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).

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.

Williams Has Deal With Buffett and Banks

LCG, Aug. 1, 2002--An agreement between troubled William Cos. Inc., investor-billionaire Warren buffett and Lehman Brothers to sell oil and gas assets it bought only last year allows Williams to increase its total borrowing capability and improve its cash situation.

Buffett's Berkshire Hathaway Inc. and Lehman Brothers provided a $900 million senior secured credit agreement (senior being a higher level of obligation than junior). In return, MidAmerican Energy Holdings, under Berkshire Hathaway, receives preferred stock in Williams. Hugh Welton, a senior director at Fitch Ratings, a credit-rating agency, said, "it's pretty spectacular the amount of stuff they've done in a week, though it's been at the expense of selling some good assets that have contributed to their earnings profile."

Aside from the Buffet-Lehman Brothers deal, $1.1 billion of credit was secured through an existing line of $700 million, plus $400 million in new credit. Some of the other asset sales made by Williams included a $350 million sale of Wyoming natural gas assets to Encana Corp., and nearly all of its gas-related holdings in the Anadarko basin to Chesapeake Exploration LP, for $37.5 million.

Other energy companies have been worried at what was the very real prospect of a credit default this week by Williams, which would have contributed to a more dismal outlook for those companies already trying to improve fallen credit ratings. Dynegy this week sold its Northern Natural Gas pipeline to Buffett for $928 million.
