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.

Strict control over tritium production and inventory must be obtained by any electrical utility operating a magnetic confinement fusion reactor plant if they do not want to be in the business of tritium production beyond the requirements for their own plants. A computer model has been developed to analyze the tritium inventory in a multiple compartment tritium handling system. Analysis has been conducted to explore a variety of reactor system operational parameters and modes including the effects of varying the TBR to achieve a constant storage inventory, the effects of actual operational cycles including an annual down time for blanket replacement, and the effects of failures of various components within the tritium processing stream.
