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.

Former DOE Official Says Yucca Not a Strong Barrier

LCG, Feb. 7, 2002--The geologic formations at Nevada's Yucca Mountain are not as likely to prevent air and water pollution by radioactive waste as was once thought during early research on the potential nuclear waste storage facility, according to a former Department of Energy official.

Man-made containers used to store nuclear waste would provide most of the protection against leakage, John W. Bartlett stated in an affidavit released to The Washington Post. Bartlett headed a federal project for storing nuclear waste in Nevada for the Department of Energy from 1990 to 1993.

A DOE spokesman, Joe Davis, countered that the federal agency is committed to Yucca Mountain and has followed "the opinion of the scientific community as a whole in saying that man-made and natural barriers would ensure that we could protect the public if we built (the facility at) Yucca Mountain."

Bartlett, now a consultant to the state of Nevada, said that the DOE, in order to respond to Congress' emphasis on updated environmental standards in the selection of a storage site, had altered its "site suitability" rules so that prevention of contamination could depend more heavily upon the use of advanced storage containers.

In the affidavit, Bartlett said, "the project has become simply an array of engineered waste packages that happen to be located 1,000 feet underground." The DOE issued revised rules in December of 2001. In January, Energy Secretary announced that he would recommend Yucca Mountain as the best national site for nuclear waste storage to President Bush.
