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.

Progress in inertial confinement fusion development justifies an optimistic view of future concepts. The use of advanced fuels represents a key goal in obtaining future power plants. Prior work on such targets using a deuterium-tritium spark ignition is reviewed and evaluated via the conceptual reactor design LOTRIT. Preliminary calculations presented here also indicate that it may ultimately be possible to achieve a p-11B burn using a volume ignition. However, the parameters required, e.g., 105 times solid density, are beyond the reach of present technology.
