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 paper describes the technology of creating a surface source of high-energy tritium ions and alpha particles formed as a result of a nuclear reaction of the interaction of the 6Li isotope with thermal neutrons .
Different design versions of the developed irradiating ampoule devices are presented, and a description of the experimental reactor facility is given. The paper also describes the scheme of reactor experiments to study the spectral-luminescent characteristics of nuclear-excited plasma of argon. The results of test experiments are presented, and they show the applicability of high-energy tritium ions and alpha particles for nuclear excitation of luminescence of inert gas mixtures.
