The operating licenses for the three boiling water reactors at Browns Ferry nuclear power plant, in Athens, Ala., have each been renewed by the Nuclear Regulatory Commission for an additional 20 years. The reactors, operated by the Tennessee Valley Authority, are now licensed to operate until December 2053 for Unit 1, June 2054 for Unit 2, and July 2056 for Unit 3.

Standard Nuclear executes OTA with DOE

December 12, 2025, 12:01PMNuclear News

Reactor-agnostic TRISO fuel producer Standard Nuclear recently announced that it has executed an other transaction agreement (OTA) with the Department of Energy. As one of the five companies involved in the DOE’s Fuel Line Pilot Program, its entrance into this deal marks a milestone in the public-private effort to bring advanced fuel production on line in support of the DOE’s concurrently running Reactor Pilot Program.

NRC proposes rule changes in response to EO

December 11, 2025, 3:00PMNuclear News

In April, President Donald Trump signed Executive Order 14270, “Zero-Based Regulatory Budgeting to Unleash American Energy,” which calls for the Nuclear Regulatory Commission (along with the Department of Energy, the Federal Energy Regulatory Commission, and the Environmental Protection Agency) to issue a “sunset rule” to effectively nullify certain regulations in no more than five years.

The Nuclear Regulatory Commission is now back up to four commissioners. Following a 66–32 confirmation vote in the U.S. Senate last month, Ho Nieh was officially sworn in last week.

He fills the seat left vacant following the dismissal of Christopher Hanson and is set to serve through the remainder of a term that will expire June 30, 2029.

Quotable: “I am grateful for the opportunity to return to the NRC to work alongside such a competent and dedicated workforce," said Nieh, in the NRC’s press release announcing his being sworn in. "This agency shaped my career and my commitment to nuclear safety. It is an incredible honor to have been appointed by President Trump to serve on the Commission, and I look forward to serving alongside Chairman Wright, Commissioner Crowell, and Commissioner Marzano. I am energized by the opportunities the NRC has to enable the safe use of nuclear technologies for America during this pivotal period in its history.”

U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.

Report: Funding growth for private fusion companies

December 5, 2025, 12:02PMNuclear News

A new report from the F4E Fusion Observatory highlights the robust growth of investments in private companies that are developing fusion energy technologies. The report, Global Investment in the Private Fusion Sector, is an updated release of a previous F4E Fusion Observatory report, published “in response to the unprecedented acceleration of investments in fusion companies since June 2025, which are consolidating fusion as a fast-growing emerging market.”

Global funding: According to the report, the cumulative global funding in private fusion companies between June and September 2025 increased from €9.9 billion to €13 billion (about $11.6 billion to $15.17 billion). Funding for the private fusion sector in September was more than eight times greater than in 2020. The report also identifies 77 companies that are in the “fusion private ecosystem.”
