Oklo's Groves-2: DOE follow-on, medical isotopes first
Where it stands: Oklo has announced plans for Groves-2, the next stage of its Groves project under a follow-on DOE program, initially focused on medical isotope production. It named the planned Groves-2 Forge isotope production and processing pilot facility, which will build on the Groves Isotope Test Reactor that reached criticality earlier in 2026. What to watch next: the facility's site and partner, a dated construction and operations timeline, and isotope customers.

- 2026-10-19 (~5:24 AM ET, WNN — world-nuclear-news.org/articles): the Groves-2 track gains a facility name and a hardware foundation — Oklo says the Groves-2 Forge isotope production and processing pilot facility, planned under DOE's Launch Pad initiative, will build on the Groves Isotope Test Reactor, which reached criticality earlier in 2026. Development on the October 15 debut; site, partner, timeline, and isotope-customer detail still not in the reporting. Watch: facility scope beyond the name, site and partner, dated construction/operations timeline, isotope customers, Launch Pad mechanics.
- 2026-10-15 (first record, ~4:47 PM ET, ANS): Oklo announced plans for Groves-2, the next chapter of its Groves project, building on DOE Reactor Pilot Program progress and enabled by the follow-on Nuclear Energy Launch Pad Program, focused initially on medical isotope production (ans.org/news). Debut — no prior Oklo or Groves entry on the record. Announced plans, not construction: no site, partner, timeline, or isotope-customer detail in the reporting. Watch: site and partner for Groves-2, dated construction/operations timeline, Launch Pad Program mechanics vs the Reactor Pilot Program, isotope customers and economics in primary Oklo material.
