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.

Ireland has Plenty of Power for Winter, Official Says

LCG, Nov. 28, 2000--Irish Minister of Transport, Energy and Communications Mary O'Rourke said yesterday at the opening of the new $110 million, 120 megawatt peat fired station near Edenderry, County Offaly, that Ireland would have enough power to meet the demands for electricity over the peak winter season, the Irish Times reported this morning.

"The chairman has told me on behalf of the (Electricity Supply Board) that there is sufficient power," O'Rourke said. "This new plant, which is around six months ahead of schedule should also help the situation."

Peak demand in Ireland should reach between 3,900 and 4,00 megawatts this winter, according to Ted Dalton, ESB managing director for Irish Electricity. ESB could generate 4,500 megawatts, with the new Edenderry power station adding another 120 megawatts to the national grid, he told the Irish Times.

The new Edenderry plant is the first major power station to come on stream resulting from open competition and is the first significant power station of any kind since 1986. It is expected to act as a blueprint for two new peat fired generating stations to be built by the ESB in Shannonbridge and Lanesboro.

The new facility will provide 45 jobs and will consume one million tons of peat annually. Using fluidized bed peat combustion technology, the plant is generating electricity from peat sourced from Brd na Mna (the Peat Development Authority) and supplying it to the ESB under a 30 year contract.
