Question · Q3 2025
Ted Dore with Citi inquired about the Pluto test reactor, asking if it would serve as a template for future reactors, its differences from Aurora (e.g., plutonium fuel, 75 MW size), and the main learnings Oklo expects to gain. He also asked for a directional dollar breakdown of CapEx by components, as presented on slide nine.
Answer
CEO Jacob DeWitte clarified that Pluto is a smaller, bespoke system for fast neutron irradiation testing, not a template for power reactors. It's optimized for plutonium and fast neutrons to gain experience in plutonium criticality, handling, and fuel fabrication, serving as an R&D platform. CFO Craig Bealmear stated that dollar breakdown for CapEx would directionally align with component numbers, with more detailed estimates expected in 2026 after further procurement and Kiewit's involvement.
