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.

Implantation-driven permeation (IDP) behavior of deuterium implanted with low energy (100–1800 eV) into 304 stainless steel has been studied. The experimental results showed that steady state permeation fluxes of deuterium through 304 SS decreased significantly with increasing the D+ ion from 100 through 1000 eV, while those above 1000 eV little depended on the energy. The energy dependence of the permeation flux observed would be attributed to change of the rate-determining regime of the permeation process depending on the incident ion energy.
