Three commercial power reactors across two Illinois nuclear power plants—Constellation’s Clinton and Dresden—have had their licenses renewed for 20 more years by the Nuclear Regulatory Commission.

WASHINGTON, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate’s confirmation of Douglas Weaver to serve as a commissioner of the U.S. Nuclear Regulatory Commission (NRC):

Pacific Gas & Electric has announced that the California Coastal Commission, the state agency in charge of protecting California’s roughly 840 miles of coastline, unanimously voted to approve the Act Consistency Certification and Coastal Development Permit for Diablo Canyon, a critical step in the utility’s work to extend the life of the nuclear power plant.

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.

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.

Nieh

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.”

The Nuclear Regulatory Commission announced that it has received the first portion of a construction permit application from Oklo subsidiary Atomic Alchemy that requests permission to build four nonpower reactors for a radioisotope production facility at Idaho National Laboratory. The submission is now available for public inspection on the NRC website.

Nieh

Earlier today, the U.S. Senate officially confirmed Ho Nieh in a 66–32 vote to serve as a commissioner on the U.S. Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029. All present Republicans, alongside 15 Democrats and one Independent, cast their votes in favor of Nieh, who was nominated by President Trump in July and fills the seat left vacant following the dismissal of former commissioner Christopher Hanson.

NRC details: The commission leading the NRC now comprises four members. Nieh joins Chair David Wright and commissioners Bradley Crowell and Matthew Marzano. One spot remains unfilled after the resignation of Annie Caputo in July. President Trump nominated Douglas Weaver earlier this month to fill Caputo’s seat.

WASHINGTON, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate’s confirmation of Ho Nieh to serve as a commissioner of the U.S. Nuclear Regulatory Commission (NRC):

Due to the days lost to the government shutdown, the Nuclear Regulatory Commission has extended the public comment period for a draft environmental impact statement for the TX-1 advanced nuclear fuel fabrication facility being built in Oak Ridge, Tenn.

Small modular reactor developer X-energy and its subsidiary TRISO-X announced yesterday the start of aboveground construction for its TX-1 advanced nuclear fuel fabrication facility in Oak Ridge, Tenn.  The first-in-the-nation facility will be the first of two Oak Ridge facilities built to manufacture the company’s TRISO fuel for use in its Xe-100 SMR.

The Nuclear Regulatory Commission could do more to improve its oversight of decommissioning trust funds, according to an assessment by the NRC’s Office of Inspector General. In particular, the assessment, which was conducted by Crowe LLP on behalf of the OIG, identified four areas related to developing policies and procedures, workflows, and other support that would enhance NRC oversight of the trust funds.

Hawthorne, Calif.–based reactor start-up Valar Atomics recently announced that it has raised $130 million in its Series A funding round, led by venture capital groups Snowpoint, Day One, and Dream.

The U.S. Supreme Court may once again scrutinize the Nuclear Regulatory Commission’s authority to license consolidated interim storage facilities for commercial spent nuclear fuel. The antinuclear group Beyond Nuclear has filed a petition with the court for a writ of certiorari review of an August 2024 appeals court decision rejecting the group’s lawsuit against the licensing of Holtec International’s New Mexico storage facility, the HI-STORE CISF.

Advanced reactor and fuel developer X-energy has officially begun confirmatory irradiation testing at Idaho National Laboratory on its TRISO-X fuel. The testing, which is taking place over the course of the next 13 months, will evaluate the fuel across a variety of operating scenarios and—if all goes according to plan—will be instrumental in qualifying it for commercial use.

At the American Nuclear Society’s Winter Conference & Expo, leaders of advanced reactor start-ups Radiant Industries, Oklo, and Valar Atomics praised the Department of Energy’s Reactor Pilot Program, in which the companies are participating. The program aims to get at least three reactors on line by July 4, 2026.

During speeches at the American Nuclear Society’s Winter Conference & Expo, happening this week in Washington, D.C., Energy Secretary Chris Wright and Nuclear Regulatory Commission Chair David Wright both promised that the Trump administration will speed up nuclear reviews so the U.S. can maintain leadership in nuclear energy.

The DOE’s Wright took a stab at the NRC’s traditionally slow bureaucratic processes in approving primarily large light water reactors in the past, saying that the agency needs to speed up to meet the greater demand for new small modular reactors.

The Trump White House has nominated seasoned nuclear regulatory expert Douglas Weaver for a commissioner seat on the Nuclear Regulatory Commission. If confirmed, Weaver would fill the seat vacated by NRC commissioner Annie Caputo, who resigned in July.

Weaver’s nomination was sent earlier today to the Senate Environment and Public Works Committee. If confirmed, he would finish the remainder of Caputo’s term, which expires June 30, 2026.

The Nuclear Regulatory Commission and the Department of Energy have updated a 2019 memorandum of understanding to coordinate on the review of advanced nuclear reactors and advanced reactor fuel technologies.

The Nuclear Regulatory Commission has announced it is canceling an upcoming advanced reactor stakeholder meeting, originally scheduled for November 19, due to the government shutdown and the limitations on staffing at the agency.
