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.

AES to Build 670 Megawatt Plant in Bulgaria

LCG, Oct. 18, 2001--A joint venture between AES Corp. of the U.S. and Bulgaria's government-owned National Electricity Company said this morning that AES would begin construction next May of a 670 megawatt coal-fired power plant at the Balkan country's Maritsa East coal mining complex.

AES will invest $225 million of its own funds for an undisclosed share of the project, the joint venture said in a news release. Another $625 million in funding is expected from the European Bank for Reconstruction and Development, U.S.-based Overseas Private Investment Corporation and Germany's Kredit fur Wiederaufbau.

Bulgaria has profited recently from exports of electric power, gaining $150 million last year from power deals with Turkey, Greece, Macedonia and Yugoslavia. But as much as 40 percent of the nation's generating capacity is slated for decommissioning or overhaul by 2010, which could limit supply available for export.

The new plant is aimed at heading off that problem before it occurs.

The project is also expected to reduce Bulgaria's dependency on coal imports from Russia and Ukraine.
