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.

Cal Power Authority may be Losing

LCG, Nov. 28, 2001--The California Power Authority, created earlier this year to build, own and operate new power plants as insurance against electricity outages, now says it probably won't need those power plants.

The new agency, headed by S. David Freeman, has halted negotiations to build by next summer 31 proposed projects with a combined capacity of 3,200 megawatts.

"It's looking less and less likely that these projects will be needed by next summer," said Amber Pasricha, a power authority spokeswoman.

On November 20, the California Energy Commission issued its 2002 Monthly Electricity Forecast which predicted that the state next summer will have a supply surplus of approximately 340 megawatts including new generation of 4,000 megawatts expected on line by July 2002.

A forced outage at any baseload power plant could plunge the state into another electricity deficit, resulting in rolling blackouts. A surplus of 340 megawatts in the control area of the California Independent System Operator represents a "cushion" of less than 1 percent, while most power professionals consider a reserve of 15 percent to be prudent.

Much of the state's power supply for next year and for up to 20 more years is in the form of long-term contracts negotiated by the California Department of Water Resources at an average cost of $69 per megawatt-hour -- more than twice today's going price.

Consumer advocates and state regulators want to see those contracts renegotiated, but the power producers are loath to accommodate them.

Now, Freeman sees a way to put the $5 billion funding for his agency to good use, if it isn't going to build power plants. He said the power authority could use its money to provide low-cost financing to companies already doing business with the state as an incentive for the companies to renegotiate their contracts.
