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.

Hearings Begin for Duke's New Coal-fired Units at Cliffside
LCG, January 18, 2007--The North Carolina Utilities Commission yesterday began a three-day hearing regarding Duke Energy Corp.'s plans to construct two coal-fired units at the Cliffside Steam Station. The hearing resulted from Duke's notifying the Commission that its cost estimate for the two, 800-MW units had increased from $2 billion to $3 billion.
In testimony provided yesterday, Duke witnesses further explained that the $3 billion cost excluded finance costs and that the total cost would be even higher.
The issues to be addressed by the Commission at the hearing are the accuracy of project cost estimate and whether the proposed project is the most economically feasible alternative. Duke anticipates a Commission decision by March. The first unit is scheduled to commence operations in 2011.
Duke originally filed its application with the Commission in May 2005 for a "Certificate of Public Convenience and Necessity" (CPCN) to expand and upgrade the Cliffside Steam Station, located in Rutherford and Cleveland counties, North Carolina.
In October 2006, Duke filed the revised, $3 billion estimate with the Commission on a confidential basis. In November 2006, the $3 billion cost estimate was released in response to pressure from opponents that were aware of Duke's filing a confidential cost update with the North Carolina Utilities Commission. The cost increase was driven by new, firm price quotes for major components of the planned facility.
The Commission had planned to rule on the CPCN for the new coal units by the end of 2006. With the roughly fifty percent increase in the estimated cost, the Commission scheduled the current hearing.
