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.

National Guard on Duty at Four More Entergy Nukes

LCG, Nov. 1, 2001--Entergy Corp. said yesterday that three southern states have ordered National Guard troops to pull guard duty at four of its nuclear power stations, following a warning by U.S. Attorney General John Ashcroft of possible new terrorist attacks.

Entergy, which is the third-largest U.S. power generator, said it had asked for the National Guard troops because of a generally heightened state of alert. "This involves no specific threat but there is a general credible threat against nuclear facilities and we are taking what we believe are appropriate precautions," spokesman Phil Fisher said.

The National Guard was called out to protect Entergy nuclear plants in Arkansas, Louisiana and Mississippi. Similar action was taken last month to protect Entergy nukes in New York and Massachusetts.

The company said it had initiated discussions with the governors of the three southern states following Ashcroft's warning Monday that terrorist attacks may be carried out in the next week against unspecified U.S. targets at home or overseas.

The office of the governor of Arkansas said in a statement "In response to concerns about terrorist threats, Entergy has requested assistance from Gov. Huckabee and the Arkansas Department of Emergency Management to increase security at Arkansas Nuclear One," a two-reactor plant about 70 miles northwest of Little Rock.

Fisher said "We have no reason to believe that any attack is planned against Arkansas Nuclear One or any other nuclear plant that we are aware of."

But everyone will feel better with a few platoons of armed men wearing camouflage fatigues walking the perimeter of Entergy's nuclear power plants.
