Deep geologic repository progress—2025 Update
Editor's note: This article has was originally published in November 2023. It has been updated with new information as of June 2025.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.

Air detritiation dryers at fusion facilities require high detritiation factors to minimize environmental releases. To increase the detritiation factor in air dryers, we have investigated a technique of eluting the residual adsorbed tritiated water on a molecular sieve bed that uses H2O steam washing during regeneration. The method relies on additional detritiation of the air stream occurring through isotopic exchange between the tritiated water vapor passing through a dryer bed with previously adsorbed non-tritiated water. Isotopic exchange is studied in both an operating industrial-scale air dryer, where the bed has been pretreated to remove tritium, and in a small laboratory bed. A mathematical model is presented to quantify the isotopic exchange process.
