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.

Hydrogen depth profiles have been measured for stainless steel pre-irradiated with 10 keV helium ions with fluences close to the critical fluence, Fc. The hydrogen retention was stable with time at room temperature for the fluence above Fc. The retention was composed of the decay and stable components for the fluence below Fc. The annealing up to 400 °C indicated the same release behavior for the fluences below and above Fc.
