or more national laboratories to work on concepts from advanced reactor fueling to fuel recycling to climate forecasting.
