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 Fusion Power Plant Planned for Japan

LCG, Dec. 26, 2000The Japanese Atomic Energy Commission said this morning that an experimental nuclear fusion power plant developed jointly with western European countries and Russia would be built in Japan, according to Kyodo News Service.

Nuclear power plants such as those in the United States operate on the principle of atomic fission, in which atoms of uranium are split when bombarded with neutrons. The chain reaction creates heat which, in turn, is used to make steam to spin turbines which drive electric generators.

Nuclear fusion is, on the other hand, the combining of atoms and reactions are called thermonuclear because they take place in the presence of great heat. Scientists believe that the sun creates energy by fusing light elements such as hydrogen with heavier ones, releasing energy and visible light.

Japan is to become the land of the rising sun.

The installation of the International Thermonuclear Experimental Reactor is likely to draw protests in Japan, although Kyodo noted that three communities, Tomakomai in Hokkaido, Rokkasho in Aomori Prefecture and Naka in Ibaraki Prefecture have already declared themselves willing to host the project.
