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.

San Jose Council Rejects Metcalf Energy Center

LCG, Nov. 29, 2000--The city council of the community that bills itself as the "Capital of Silicon Valley" voted early this morning to reject a 600 megawatt power plant proposed for a patch of land currently zoned partly for agriculture and partly for industry.

San Jose, Calif., Mayor Ron Gonzales doesn't believe there is a power shortage in Silicon Valley. "We want to understand what the needs are, and the alternatives, and potential other sites," he told a news conference yesterday before the Council meeting.

Apparently Mayor Gonzales has forgot the blackouts that hit close to 100,000 electricity customers in the South San Francisco Bay Area last June, when insufficient power caused a large substation to trip off line.

Calpine Corp., the big independent power producer that makes its home in San Jose, was unable to sway the populist local politicians and will have to rely on state regulators overruling objections to its proposed Metcalf Energy Center. The company was baffled by the "not in my back yard" attitude of its home town.

Lisa Poelle, a Calpine spokeswoman, said "If we don't get the opportunity to build this project, we'll be minus 600 megawatts of electricity in this town and, as the high-tech capital of the world, that's embarrassing." She said this morning's rejection was "just a bump in the road."

Among the biggest opponents of the Metcalf plant is Cisco Systems Inc., the number one computer networking company. Cisco is San Jose's largest employer and is building a 20,000-worker factory -- high-tech factories are called "campuses" -- on the same industrial-agricultural land and thinks the power it needs can be generated in Argentina.

Cisco scratched around and found some "experts" who would say the power plant isn't needed. It would be an eyesore, the "consultants" said, and it would pollute the whole area.
