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.

NRG and MidAmerican Complete the 290-MW Agua Caliente Solar PV Project in Arizona

LCG, April 30, 2014-NRG Energy, Inc. (NRG), through its wholly-owned subsidiary NRG Solar, and its partner MidAmerican Solar yesterday announced they have achieved substantial completion of the Agua Caliente Solar Photovoltaic Facility, a 290 MW photovoltaic (PV) facility in Arizona. Pacific Gas & Electric Company (PG&E) contracted to receive the power generated by the facility under a 25-year power purchase agreement (PPA).

NRG Solar's president stated, "Large-scale utility accomplishments, like our Agua Caliente project, raise the bar in terms of our clean-energy technology and production. Proving that we can build both the world?s largest solar thermal and now one of the world?s largest solar photovoltaic facilities advance NRG?s mission to reshape the energy landscape that is incredibly beneficial to both the economy and in how we produce and consume energy. Whether it?s partnering, developing or investing, NRG will lead the way in providing a diverse set of solutions and technologies to get the US to the ultimate goal of providing affordable, reliable clean energy for everyone."

The Agua Caliente Solar Photovoltaic Facility site includes 2,400 acres of land located approximately 65 miles east of Yuma, Arizona. Agua Caliente is one of the first PV plants of this capacity to be connected to a 500kV transmission line. The project was designed and built by First Solar, Inc. using its advanced thin-film cadmium-telluride (CdTe) PV modules. FirstSolar will also operate and maintain the facility for NRG and MidAmerican Solar.

The project received a $967 million loan guarantee from the US Department of Energy?s Loan Programs Office.
