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.

Major disruptions are an important impediment to improve tokamak plasma performance and a critical design consideration of tokamak ignition devices. Ignited plasma disruptions are studied in the IGNITEX experiment. A two-phase (energy quench followed by current decay) disruption is phcnomenologically simulated and its effects on the conducting structures are analyzed. Various disruption conditions are studied. The effects of the single-turn TF magnet system are taken into account. The implications on the IGNITEX machine design are discussed.
