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.

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.

TVA and NuStart File Application for New Nuclear Reactors
LCG, October 31, 2007--The Tennessee Valley Authority (TVA) and NuStart Energy, a consortium of nuclear energy companies, yesterday submitted an application to the Nuclear Regulatory Commission (NRC) for a Construction and Operating License (COL) to build two nuclear reactors at TVA's Bellefonte site in northern Alabama. The new units would employ the Westinghouse AP1000 design.
Members of NuStart Energy consortium are: Constellation Energy, Duke Energy, Detroit Edison (membership pending), EDF International North America, Entergy Nuclear, Exelon Generation, Florida Power & Light Company, Progress Energy,South Carolina Electric & Gas, Southern Company, TVA, GE-Hitachi Nuclear Energy, and Westinghouse Electric Co.
The AP1000 reactor incorporates passive safety features that rely upon natural forces. The NRC approved the Design Certification for the AP1000 standard nuclear plant design on December 30, 2005. Other companies that have announced the selection of the AP1000 design as the basis for additional COL applications to construct reactors include: Progress Energy, Southern Company, Duke, SCANA and Santee Cooper.
NuStart and Dominion are also developing the reference application for the GE-Hitachi Nuclear Energy (GEH) Economic Simplified Boiling Water Reactor (ESBWR), which also employs passive safety features. NuStart expects Dominion to file the application with the NRC for a single unit at its North Anna Power Station later this year, and the application will support subsequent, planned COL applications by Entergy for its Grand Gulf and River Bend sites next year.
In addition to the applications relying upon the Westinghouse and GEH designs, Unistar Nuclear, a joint venture of Constellation Energy and AREVA Inc., in July 2007 filed with the NRC the environmental report portion of a COL application to build a reactor that uses AREVA's 1,600-MW, U.S. Evolutionary Power Reactor (US EPR). The US EPR is based upon AREVA's 1,600-MW, European EPR that is now being deployed in Europe. The new reactor would be built adjacent to Constellation's existing Calvert Cliffs nuclear power plant in Lusby, Maryland.
