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.

Settlement Reached Between Ontario, Coral

LCG, Feb. 24, 2003--Coral Energy has paid C$1.6 million ($1.07 million) to Ontario's Independent Electricity Market Operator (IMO), while making "no admission of a breach of the market rules," according to the IMO website.

The settlement marks the largest such voluntary payment by an energy trader to the IMO. Neither Coral Energy nor IMO spokesmen would provide any information about what transactions were related to the settlement. According to Jimmy Fox, a Houston-based spokesman for Coral, the company did not gain financially from its trades, and did not manipulate the market.

The IMO coordinates the balance of demand and supply based on its monitoring of trades. It has investigated 106 trades that failed before execution during last summer, and has ceased looking into 41 of them. At least double the number of trades being investigated failed shortly after Ontario's retail market was deregulated. Retail price caps were imposed following price increases under deregulation that brought political pressure to bear on the government. The caps are due to expire in three years.

Critics of the return to regulation say that the move discourages investment in new generation, and will lead to a supply shortage and the need for Ontario to buy imported electricity at higher prices. The CEO of Atco Power, Nancy Southern, said last year that strong transmission links to the United States could enable new Ontario-based plants to export power profitably across the border.
