Advanced Decommissioning Partners, a joint venture of NorthStar Group Services and Orano USA, is set to complete major decommissioning activities at Crystal River-3 nuclear power plant in Florida this summer, according to the license termination plan (LTP) the company submitted to the Nuclear Regulatory Commission.

The American Nuclear Society recently opened two draft standards for public review. Previously, announcements of public review opportunities for ANS standards have been published exclusively in the American National Standards Institute’s weekly ANSI Standards Action publication.

Eden Radioisotopes has filed a construction permit application with the Nuclear Regulatory Commission for a facility to produce medical radioisotopes, primarily molybdenum-99 and lutetium-177.

The United States has lacked a reliable domestic source of Mo-99 for diagnostic imaging for decades, and has invested in infrastructure in South Africa, the Netherlands, and Belgium to assist facilities in producing the isotope using HALEU targets. These reactors are old, and there have been disruptions to the supply chain due to unplanned outages for repairs. With a 66-hour half-life, Mo-99 cannot be stockpiled.

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.

Today, commercial microreactors are common in the marketplace of nuclear ideas. Dozens of companies are vying for their designs to reach scaled deployment to meet surging energy demand.

However, the term “microreactor” didn’t appear in Nuclear News until 2019, when the Department of Defense popularized it (in a nuclear context) in the early days of what would become Project Pele. Even before then, however, all the way back in 2005, Toshiba was developing the 4S (Super-Safe, Small, and Simple), a 30-MWt, pool-type reactor designed for remote locations with small grids. Once sealed and delivered, the reactor would run for 30 years with no refueling. If the word “microreactor” had been in use then, the 4S would certainly have been categorized as such.

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.

The Nuclear Regulatory Commission has released a new licensing framework for microreactors and similar reactor designs that may provide a more suitable pathway for applicants with simpler technologies.

The proposed rule—known as Part 57—is the latest to come out of the NRC’s rules review and overhaul stemming from the ADVANCE Act and 2025 nuclear-related executive orders. It is also the latest framework developed for advanced reactor designs shifting away from light water reactor technology, such as the Part 53 rule finalized in March.

Orano USA announced on April 22 that it has signed a memorandum of understanding with North America’s Building Trades Unions (NABTU) outlining their cooperative relationship to support the construction of Project Ike, Orano’s planned $5 billion centrifuge uranium enrichment facility in Oak Ridge, Tenn.

All five commissioners of the Nuclear Regulatory Commission provided insight into the agency’s priorities, activities, and its proposed $892.3 million budget for fiscal year 2027 when they testified before the U.S. House Committee on Energy & Commerce’s Energy subcommittee on Wednesday.

The French Authority for Nuclear Safety and Radiation Protection (ASNR) has published a decision on how it will be regulating ITER, opting to approve the organization’s request to exclude its vacuum vessel from French and European pressure equipment rules.

The Nuclear Regulatory Commission is moving forward with its plans to reorganize around three core business lines: new reactors, operating reactors, and nuclear materials and waste. In order to do that, the agency will establish two new offices: the Office of Advanced Reactors (OAR) and the Office of the Chief Nuclear Reactor Inspector (CNRI).

The American Nuclear Society’s 2026 Annual Conference is coming up fast. From May 31 to June 3, leaders from across the nuclear industry will gather in Denver, Colo., to discuss the state of the industry and emerging opportunities.

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.

Sen. Mike Lee (R., Utah), chair of the Senate Committee on Energy and Natural Resources (ENR), has introduced a bill that would grant the Department of Energy greater authority over new nuclear projects under the federal agency’s oversight.

New Jersey has become the latest state to lift a moratorium on the construction of new nuclear power plants, with Gov. Mikie Sherrill signing new legislation Wednesday with the state’s two nuclear power plants serving as the backdrop.

The legislation, S. 3870/A. 4528, allows the commissioner of the state’s Department of Environmental Protection to approve permits for the construction and operation of new nuclear facilities “based on safe, [Nuclear Regulatory Commission]–compliant waste storage.” Prior to this bill, New Jersey law practically banned such construction, because the state’s Coastal Area Facility Review Act required an approved method from the NRC for radioactive waste disposal that was outdated and could not be met.

The security drills held at commercial nuclear power plants as part of the Force-on-Force (FOF) inspection program will no longer be led by the Nuclear Regulatory Commission.

The commissioners on Friday approved an overhaul of the security program, including phasing out NRC-led drills by 2028. Following the phaseout, drills will be led by the licensee, with the NRC observing.

The Nuclear Regulatory Commission has sunset its aircraft impact assessment rule for 2027, as NRC staff have addressed several of the public comments considered “significant and adverse” that prompted the agency this past winter to temporarily delay the sunsetting move.

The final rule, which was published in the Federal Register on Wednesday, addressed some of the more contentious concerns raised by the public. It sets a conditional sunset date of April 8, 2027, “unless the NRC determines that the cessation deadline should be extended to a date not more than 5 years in the future after offering the public an opportunity to provide input on the costs and benefits of this section and considering that input.”

The White House is requesting $1.5 billion for the Department of Energy’s Office of Nuclear Energy in the fiscal year 2027 budget proposal, about 9 percent less than the previous year.

The request from the Trump administration is one of several associated with nuclear energy in the proposal, which was released Friday. Congress still must review and vote on the budget.
