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.

Bulgaria Inks $1.4 Billion Contracts with Entergy, AES

LCG, June 13, 2001Bulgaria's reform government yesterday signed as expected $1.4 billion worth of electric power deals with two U.S. companies, AES Corp. and Entergy Corp. The signing is seen as bolstering the government's position in elections scheduled for this weekend.

Ivan Shilyashki, head of Bulgaria's energy agency, said "The large-scale investment of $1.4 billion is significant for Bulgaria's power industry." It is also significant for the incumbent government, as it is expected to create new jobs, improve the country's energy output and significantly reduce pollution.

Both projects are located in Bulgaria's Maritsa region, a lignite coal mining area. Lignite, also known as brown coal, is something between peat and bituminous coal, and presents a significant environmental challenge.

The project between Bulgaria's National Electricity Company and AES Corp. calls for a $900 million investment in a new 670 megawatt lignite-fueled power plant in the Maritsa East One area, replacing an old plant of smaller capacity.

Construction on the AES plant could begin late this year or in early 2002, according to Richard Mardon, who heads the company's operations in Central and Eastern Europe. The new facility is expected to provide 11 percent of Bulgaria's electricity.

The Entergy contract, also with the national Electricity Company, calls for a $470 million investment to upgrade and operate an existing 840 megawatt plant at Maritsa East Three. That project is expected to get underway later this year.

Geoffrey Roberts, chief executive of Entergy Wholesale Operations, said the project will improve reliability, add 20 years to the life of the plant and "preserve critical jobs in the region surrounding the plant and provide Bulgaria with a competitive source of electricity."

He called the project "one of the largest environment control efforts in all of Europe," and said it would cut emissions of sulphur gases and other pollutants by 90 percent at the plant.

Mardon said "We believe the two projects will attract significant amount of foreign investment into the country and also will provide significant environmental benefits."
