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 PSI-1 facility for studying plasma/wall inter-action is described. It uses a direct current arc as a plasma generator together with a hollow anode. The plasma expands through the anode into the target chamber and is confined by an axial magnetic field. The design values for the plasma parameters near the target are ne ≤ 1020 m−3, Te<50 eV, Γ ≤ 6 × 1023 m−2·s−1 and q ≤ 3.5 MW/m2.
