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.

Allegheny Asks Permission for Special Borrowing

LCG, July 22, 2003--With its debt already relatively high compared to equity, Allegheny Energy Inc. is seeking to issue new notes that would be backed by regulated utility units, a move that may meet with resistance from the Securities and Exchange Commission.

The $2 billion worth of borrowing by the holding company would be used to sustain the unregulated arm of the company. The requirement regarding capital structure for a company owning utilities under the 1935 Public Utility Holding Company Act is to have at least 28% equity in order to issue securities, whereas in Allegheny's case it stands at 20%. The consequences if the request is not granted could be to undermine the utilities Potomac Edison Co. and West Penn Power, according to the public utilities commissions of Maryland and Pennsylvania. Those commissions have expressed their support of the SEC granting the request.

The Wall Street Journal quoted analyst Craig Shere, with Standard & Poor's, as saying that regulators have taken part in a "backlash" against increasing debt on the part of utilities due to fallout from deregulation. Allegheny owns utilities in Maryland, West Virginia, Virginia and Pennsylvania, and may sell more assets such as trading contracts according to its cash flow situation.
