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.

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.

Lake Michigan Silt Closes AEP's Cook Nuke
LCG, Aug. 30, 2001--American Electric power Co. said this morning that the 1,100 megawatt Unit 2 of its Cook nuclear power plant at Benton Harbor, Mich., was being taken off line because of the intrusion of Lake Michigan silt into its cooling water systems."The silt was drawn in by plant water intake pipes and degraded cooling water systems required for plant safety equipment and back-up power sources," AEP said in a statement.Silty water is a fine abrasive and can literally grind down the moving parts of a system in which it circulates. AEP said Unit 1 at Cook, a twin of Unit 2, was taken off line on Monday to replace a circulating water pump discharge valve. The company did not say silt was what made the replacement necessary but did say that silt intrusion affects the cooling water systems for both units.Three huge pipes, each 16 feet across, bring water from one-half mile out in Lake Michigan into the plant. It is not surprising that silt -- and an occasional boat -- would find its way into the plant's systems.AEP was unable to say how long the units would be shut down, but said return-to-service schedules for both units will be established following an investigation to determine the cause of the silt intrusion.
