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.

A relatively simple and inexpensive fusion ignition experiment is described. The experiment can be realized in a single-turn tokamak powered by homopolar generators. The discharge will proceed by ohmically heating a DT plasma to over 3 keV and then by using alpha heating to produce a stable ignited phase of operation. The technologies required for the realization of the experiment are in hand. A fulltorus, IGNITEX toroidal field magnet prototype has been operated to date at 15 Tesla. This record value in toroidal magnets establishes the possibility for ohmic ignition. The magnet prototype is scheduled for operation at 20 Tesla levels later this year. Various physics and engineering characteristics that contribute to the simplicity and low cost of the IGNITEX experiment are discussed. The IGNITEX concept has the potential to make a significant contribution to the development and study of fusion in the near term.
