U.S. nuclear capacity additions are falling short of ambitious expectations set (and then reset) in recent years. Despite construction permits submitted or approved at this writing, new commercial, utility-scale nuclear generation is still a few years away from operation.
New Jersey’s two nuclear power plants, Hope Creek and Salem, may be joined by other nuclear facilities after lawmakers lifted the state’s de facto moratorium on new nuclear construction.
Gov. Mikie Sherrill said state officials are eyeing sites for potential nuclear facilities. Executives at PSEG Nuclear—the operators of Hope Creek and Salem—welcome the news of the growing momentum for nuclear power in the state but cautioned it will take more than lifting a moratorium to make this feasible.
The Nuclear Regulatory Commission has accepted Radiant Industries’ 10 CFR Part 70 license application for its R-50 microreactor production facility in Oak Ridge, Tenn., and will launch an expedited review that it is aiming to complete within eight months.
According to NRC documents, the agency expects to complete its review of the license application by December 18, 2026. The timeline is described as “accelerated” in the NRC announcement—about 55 percent faster than the typical 18 months for Part 70 application reviews.
The Nuclear Company, a nuclear power project development firm, is partnering with global investment firm Brookfield to form a new company specializing in the execution of projects involving Westinghouse nuclear reactors.
X-energy recently announced that it has begun collaborating with Louisville Gas and Electric Company and Kentucky Utilities to deploy X-energy’s Xe-100 reactor in Kentucky. The news comes soon after X-energy went public on the Nasdaq and represents the latest in a string of growing investments Kentucky has made in nuclear development over the last two years.
The Nuclear Regulatory Commission has approved subsequent license renewals for St. Lucie Units 1 and 2, extending the operating licenses for the pressurized water reactors by another 20 years.
Tuesday’s approval means that the 1,062-MWe Unit 1 and 1,074-MWe Unit 2 can now operate until March 1, 2056, and April 6, 2063, respectively. Unit 1 commenced operations in 1976 and Unit 2 in 1983. With the original 40-year operating licenses and first 20-year renewals, these second 20-year renewals bring the reactors’ lifespan to 80 years.
The Nuclear Regulatory Commission has renewed the Robinson nuclear power plant’s operating license in record time, the agency announced last week.
The subsequent license renewal process for the Hartsville, S.C., facility was completed within 12 months, according to the NRC. The process has typically taken 18 months. This was the first license renewal review conducted under the directive of Executive Order 14300 to streamline processes like renewing operating licenses.
A newly signed contract between U.K.-based Rolls-Royce SMR and the ČEZ Group in the Czech Republic will allow for design work to begin on the planned small modular reactors at the Temelín nuclear power plant site in the Czech Republic. The companies, which hope to deploy as much as 3 gigawatts of new nuclear capacity in the country, signed an early works contract that will see them begin preparing for consents, permitting, and licensing and continuing preliminary infrastructure activities as they develop a site application for the SMRs.
The Department of the Air Force has selected three companies to be potential developers and operators of microreactors at Air Force installations as part of the Advanced Nuclear Power for Installations (ANPI) program: Radiant Industries, Antares Nuclear, and Westinghouse Government Services.
The communities in and around Duane Arnold had a chance on Tuesday evening to hear from Nuclear Regulatory Commission officials on the progress to restart Iowa’s only nuclear power plant in early 2029.
Licensing, inspections and assessments, the noticing process, and the role of the restart panel were among the topics discussed at the public meeting, which was held in Cedar Rapids, Ia., with an option for virtual attendance.

The Department of the Air Force (DAF) and the Defense Innovation Unit within the Department of Defense have selected Buckley Space Force Base in Colorado and Malmstrom Air Force Base in Montana to potentially site microreactors.
Wednesday’s announcement moves forward the plans of the Advanced Nuclear Power for Installations (ANPI) program, which was launched in 2024 with the objective of deploying “advanced, contractor-owned and operated” microreactors from commercial reactor companies on bases.
Yesterday, the Nuclear Regulatory Commission announced that it has received an application from Westinghouse to renew and update the design certification (DC) for its AP1000 reactor. This application seeks to formally incorporate the lessons learned from the construction of Vogtle-3 and -4 into the design control document (DCD) of the AP1000.
This long-expected submittal builds on previous plans at both the NRC and Westinghouse for the future of gigawatt-scale light water reactor deployments in the United States.
The Nuclear Regulatory Commission has approved Pacific Gas & Electric’s application to extend the operating licenses for Diablo Canyon nuclear power plant’s two pressurized water reactors by another 20 years.
Thursday’s approval means Diablo Canyon-1 and -2 can now operate until November 2, 2044, and August 26, 2045, respectively, if California lawmakers agree. A 2022 state law requires the California Legislature to approve any extension of operations at Diablo Canyon that goes beyond 2030.
When the former Three Mile Island-1 restarts in 2027 as the Crane Clean Energy Center, it will not face a delay of several years before it can be reconnected to the grid, Constellation CEO Joseph Dominguez said this week.
Among the items that emerged on Constellation and the Crane restart in Middletown, Pa., during last week’s CERAWeek energy conference was a Reuters report on an analysis from electric grid provider PJM suggesting the plant may not be connected to the grid until 2031.
Polskie Elektrownie Jądrowe, Poland’s state-owned utility, has formally submitted an application for a construction license to build a nuclear power plant at the Lubiatowo-Kopalino site in Pomerania. The country’s first nuclear power plant will consist of three Westinghouse AP1000 units with a total installed capacity of 3,750 MWe. The construction and engineering contractor for the project is a U.S.-based consortium of Westinghouse and Bechtel.

The restart of Palisades nuclear power plant in Covert, Mich., has hit a milestone with the passivation of its primary system, plant owner Holtec International announced Monday, even as a firm restart date has yet to be announced.
Passivation is a chemical process that improves corrosion resistance by making plant materials less reactive. During the process, the reactor’s primary system was brought to normal operating temperature and pressure. Holtec called this passivation phase an “essential step” in maintaining the long-term reliability of equipment.
The Nuclear Regulatory Commission has approved a significant overhaul of its Reactor Oversight Process (ROP) baseline inspection program that stresses a leaner, more risk-focused inspection process.
This adoption comes just over a month after NRC officials published their findings on the proposed ROP changes. The changes would reduce the number of hours spent annually on direct inspections at U.S. nuclear power plants by 38 percent.
The U.S. Air Force wants to hear from companies that could be interested in deploying small nuclear reactors at its bases.
The request for information posted Wednesday intends to assist the federal government in identifying potential developers and “understanding the company’s capability to design, license, fuel, construct, and deploy Small, Micro, or Modular Reactor (SMR) technologies in compliance with applicable regulatory, safety, environmental, and security requirements.”
Microsoft and Nvidia have formed an “AI for nuclear” partnership intended to streamline the permitting, design, and operations of nuclear power plant facilities, and highlighted the collaboration at CERAWeek 2026 in Houston earlier this week.
