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.

Washington Okays Avista Cost Recovery Plan

LCG, May 25, 2001--The Washington Utilities and Transportation Commission has approved an unopposed settlement agreement reached last month between Avista Corp., the staff of the WUTC, the Public Counsel Section of the Washington Attorney General's Office and the Industrial Customers of Northwest Utilities.

Under the agreement, Avista will be able to extend to February 2003 a deferred accounting method that will allow it to weather a period of power shortages without increasing rates to its customers, the company said this morning.

Avista said it expects to be in a surplus power position next year and the revenues from surplus power sales are expected to offset power costs the company has been incurring since July of last year. The company said it anticipates reducing the power-cost deferral balance to zero by the end of February 2003.

In its order, the commission said "Our approval of the Settlement Stipulation offers significant potential that Avista will not seek any increase in rates to its customers related to power supply costs despite the volatility of wholesale power markets in our region during recent periods."

Gary G. Ely, Avista's chief executive, said his company has "worked extremely hard to shield our customers from the substantial electric rate increases that others throughout the region are already experiencing."
