Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

Nuclear Agency Criticizes Its Treatment of Ohio Reactor

LCG, Jan. 3, 2002--A unit of the Nuclear Regulatory Commission has found that the agency's staff put off shutting down the Davis-Besse nuclear plant in Ohio, due to owner FirstEnergy's concerns that its earnings would be impacted if Davis-Besse were to shut down before a scheduled outage.

A report by the Office of Inspector General found that inspectors for the agency were aware that they might find leaks caused by cracks in the reactor's lid, and that there was "strong "justification" for ordering the plant shut down in 2001. FirstEnergy warned the NRC that there could be power outages if the plant were to be shut down before February 2002, and apparently persuaded the agency not to order further inspections before regular maintenance.

In the view of Rep. Dennis Kucinich, the report, which was obtained before public release, show that "FirstEnergy and the NRC worked together to put profits above public safety. It's unacceptable."

The chairman of the NRC, Richard Meserve, has 90 days in which to make a formal response to the Office of Inspector General report. He told The Plain Dealer that the conditions at the plant were uncertain, and that inspectors made a reasonable decision given what they knew. "Safety is in fact our highest priority," he said.
