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.

Japanese Ministry Supports Retail Deregulation of Power

LCG, Apr. 4, 2002--Japan's Ministry of Economy, Trade and Industry today heard from an advisory panel that "full liberalization" of electric power markets was a goal that should be gradually implemented and embraced by regional utilities, beginning with granting all retail customers the ability to choose a supplier.

The ministry, or METI, also made clear that unbundling of generation and transmission was not desirable for reasons of reliability, a stance that received approval from power industry representatives. Deregulation in North American and the European Union has been strongly linked to unbundling of services once provided almost entirely by vertically integrated utilities. Nonetheless, the president of Tokyo Electric Power Co., Nobuya Minami, said of the Federation of Electric Power Companies that its members "would like to discuss positively toward (the realization of) full liberalization."

The creation of a marketplace for wholesale power trading open to both traditional utilities and independent power producers, and intended to broaden diversity of power sources and increase efficiency, is an area that will be discussed by the panel during regular meetings. There was reported to be no consensus as to whether there should be an obligatory power pooling system or two-way trading.

While industrial and commercial users representing about 30% of power demand have been allowed to shop for a new supplier since March 2000, only 0.46% of such retail sales that could potentially be taking place through a new supplier are being realized. New competitors providing power pay significant fees to utilities for transmission and power reserves.
