  Oklo Inc. is a Santa Clara, California advanced fission company designing
  and deploying small modular reactors under the Aurora powerhouse brand.
  The Aurora is a liquid-metal (sodium) cooled, metal-fueled fast reactor
  derived from the Experimental Breeder Reactor-II (EBR-II) lineage,
  engineered as a "walk-away safe" passively cooled system that is
  self-stabilizing and self-controlling under loss-of-coolant and
  loss-of-shutdown conditions. Oklo's reactors are intended to run on
  recycled high-assay low-enriched uranium (HALEU) fuel, including legacy
  EBR-II material, with the company building out three vertically
  integrated fast-reactor businesses: clean power generation, advanced
  nuclear fuel fabrication and recycling, and medical radioisotope
  production. The first commercial Aurora is targeted for operation at
  Idaho National Laboratory (INL) in late 2027 to early 2028, supported
  by selection into the DOE Reactor Pilot Program and Fuel Line Pilot
  Projects, and the company has completed an NRC Phase 1 pre-application
  assessment. Oklo went public in May 2024 via merger with AltC
  Acquisition Corp (a SPAC co-founded by Sam Altman, who serves as
  chairman) and trades on the NYSE under ticker OKLO. Oklo's commercial
  posture is utility-scale and industrial — selling power, fuel cycle
  services, and isotopes to data center operators, defense customers,
  and industrial offtakers — and the company exposes no public developer
  API, SDK, or open source software.
