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.

GAO: Better data could save DOE-EM millions

May 7, 2026, 4:00PMNuclear News

A recent Government Accountability Office report found that the Department of Energy's Office of Environmental Management faces significant aging infrastructure, data accuracy issues, and funding challenges in managing nuclear waste cleanup facilities.

As of June 2025, DOE-EM faced more than $1.5 billion in reported repair needs across about 4,300 operating facilities at the 15 cleanup sites the office oversees, according to the report. In addition, DOE-EM’s budget request included over $950 million in maintenance spending in fiscal year 2026, an 80 percent increase since FY 2020.

Three companies have come together to form the U.K. Infinity Fusion Consortium with the objective of developing the first private sector–led fusion power plant in the United Kingdom using existing “commercially credible” technologies.

The consortium is expected to benefit from the combination of the three partners’ expertise. Tennessee-based fusion start-up Type One Energy brings its 400-MWe Infinity Two stellarator fusion power plant design. British fusion technology company Tokamak Energy has its HTS magnet technology and manufacturing background. Texas-based consulting firm AECOM has international engineering and infrastructure capabilities.

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 microreactordidn’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.

Blue Energy, GE Vernova plan “gas-plus-nuclear” power plant in Texas

May 5, 2026, 4:39PMNuclear News

GE Vernova has formed a strategic collaboration with nuclear project financing and manufacturing firm Blue Energy to “advance the world’s first gas-plus-nuclear power plant.” The companies say that they intend to design and develop a power plant using GE Vernova Hitachi Nuclear Energy BWRX-300 small modular reactors and GE Vernova gas turbines to meet electricity demands related to AI and advanced manufacturing. Subject to a final investment decision in 2027, the first plant is to be located at a Blue Energy site in Texas and will power a nearby data center campus.
