Oklo Advances Aurora Reactor with Siemens Energy Contract

Oklo (OKLO) rose 5% pre-market after announcing a binding agreement with Siemens Energy (SMEGF) to design and deliver the power conversion system for its first Aurora nuclear powerhouse, located at the Idaho National Laboratory.

The deal enables Siemens Energy to begin engineering work immediately, helping secure long-lead components and reducing timeline risks for the advanced reactor project.

What the Contract Includes

Siemens Energy will undertake detailed engineering and layout work for several major systems:

Condensing SST-600 steam turbine
SGen-100A industrial generator
Auxiliary components needed to support Aurora’s power conversion process

These components form the core of the power system required for Oklo’s first commercial reactor.

Why This Matters for Oklo

The power conversion system represents a major long-lead procurement milestone for Aurora. With fuel material and the Idaho site already allocated, securing this contract:

Reduces supply chain uncertainty
Strengthens Oklo’s project execution timeline
Moves the Aurora powerhouse closer to commercial power operations

Oklo emphasized that the agreement demonstrates tangible progress toward deploying next-generation fission technology.
