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 Receives Approval from California Energy Commissioners to Construct Gas-Fired Power Generation in Southern California

LCG, April 13, 2017--California Energy Commissioners yesterday approved plans to construct and operate a power generation facility, the Huntington Beach Energy Project (HBEP), located in the City of Huntington Beach. The 844-MW, natural-gas fired project will be developed by AES Southland Development, LLC (AES).

The Commissioners had approved a larger version of the Huntington Beach plan in October 2014. AES requested permission to alter its plans the following year. The California Energy Commission (CEC) is the lead agency for licensing thermal power plants 50 MW and larger under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA.

The HBEP will be located within the footprint of the existing Huntington Beach Generating Station, an operating power plant constructed in the 1950's. The HBEP will include a 644-MW combined cycle power block, as well as two 100-MW simple cycle units. The combined cycle block is planned to commence operations in 2020, and the other units are planned to begin operations in 2024.

California Energy Commissioners also approved another proposal from AES to construct the Alamitos Energy Center (AEC), located near Long Beach's eastern boundary. The proposed facility will include a nominal 640-MW, natural gas-fired, combined cycle power block and four, 100-MW, simple cycle units. The electric generation equipment would be installed on approximately 21 acres of the existing 71-acre site, where Alamitos Generating Station Units 1-6 currently provide a net generating capacity of 1,950 MW.

AES submitted its original application to modernize the existing Alamitos Generating Station on December 27, 2013. AES amended its application in September 2015.

AES plans to decommission the existing power plants to comply with a 2010 California regulation constraining the use seawater for cooling at the plants.
