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.

South Korea Plans 10 More Nukes

LCG, July 12, 2001The Republic of Korea said in Seoul yesterday that it plans to add 10 new electric power nuclear reactors over the next 10 years to keep pace with growing electricity demand.

Nuclear power plants now supply 40.9 percent of South Korea's electricity, and that percentage won't grow under the program. The addition of the new plants, which will have a combined capacity of 10,800 megawatts, will barely cover expected increases in demand.

Prime Minister Lee Han-dong is chairman of a special government committee which announced the plan to complete two new reactors next year, another two in 2006, two more in 2008 and another four by 2011.

A spokesman for the Ministry of Science and Technology said some of the reactors are already under construction. Eight will have a generating capacity of 1,000 megawatts each and the other two will produce 1,400 megawatts of power.

In 2011, when the program is complete, South Korea will have 24 reactors producing about 40 percent of the nation's electricity. The prosperous south of the Korean Peninsula has the industrial capability to construct nuclear power plants without outside help.
