The Nuclear Regulatory Commission is gearing up to tackle an influx of licensing requests and oversight of advanced nuclear reactor technology, especially small modular reactors.

The U.S. Supreme Court heard oral arguments on Wednesday in the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ consolidated interim storage facility in Andrews County, Texas. Both the NRC and ISP petitioned the Supreme Court to review a decision by the 5th Circuit Court of Appeals that invalidated the NRC-granted license for the facility. Those two cases were consolidated into one, NRC v. Texas, which was heard by the court.

Aiming to deploy the nation's first small modular reactor, TerraPower has announced contracts for the final long-lead items needed for its Natrium unit, currently under construction in Wyoming.

Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

The Nuclear Regulatory Commission has published its 2024–2025 Information Digest, NUREG-1350, Vol. 35, which describes the agency’s responsibilities and activities and provides general information regarding nuclear-related topics.

According to the NRC, the digest is intended to be a quick reference with important facts about the NRC and the industry it regulates presented publicly in an “easy-to-understand format” with visual aids.

The NRC published the digest annually from 1989 until 2023, when the agency switched to a two-year publication cycle. The next digest containing updated data will be published in February 2027.

Leaders from Holtec International and Hyundai Engineering & Construction gathered at the Palisades site in western Michigan today to announce an “expanded cooperation agreement” to build a 10-GW fleet of Holtec-designed SMR-300s in North America. That fleet’s first builds would be at Palisades, where Holtec is now focused on restarting the site’s shuttered 777-MWe pressurized water reactor by the end of this year. Under the “Mission 2030” plan launched today, Holtec would then build a pair of SMR-300 PWRs at the Palisades site—targeting operation in 2030.

The Nuclear Regulatory Commission is looking for feedback on its proposed rule for fees for fiscal year 2025. The proposal was published in the February 19 Federal Register. The federal government's fiscal year is the 12-month period from October 1 to September 30.

The proposed rule includes instructions on how to submit written comments to the NRC. Comments will be accepted through March 21, 2025.

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year U.S. dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

The Hill recently published an opinion piece by Cindy Folkers and Amanda Nichols entitled “They won’t tell you these truths about nuclear energy.” Sadly, after the first sentence, their so-called truth veers into a diatribe of antiscientific fearmongering and misrepresentations.

The top three utilities in Arizona are teaming up to explore opportunities to add nuclear generation facilities in the state.

Arizona Public Service (APS), Salt River Project (SRP), and Tucson Electric Power (TEP) announced in a February 5 news release that they are working together to assess possible sites, including retiring coal plants. The group is looking at possibilities for both small modular reactors—units generating 300 MW or less—and potential large reactor projects, which could generate nearly five times the power.

The Nuclear Regulatory Commission has published its final environmental impact statement for the proposed subsequent license renewal (SLR) for Oconee nuclear power plant's Units 1, 2, and 3.

The Nuclear Regulatory Commission is asking for public comments until March 3 on its environmental assessment (EA) and draft finding of no significant impact at Michigan’s Palisades nuclear power plant, where Holtec hopes to restart operations by the end of 2025.

South Carolina public utility Santee Cooper and its partner South Carolina Electric & Gas (SCE&G) called a halt to the Summer-2 and -3 AP1000 construction project in July 2017, citing costly delays and the bankruptcy of Westinghouse. The well-chronicled legal fallout included indictments and settlements, and ultimately left Santee Cooper with the ownership of nonnuclear assets at the construction site in Jenkinsville, S.C.

The Nuclear Regulatory Commission has a new mission statement to formalize the agency’s pledge to “be a part of the solution” in bringing new nuclear energy projects to life across the country.

A flurry of amicus briefs from states, politicians, and special interest groups were filed with the U.S. Supreme Court this week, urging the court to uphold a 5th Circuit Court of Appeals ruling that invalidated Interim Storage Partners' license for a consolidated interim storage facility for commercial spent nuclear fuel in Andrews County, Texas.

A Nuclear Regulatory Commission review board will hear oral arguments on February 12 on petitions concerning Holtec Palisades LLC.

Southern Nuclear was first when no one wanted to be.

The nuclear subsidiary of the century-old utility Southern Company, based in Atlanta, Ga., joined a pack of nuclear companies in the early 2000s—during what was then dubbed a “nuclear renaissance”—bullish on plans for new large nuclear facilities and adding thousands of new carbon-free megawatts to the grid.

In 2008, Southern Nuclear applied for a combined construction and operating license (COL), positioning the company to receive the first such license from the U.S. Nuclear Regulatory Commission in 2012. Also in 2008, Southern became the first U.S. company to sign an engineering, procurement, and construction contract for a Generation III+ reactor. Southern chose Westinghouse’s AP1000 pressurized water reactor, which was certified by the NRC in December 2011.

Fast forward a dozen years—which saw dozens of setbacks and hundreds of successes—and Southern Nuclear and its stakeholders celebrated the completion of Vogtle Units 3 and 4: the first new commercial nuclear power construction project completed in the U.S. in more than 30 years.

Progress continues for TerraPower’s Natrium plant, with the latest win coming in the form of a state permit for construction of nonnuclear portions of the advanced reactor.

The Department of Energy has announced a competitive funding opportunity of up to $13 million to help first movers defray the licensing costs of bringing advanced nuclear reactors to market.

Advanced nuclear reactor company Last Energy joined with two Republican state attorneys general in a lawsuit against the Nuclear Regulatory Commission, arguing that some microreactors should not require the commission’s approval.
