X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Judge Dismisses Suit Against Cheney-Led Panel

LCG, Dec. 9, 2002--A lawsuit brought by David M. Walker, head of the General Accounting Office (GAO), against Vice-President Dick Cheney concerning communications which helped shape the Bush Administration's energy policy, was dismissed today by Judge John D. Bates in Federal District Court.

In bringing the lawsuit, Judge Bates said Walker did so without significant backing from Congress, which appointed him to lead the GAO, Congress' investigative arm and an agency widely perceived to be free from partisan biases. Bates found that such a suit would have to meet "especially rigorous" standards in order to be considered, since it would bring the judicial branch into a matter involving the constitutional separation of power between the executive and legislative branches.

Walker, who served under Republican presidents Reagan and the elder President Bush, said in February, "The GAO is not asking for information regarding conversations between administration officials, but between the White House and outside parties." His lawsuit arose after Cheney refused in 2001 to turn over to the GAO records of those present at meetings Cheney and his staff held with business leaders and others policy advisors. He said objections by Cheney that Walker was asking for "recommendations, deliberations, minutes or notes" were "misrepresentations."

The case may be appealed, possibly to the Supreme Court, and marks the first time that the 81-year-old agency has brought a lawsuit against the executive branch.
