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.

North Korea Nuke Experts End Tour of South

LCG, Dec. 31, 2001--A group of 20 North Korean nuclear engineers concluded over the weekend a tour of South Korean nuclear power plants as part of the 1994 agreement between the United States and North Korea under which an international consortium will build two light-water reactors in the North and train hundreds of workers to operate them.

As part of the agreement, North Korea has promised to freeze its nuclear weapons program, which should be easy because at this time of the year, everything freezes between Pusan on the southern tip of South Korea and the Yalu River border between North Korea and China.

We lived in Korea during the winter of 1952-53 -- were camped out, actually -- and it was 30F below zero most of the time.

The engineers, led by Kim Hui-moon, a Cabinet-level official, visited Ulchin, an east coast village where four French-built nuclear reactors are in operation, and Kori on the south-east coast for a tour of four US-built reactors, according to BBC News.

By the end of the coming year, South Koreans will have trained about 290 North Koreans in the operation of U.S. designed pressurized water reactors, which will replace North Korea's Soviet-designed graphite moderated reactors, which produce large amounts of weapons grade plutonium.

North Korean workers, visiting the prosperous south, have seen how 50 years of freedom has transformed South Korea and have demanded higher wages at the North Korean project, delaying it. As its energy crisis has deepened, the North has threatened to abandon the 1994 accord and has demanded that Washington pay compensation for the delays.
