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 design of target chambers for the Inertial Confinement Fusion (ICF) Laboratory Microfusion Facility (LMF) requires a good understanding of the pressure loadings experienced by the chamber walls. Beam transport, diagnostics, and LMF applications place severe constraints on the chamber fill gas; in current light ion beam concepts only 1.5 torr-meters of helium are between the target and the closest target chamber structures. Simulations of the unavoidable vaporization of the first wall have been performed with the CONRAD computer code for a light ion beam LMF concept. Results show that the peak pressure on the wall is a function of the target x-ray power density on the wall, while the impulse on the wall is a function of x-ray fluence.
