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.

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.

Dominion Selects Mitsubishi for New Reactor in Virginia
LCG, May 12, 2010--Dominion Virginia Power announced Friday that it selected Mitsubishi Heavy Industry's Advanced Pressurized Water Reactor (US-APWR) design for its new nuclear reactor sited adjacent to the existing two reactors at the North Anna Power Station, located approximately 60 miles northwest of Richmond, Virginia.
Dominion's announcement stated that it has not yet decided to build a new nuclear unit at North Anna, but expects to make a decision later this year.
The Mitsubishi US-APWR design is now undergoing the Nuclear Regulatory Commission (NRC) certification process.
The chairman, president and chief executive officer of Dominion, the parent company of Dominion Virginia Power, stated, "Dominion Virginia Power is the first utility in the United States to conduct a competitive bidding process for new reactor technology in the past decade. We are pleased with the results of this process. Based on our final analysis of the proposals received in the competitive process, Mitsubishi provided the most attractive value for our customers."
In November 2007, Dominion received an early site permit (ESP) from the NRC for the new reactor. The ESP stated that the site is suitable for a third reactor and provided for a 20-year option for Dominion to consider adding the reactor. Dominion also filed an application with the NRC for a Combined Operating License (COL) to construct and operate the third nuclear reactor at the North Anna Power Station. When the application was filed, it was expected that Dominion would use the GE-Hitachi Nuclear Energy (GEH) Economic Simplified Boiling Water Reactor (ESBWR) design.
