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.

Because of twenty five years of tritium experience in the Bruyères-le-Châtel Center (CEA-FRANCE), new activities could be recently undertaken inside the European Fusion Technology Program, especially, tritium studies within the frame work of the Next European Torus (NET). After indicating generalities about our tritium experience in various areas, these following studies are after examined: purification of deuterium-tritium mixtures (DT) by cryosorption on molecular sieves, purification of DT on uranium beds, storage of DT on Lanthanum-Nickel-Manganese, weldability of tritium-helium implanted materials and corrosion of materials by “tritiated waters” species.
