Oklo's plan to turn leftover weapons-grade plutonium into a nuclear bridge fuel

Calling plutonium a bridge fuel to HALEU is such a crazy thing to say. Plutonium is derived from Uranium-238, which is 99.3% of natural uranium. HALEU is enriched U-235, which is 0.7%. There's no large-scale nuclear future running on HALEU. It's always either been plutonium derived from U-238 or U-233 derived from thorium.
