Dominion Energy Virginia is seeking a 20-year renewal of the early site permit (ESP) the Nuclear Regulatory Commission issued for its North Anna nuclear power plant site in Virginia. North Anna’s current ESP is set to expire on November 27, 2027.

On July 14, Dominion submitted the ESP renewal request for North Anna; the site in question is adjacent to Unit 1 and Unit 2 of the Louisa County, Va., facility. The NRC acknowledged receiving the application on July 28 and will now review the application before docketing it in the Federal Register and commencing with the review process.

Efforts by NextEra Energy to restart the Duane Arnold nuclear power plant as early as 2029 continue to move forward with the Nuclear Regulatory Commission's preliminary environmental assessment and determination that the restart would have no significant environmental impacts.

On Thursday, the NRC posted a draft environmental assessment and a finding of no significant impact for the Palo, Iowa, facility; the Federal Register notice was published on Monday. The Department of Energy’s Office of Energy Dominance Financing is a cooperating agency on the draft EA, as the DOE is considering providing financial assistance to the restart project.

The Nuclear Regulatory Commission held its latest public meeting in central Pennsylvania on Tuesday to provide an update the progress being made to restart the Crane nuclear power plant (formerly Three Mile Island-1) as early as 2027.

The meeting focused on emergency preparedness, with officials from both the NRC and the Federal Emergency Management Agency sharing how the agencies plan their on-site and off-site responses to potential emergencies.

Changes that Nuclear Regulatory Commission officials have labeled as significant could be coming to the agency’s environmental review regulations if its proposed rule on National Environmental Policy Act (NEPA) procedures moves forward.

With notable changes potentially incoming—such as no longer requiring draft environmental impact statements and the addition of new categorical exclusions—NRC staff shared additional details on these and other proposals during a July 23 meeting on the NEPA proposed rule.

Within the past month, the Nuclear Regulatory Commission has signed memorandums of understanding to increase its cooperation with two U.S. maritime organizations. In late June, the NRC signed an MOU with the U.S. Coast Guard to strengthen coordination on civilian maritime nuclear projects, including floating nuclear power plants and civilian nuclear propulsion. On July 21, the NRC signed an MOU with the newly formed Marine Minerals Administration (MMA) to improve cooperation regarding potential future nuclear projects on the Outer Continental Shelf.

On July 21, TerraPower announced that it had been accepted into the Institute of Nuclear Power Operations. INPO and TerraPower alike celebrated the development as the first time an advanced nuclear company has joined the institute’s ranks, representing an important step forward in safety and industry coordination among newcomers to the nuclear industry.

About three million packages containing radioactive material are transported in the United States every year, and multiple federal agencies work together to ensure the shipments are safe. While the Nuclear Regulatory Commission addresses the design and use of packaging, for example, the Department of Transportation oversees shipments.

Amidst growing prominence of microreactors and other nuclear technologies, the NRC has issued a proposed rule to address how to safely transport new nuclear reactors and their associated radioactive material.

The public had a rare opportunity Tuesday morning when the Nuclear Regulatory Commission gathered leaders from the Department of Energy, the Canadian Nuclear Safety Commission, TerraPower, Radiant, Westinghouse, and X-energy to share updates on their respective high-profile new nuclear projects and initiatives.

During the meeting, titled “Advanced Reactor Landscape: Current Status and Moving Forward,” federal and industry officials presented on their respective endeavors, providing new updates, refreshers on previously announced information, and takeaways from their experiences.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) is currently seeking qualified candidates to fill an open committee member position. Applications for the position will be accepted until July 30. The ACRS is the world’s oldest organization devoted to reactor safety, and the group reports directly to the NRC’s commissioners in order to provide independent technical reviews of and advice on a wide variety of nuclear topics.

The Nuclear Regulatory Commission has accepted Constellation’s subsequent license renewal application to extend operations at the Ginna nuclear power plant by another 20 years.

If approved, the Ontario, N.Y., facility’s operating license would be extended through September 18, 2049. The plant was first issued a 40-year license in 1969, followed by a 20-year renewal in 2004 that extended the license into 2029.

As human factors specialists working at the intersection of human performance and nuclear operations, we are witnessing one of the nuclear sector’s most significant transitions in decades. The emergence of small modular reactors, microreactors, and other advanced designs is reshaping the industry’s landscape. Digital instrumentation and controls, passive safety systems, and increased automation are creating opportunities for greater safety margins and more flexible operation. These same features also fundamentally redefine what it means to “operate” a nuclear plant. Interactions among human roles, automation, and passive systems shape how people maintain awareness, exercise judgment, and intervene when necessary. These developments affect both operational realities and the regulatory foundations on which nuclear safety is built.

In the span of just over a week in late June and early July, the Nuclear Regulatory Commission published three proposed rules on modernizing security requirements, low-level radioactive waste disposal requirements, and fuel cycle and materials licensing.

This week, NRC staff led separate virtual public information meetings on each of the proposed rules, providing details to the public on what each one would change.

The U.S. House Energy and Commerce Committee’s Subcommittee on Energy introduced six nuclear permitting reform bills back in June. The mostly bipartisan bills returned to the subcommittee on Tuesday for markups—and with strong backing from both sides of the aisle.

Despite some lingering concerns in areas like federal transparency, the role of the Advisory Committee on Reactor Safeguards (ACRS), and staff attrition in the Nuclear Regulatory Commission, the subcommittee advanced all six pieces of legislation to the full committee with bipartisan support.

Westinghouse has cleared a hurdle in its quest to renew and update the standard design certification (DC) for its AP1000 reactor with the Nuclear Regulatory Commission’s approval of an exemption from scheduling requirements that limit when an applicant can apply for a DC renewal.

On July 1, the Nuclear Regulatory Commission proposed removing the “as low as reasonably achievable” (ALARA) principle from its radiation protection regulations and replacing it with a graded approach. The agency also proposed increases to effluent dose limits and adjusting how it handles allowances for exceeding dose limits.

The Nuclear Regulatory Commission has upheld and finalized a “white” safety finding at V.C. Summer power plant in Jenkinsville, S.C., over the plant’s failure to properly preplan and perform maintenance on its turbine-driven emergency feedwater pump (TDEFW) governor valve linkage. The 966-MWe three-loop Westinghouse pressurized water reactor at Summer started commercial operation in 1982.

Make no mistake about it: the Nuclear Regulatory Commission’s proposed rulemaking on reactor licensing, safety oversight, and siting practices is expansive. When it was unveiled on July 1, NRC officials called it the “most comprehensive modernization of reactor licensing in decades,” one that could save the NRC and the industry as much as $1.86 billion.

“NRC’s regulations have not kept pace with new technologies and our energy needs,” NRC Chairman Ho Nieh said in an announcement. “This proposed rule strips out rigid frameworks and unnecessary conservatism to accelerate the safe deployment of new reactors and expand existing capacity across America.”

The American Nuclear Society recently opened a draft standard for public review.

ANS-8.22-202x, Nuclear Criticality Safety Based on Limiting and Controlling Moderators, is a revision of ANS-8.22-1997 and provides criteria for limiting and controlling moderators in operations with fissile materials.

The Nuclear Regulatory Commission is proposing changes to its environmental review regulations under the National Environmental Policy Act (NEPA) that agency officials call the most significant in decades.

The proposed rule—published in the Federal Register on Tuesday—streamlines 10 CFR Part 51 and calls for no longer requiring draft environmental impact statements (EIS), adding new categorical exclusions that exempt licensing actions from NEPA review, and reducing the regulatory burden in its environmental reviews, among other things. The NRC will accept public comments on the proposed rulemaking until August 21, with plans to hold a public hearing during the comment period.

The ongoing work to restart Holtec’s Palisades nuclear power plant, which last operated in 2022, has transitioned out of large-scale projects and into smaller activities, plant owner and operator Holtec International announced last week. However, no firm start date for the Covert, Mich., facility has been announced.
