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 Tritium Systems Test Assembly (TSTA) has been operating for 4 years with tritium inventories of up to a million Ci and a cumulative (circulated) throughput of over 10 billion Ci to date. During the operational life of the facility 40,000 Ci of HTO waste have been intercepted by the tritium waste treatment system. Stack releases for the 4-year period have totaled < 40 Ci, and exposure to operating personnel has been < 3 mREM/person/yr. This excellect record is due in large part to high priorities placed on tritium-safe design concepts, but real-time computer diagnostics have been equally important in enabling us to anticipate and prevent potential releases of tritium.This work is supported by the US Department of Energy, Office of Fusion Energy.
