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.

For the establishment of liquid-metal-cooled fast reactors (LMFRs) as commercial reactors, one of the most important tasks is to develop highly reliable heat transfer tubes for steam generators used in LMFRs because their failure could lead to a potentially explosive sodium/water reaction. A new concept for a highly reliable duplex tube heat transfer system is proposed as an improvement over the defects of the contact-type duplex tubes and knitted wire-packed ones, which have been proposed. Small-scale duplex tubes have been manufactured. Their heat transfer rates were investigated experimentally, and an evaluation method of their effective thermal conductivity, which is required for design purposes, is proposed, where the change in contact resistance due to thermal expansion is a consideration.
