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.

Implementation of changes in the U.S. nuclear fuel cycle for emerging needs such as high-assay low-enriched uranium, advanced fuel types, advanced medical isotopes, and plutonium processing will require new facilities and their associated processes and equipment. Integration of nuclear criticality safety (NCS) principles, limits, and controls should be incorporated early in the design process. This session will include papers which address the new strategies which may be employed to integrate NCS into the design process, operating experience and lessons learned from past design projects, and the associated risks and challenges faced by NCS practitioners during the design processes
