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 head of a cylindrical reactor vessel must be designed for earthquake-induced sloshing force if there is insufficient freeboard. Herein, a design-oriented calculation method is developed for base-and head-supported annular tanks, where the annulus separates the reactor vessel and its core barrel. Charts are provided to enable preliminary design calculations. Examples are presented to describe the calculations.
