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.

Bush Signs Yucca Mountain Bill

LCG, July 23, 2002-Today President Bush made the Yucca Mountain into a national nuclear waste dumpsite, signing the bill regardless of considerable protest from Nevadans.

Yucca Mountain has been considered a possible repository for the nation's high level radioactive waste for over twenty years.

Some Nevada residents and environmentalists contend it has been the only site seriously considered and researched in that time.

In any case and despite a visit to the nation's capital by Nevada's governor, plans are to open the site by 2010. Nevada filed a formal protest earlier this year after President Bush announced his support for it, but both the U.S. Congress and Senate voted to utilize the site.

Yucca Mountain will accept some pre-existing 77,000 tons of radioactive waste, which is currently stored in 39 states across the country.

Opponents have cited safety concerns regarding the transportation of high level radioactive waste, although Energy Secretary Spencer Abraham has insisted that strict safety measures will ensure acts of terrorism or accidents will be avoided.
