Urenco USA has initiated production of enriched uranium in its newest gas centrifuge enrichment cascade—the first in a planned expansion of its Eunice, N.M., facility announced in July 2023. When the expansion is complete, early in 2027, the site will have increased its capacity by about 15 percent, adding about 700,000 separative work units (SWU) per year, the company said May 19.

An initiative to educate government, regulatory, and industry representatives around the world about small modular reactors has been launched by the International Atomic Energy Agency, with the first such “SMR School” workshop, which was hosted by the government of Kenya in the capital city of Nairobi from on May 5–9.

As state legislatures nationwide near the end of their spring sessions, nuclear advocates hope to spur momentum on Texas legislation that would provide taxpayer-funded grants to developers of new nuclear technology in the state.

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.

Santee Cooper is satisfied with the response generated by its initial request for proposals to buy what remains of the Summer-2 and -3 nuclear power plant project in South Carolina. The RFP was issued in January and the application window closed May 5.

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.

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.

The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

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.

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.

Nuclear waste disposal technology company Deep Isolation announced it has successfully completed Project PUCK, a government-funded initiative to demonstrate the feasibility and potential commercial readiness of its Universal Canister System (UCS) to manage TRISO spent nuclear fuel.

Canada’s Nuclear Waste Management Organization has selected five companies it is to work with to design and plan the organization’s proposed deep geologic repository for spent nuclear fuel. As the owner of the project, the NWMO will be working with WSP Canada, Peter Kiewit Sons (Kiewit), Hatch Ltd., Thyssen Mining Construction of Canada, and Kinectrics.

The Nuclear Regulatory Commission has accepted Dow’s construction permit application to build an X-energy small modular reactor in Seadrift, Texas.

Applications are now open for the American Nuclear Society’s newly redesigned mentoring program. Mentor Match is a unique opportunity available only to ANS members that offers year-round mentorship and networking opportunities to Society members at any point in their education.

The deadline to apply for membership in the inaugural summer cohort, which will take place July 1–August 31, is June 20. The application form can be found here.

Utah-based EnergySolutions announced that it is working with Milwaukee-based utilities company WEC Energy Group to explore new nuclear generation in Wisconsin and will begin efforts to pursue an early site permit from the Nuclear Regulatory Commission for the closed Kewaunee nuclear power plant in Wisconsin.

Recent testing of a monitoring well in Minnesota near the Mississippi River detected tritium levels just below the safety standards set by the Environmental Protection Agency, Xcel Energy reported this week.

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.”

Spirits were high last month when a ribbon cutting was held at the University of Missouri for a $20 million, three-story, 47,000-square-foot addition, dubbed MURR West, to the MURR research reactor facilities.
