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.

An outline of Next European Torus safety and its impact on the environment is presented. Included are a short characterization of the basic safety approach, current radiological recommendations, and the potential hazards due to tritium, neutron-induced radioactivity, and energy inventories. Significant accidents that could be initiated and propagated by these energies and finally lead to releases of radioactivity are characterized by typical initiating events such as after-heat under loss-of-cooling conditions and ruptures of blanket components. The environmental impact of releases is dealt with by reporting experimental results on tritium behavior in the environment as well as by broadly quantifying tritium dispersion and activation product releases under both routine and accidental conditions. Finally, the categories of wastes produced, their approximate amounts, and a strategy for their final disposal are presented.
