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.

PG&E Told to Defend Legality of Reorg Plan

LCG, Dec. 5, 2001--U.S. Bankruptcy Judge Dennis Montali yesterday told Pacific Gas & Electric Co. that it would have to defend the legality of its reorganization plan at a January 25 hearing on the co-called "preemption issue" raised by state regulators.

PG&E's plan to emerge from its Chapter 11 bankruptcy relies in large part on Montali's willingness to preempt state regulations that limit a utility's right to sell power plants and other assets. While the company has not suggested that it wants to sell its remaining power plants, it does want to transfer them into a non-regulated subsidiary of its parent holding company PG&E Corp.

The California Public Utilities Commission had asked for a separate trial on the issue, but Montali rejected the request. Even so, Gary Cohen, general counsel for the CPUC, said "Overall, I'm pleased with what happened today."

PG&E was also pleased. Oscar Cantu, a lawyer for the utility, said the judge's ruling had put the monkey on the CPU's back. "It's their burden to show there is no set of circumstances" under which the reorganization plan could be found legal by the court, he said.

There are a number of laws with which the PG&E plan may be in conflict, most notably legislation passed just three months before the utility filed for Chapter 11 protection, that prohibits any transfer of a utility's generating assets until 2006.

Lawyers for the CPUC have been hesitant to insist on enforcement of some of these laws lest they might compromise the state's sovereign immunity and trigger a federal review of the state laws.
