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.

The tritium gas obtained from a tritium production campaign was analyzed with a practical radiogas Chromatograph, which enabled one to make successive determination of the chemical and isotopic purity of the gas. The calibration of thermal conductivity detector for hydrogen gases showed that sensitivities of detector were H2>HT>T2 in that order. The chemical and isotopic purity of the tritium gas produced was determined to be 99.0% and 93.6%, respectively.
