In my August column in Nuclear News, I reflected on the importance of ANS’s annual conferences for bringing together our nuclear community at the national level. In September, after speaking at Tennessee’s Nuclear Opportunities Workshop, I focused my NN column that month on the value of state-level conferences.

Also in September, alongside ANS Executive Director/CEO Craig Piercy, I shifted my focus to another key front in nuclear collaboration, the international stage, by attending the General Conference of the International Atomic Energy Agency in Vienna.

The timing of the IAEA’s General Conference could not have been better; it took place the same week the U.S. and U.K. kicked off a new wave of transatlantic partnerships in the nuclear sector between both government and industry. This fortuitous overlapping gave us a timely and concrete reminder of international collaboration’s unparalleled benefits.

The General Conference was an expectedly busy event. To cover as much ground as possible, Piercy and I took turns attending either the U.S. delegation meetings with other countries or the General Assembly of the IAEA, where the American Nuclear Society has a seat among other critical nongovernmental organizations.

We listened to presentations by several of the 180 IAEA member states, including, of course, the United States. Aside from ANS, the U.S. presence at the conference included U.S. Secretary of Energy Chris Wright, NRC Chair David Wright, and DOE Assistant Secretary of Nuclear Energy Ted Garrish.

U.S. representation was further bolstered by an industry delegation that included 65 participants from 32 companies, many of whom used the opportunity to report progress on their plans for the international expansion of their nuclear fleets. Meetings of that industry delegation were coordinated by the Nuclear Energy Institute.

Aside from the main conference, Piercy and I also attended the embedded meetings of the International Nuclear Society Council. INSC exists to facilitate knowledge-sharing and collaboration between 18 different member nuclear societies from around the world.

The INSC meetings within the General Conference brought together the presidents and senior members of those societies to give presentations and explore new opportunities. I made a presentation on the state of nuclear in North America, covering the latest developments and deployments in the U.S. and Canada.

This presentation emphasized the new nuclear lift in the U.S. that is being heavily supported by the Trump administration. I recapped the four executive orders issued by President Trump in May, the recent momentum at the DOE, and how these changes are capitalizing on a broader groundswell in both industry development and public support.

I also pointed out the success of our neighbor Canada in progressing on the first water-cooled small modular reactor in North America using BWRX-300 technology, which was supplied by an American firm and international partners—a perfect symbol of the value of global nuclear collaboration.

In all, I have now represented ANS at the state, national, and international levels, gaining useful insight into the work that needs to be done at each. From this vantage point, it’s clear to me that the path forward from the country to the globe is to, above all else, keep working together and supporting each other to bring about the next age of nuclear.

When small modular reactors and other advanced nuclear plants someday provide electricity, hydrogen, desalination, and district heating, the North Carolina Collaboratory will deserve some credit. Headquartered at the University of North Carolina–Chapel Hill, the collaboratory is a research funding agency established by the North Carolina General Assembly in 2016 to partner with academic institutions and government agencies. Its goal is to help transform research into practical applications for the benefit of North Carolina’s state and local economies. To that end, it engages in research projects related to advanced nuclear energy, among other initiatives.

RP3C Community of Practice’s fifth anniversary

In February, the Community of Practice (CoP) webinar series, hosted by the American Nuclear Society Standards Board’s Risk-informed, Performance-based Principles and Policies Committee (RP3C), celebrated its fifth anniversary. Like so many online events, these CoPs brought people together at a time when interacting with others became challenging in early 2020. Since the kickoff CoP, which highlighted the impact that systems engineering has on the design of NuScale’s small modular reactor, the last Friday of most months has featured a new speaker leading a discussion on the use of risk-informed, performance-based (RIPB) thinking in the nuclear industry. Providing a venue to convene for people within ANS and those who found their way online by another route, CoPs are an opportunity for the community to receive answers to their burning questions about the subject at hand. With 50–100 active online participants most months, the conversation is always lively, and knowledge flows freely.

SMR simulator development is focus of North Carolina grant

Informal survey asks when the next U.S. nuclear plant will come on line

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.

2024: The State of Advanced Reactors

January 19, 2024, 3:07PMNuclear NewsMatt Wald

Designs for high-tech products, and the start-ups that offer them, will always outnumber the commercial successes. Ditto: many more power plants are proposed than actually get built, no matter what the technology.

This is an axiom of free-market economies, but in early November 2023 it became painfully obvious in the advanced reactor field. NuScale Power, the only advanced reactor that has made it through the licensing gauntlet, acknowledged that the consortium of utilities that was its intended launch customer had failed to put together a feasible package.

How was the BWRX-300 designed to keep construction costs in check?

January 8, 2024, 3:00PMNuclear NewsDennis Henneke

Dennis Henneke

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.
