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.

Laser trackers are widely used in product inspection in the manufacturing process of the vacuum vessel (VV) for the China Fusion Engineering Test Reactor (CFETR). Due to the influence of temperature change on the geometrical properties of metallic materials, temperature change seriously affects the measurement accuracy of the workpiece. Therefore, temperature compensation is important to reduce the measurement errors caused by temperature change. This study uses 1/32 VV mockups as the research object. According to the results of finite element analysis and the onsite measurement results of the 1/32 VV at different temperatures, a method of temperature compensation for the 1/32 VV at different temperatures is summarized.
