Oklo is currently targeting its first Aurora powerhouse at Idaho National Laboratory to begin operation in late 2027 to early 2028, with some reporting also describing 2027 as the first online year and others saying early 2028.

What that means

  • Oklo has not finished building a reactor yet.
  • Its public timeline points to construction and deployment finishing around late 2027 or early 2028, depending on licensing and build progress.
  • Earlier coverage also said Oklo expected a commercial-scale Aurora reactor in 2027.

Quick read

If you want the shortest answer: late 2027 to early 2028 is the best current estimate for Oklo’s first reactor to be finished and operating.

Why it can shift

Nuclear projects often move with licensing, site work, fuel readiness, and construction milestones, so the date is still a target rather than a guaranteed finish date.
