AI and productivity growth

This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.

Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.

or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

The National Atomic Testing Museum, better known as the Atomic Museum, is celebrating its 20th anniversary this year. Located in Las Vegas, Nev., the museum was established in 2005 to preserve the legacy of the Nevada Test Site, now called the Nevada National Security Sites.

NRC discontinues spent fuel pool rulemaking

The Nuclear Regulatory Commission is discontinuing its rulemaking activity, “Long-Term and Unattended Water Makeup of Spent Fuel Pools,” and denying a petition for rulemaking. The new rule, as requested by the petitioner, would have required nuclear power plant licensees to ensure that their spent nuclear fuel pools are capable of cooling and maintaining water levels during extended power outages.

In commemoration of National Maritime Day, there will be an open house on the NS Savannah this Sunday, May 18, in Baltimore, Md. The world’s first nuclear-powered merchant ship, Savannah was built through a joint program between the Atomic Energy Commission and the Maritime Administration (MARAD) as part of President Eisenhower’s Atoms for Peace program.

Here’s a look at some recent announcements from the Nuclear Regulatory Commission.

Summer SLR: The NRC this month published its final environmental impact statement for Summer Unit 1’s subsequent license renewal application. Dubbed a supplemental EIS, the report is an important step in determining if Dominion Energy can continue operating its 966-MWe Westinghouse pressurized water reactor unit for an additional 20 years beyond August 6, 2042, the current end of its license.

ANS holds Educator Training webinar on nuclear waste

Fri, May 16, 2025, 12:00PMANS News

A recent American Nuclear Society webinar tackled misconceptions about nuclear waste. Christopher Perfetti, an associate professor of nuclear engineering at the University of New Mexico, presented “The How, Why, and Where of Nuclear Waste,” the latest online event in ANS’s Educator Training series.

Moderated by ANS past president Eric Loewen (2011–12), this presentation was built to be an accessible and informative Nuclear Waste 101 offering as part of the Society’s broader effort to develop a program specifically tailored to educating K-12 teachers.

The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.

Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

NC State releases feasibility study for new research and test reactor

Wed, May 14, 2025, 12:01PMNuclear News

North Carolina State University has completed a feasibility study for its planned advanced research and test reactor. The $3 million study, which was undertaken by the university at the direction of the North Carolina General Assembly, is described in the full report and includes recommendations and projected costs and timelines.

Reactor type: NC State prefers the new reactor to be of “a multipurpose advanced sodium-cooled mixed/coupled spectrum design,” according to the report. Such a design would make the reactor “the only sodium-cooled fast research and test reactor in the country.”
