Oklo completes end-to-end demonstration of advanced fuel recycling
Oklo Inc. has announced that it has completed the first end-to-end demonstration of its advanced fuel recycling process as part of an ongoing $5 million project in collaboration with Argonne and Idaho National Laboratories. Oklo’s goal: scaling up its fuel recycling capabilities to deploy a commercial-scale recycling facility that would increase advanced reactor fuel supplies and enhance fuel cost effectiveness for its planned sodium fast reactors.

The mapping ρn+1 = φ[ρn + kQ0(exp ρn — 1)] is shown to belong to the universal class of quadratic mappings with a negative Schwarzian derivative, thus rigorously providing the reasons underlying this mapping’s ability to follow the well-known Feigenbaum scenario to deterministic chaos. This scenario proceeds through an infinite cascade of period-doubling bifurcations, as noted in numerical experiments by Shabalin in a recent paper on power instabilities in periodically pulsed reactors. An analysis of this paper is also presented together with an overall perspective of the current state of research on chaotic dynamics in nuclear engineering systems.
