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 prerequisites and mechanism for the implementation of efficient pulsed (flashing) nuclear fusion in a low-temperature hydrogen plasma with a temperature of 10 to 20 eV in a constant magnetic field are considered. It is shown for the first time that the natural very frequent alternation of the processes of ionization of atoms and recombination of ions leads to the synchronous formation of coherent correlated states of hydrogen nuclei and its isotopes. The formation of such states leads to the generation of very large fluctuations of kinetic energy (up to 10 to 100 keV) at the initial stage of each ionization event, which exists for most of the lifetime of the ionized state before ion recombination. It is shown that the relatively long duration of the existence of these fluctuations and their very large amplitude are sufficient for efficient nuclear fusion in such a magnetized low-temperature plasma.
