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.

Koreas to Survey Power Sector on Entire Peninsula

LCG, Feb. 9, 2001North and South Korea agreed yesterday on a joint survey of the electric power systems covering the entire Korean peninsula, offering additional evidence of growing rapprochement between the two nations.

North Korea, on the second day of three-day talks held in its capital city of Pyongyang, had asked South Korea to begin sending electricity north as soon as possible. The North Koreans had earlier asked to receive 500 megawatts of power from the south.

Electricity shortages plague North Korea, where many homes and business are reported to be without power in the middle of the winter. Winters in North Korea are very cold, with temperatures as low as minus 30F not uncommon.

South Korean official say it would take four years to build the necessary transmission facilities and cost more than $600 million. The time and money could be better spent, they say, repairing generating facilities in the north.

South Korea expects the survey to show that North Korea has 7,300 megawatt of installed generation, but is capable of producing only 2,000 megawatts because of maintenance problems, obsolescence and fuel shortages.

South Korea said there was a possibility that it could ship surplus coal to North Korean plants.
