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 simplified boiling water reactor makes use of an isolation condenser (1C) submerged in a large water pool; following a postulated accident, the pool water boils off, releasing steam to the atmosphere and ensuring passive containment cooling for at least 3 days. A further improvement is the isolation condenser pool cooling system (ICPCS), proposed by ENEL /CISE. It makes use of reflux condensing heat exchangers directly connected to the pool gas space of the IC; noncondens-able gases can be vented during the earlier phase of operation by means of a water seal mechanism operating in a passive way. The expected benefits from the ICPCS are the elimination of constraints on the “grace period” duration and the possibility of avoiding an extended release of a visible and potentially radioactive steam plume. To verify the performance both at component and system level, an instrumented ICPCS prototype, operating with a thermal power scaling factor of ∼1:615, has been built and tested at CISE laboratories, both in steady and dynamic conditions. The experimental results confirm the capability of the tested ICPCS module to operate in a safe and passive way.
