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.

Concern about possible radiation damage from the increasing exposure of memory disks to mild radiation environments prompted an experimental investigation into this matter. A series of programmed memory disks were exposed at near room temperatures and in an air environment to several types and intensities of radiation, with stored data retrieved before and after exposure. Initial separate exposures to alpha, beta, gamma, and neutron radiation were in the range of 5 to 15 mrad, the “upper limit” of radiation exposure that might be expected in common usage situations. Finding no permanent damage, the disks were then subjected to high-level 60Co gamma radiation to total doses up to 20 Mrad, again with no detectable postirradiation effects. Finally, the disks were subjected to high-level neutrons (up to 2.86 x 1011 n/cm2 total thermal neutron fluence) as well as to gammas in a research reactor. Postulated radiation damage mechanisms apparently were not consequential. It is concluded that in the range investigated, radiation damage to memory disks is not significant to their ability to function.
