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.

Estimates of the ARIES-I current and fusion-power rampup have been made using a profile-averaging, plasma/circuit simulation model. For the case of a combined inductive and rf-assisted startup, a minimization of non-inductive startup power needed to supply both resistive and inductive magnetic-flux requirements generally favors a low-density current rampup, which is then followed by a DT fueling schedule that brings the plasma to full fusion power.
