The NRC Prepares for Advanced Reactor Designers to Come Knocking

Jennifer Uhle
Director, Office of New Reactors

Today’s conversations about powering civilization in the future often propose carbon-free energy sources. In addition to solar and wind, these conversations sometimes touch on advanced nuclear reactor designs. Designers have yet to submit any of these designs for NRC review, but we expect applications in the future and we’re preparing for them.

These technology approaches range from evolutions on proven technology (such as high-temperature gas reactors) to innovative concepts that would re-use the “waste” nuclear fuel from today’s reactors.

I recently took part in one of these discussions at the Third Way group’s first Advanced Nuclear Summit and Showcase at the Newseum in Washington, D.C. The NRC contributed to the summit due to its focus – what can agencies and legislators in Washington do to support development of advanced nuclear designs? The NRC’s only role is ensuring these designs meet stringent safety standards.

My portion of the discussion involved the NRC’s review of reactor designs to meet our mission of protecting public health and safety. As I told the audience, we carry out that work as efficiently as possible so that the NRC avoids becoming a roadblock to deployment of appropriate technologies.

The NRC’s looking ahead to potential applications for reactors cooled by something besides water. Our limited advanced reactor budget includes work to stay up to date on this “non-light water reactor (LWR)” technology development. Vendors are considering many non-LWR technologies for future licensing work. We’re taking a technology-neutral approach to stay properly positioned to efficiently review whatever vendors submit.

The summit also attracted non-LWR designers, venture capitalists, the Department of Energy, national laboratories, industry groups, universities, media, and think tanks, such as the Clean Air Task Force. Members of Congress attended the summit to discuss proposed legislation related to nuclear power.

Advanced reactor designers told the audience they’re targeting deployment in the 2020s to the 2030s, depending on where their designs are in development. The NRC’s preparation for potential advanced reactor applications includes our ongoing partnership with the Department of Energy. DOE’s support for research and design activities will help vendors gather the information they need for their design applications.

The next milestone in that partnership will be our second advanced non-light water reactor workshop, currently scheduled for June. This workshop will present DOE’s strategies to support the development, and NRC’s plans for efficient licensing of advanced reactors.
