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.

Displacement Gas Chromatography will be used at JET to extract pure T2 and D2 from mixtures of H2, HD, HT, D2, DT and T2. This method makes use of strong isotopic effects in the β-phase of the Pd-Qa system. Designed for a daily throughput of ∼20 moles of isotope mixtures, the system will incorporate four individual separation columns, each containing ∼ 5ℓ packing of palladium on a porous alumina substrate. The main parameters, operation seguences and design principles are discussed.
