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.

A detailed evaluation of the electromechanical force distributions in the vacuum vessel of the IGNITEX device during major plasma disruptions is presented. The effects of the disruption plasma conditions, the single-turn toroidal magnet system, and the vessel resistivity are discussed. The electromechanical stresses are evaluated and stress distributions are presented. It is shown that the electromechanical forces due to plasma paramagnatism are comparable to the usual forces due to the plasma toroidal current. The stress analysis is performed for the proposed IGNITEX vacuum vessel.
