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.

Heat of transports Q* of hydrogen isotopes in the α-phase of Zr have been measured in temperature regions from 623K to 673K for H and from 523K to 623K for T by analysing the redistribution process under a thermal gradient. An isotope mass dependence of Q* has not been unequivocally established though a tendency that Q*(H)>Q*(T) has been observed. These data have been discussed on the basis of the biased-jump diffusion model, and a large negative bias effect has been pointed out as characteristics of Q* of hydrogen isotopes in group-IV metals in comparison with the case of group-V metals.
