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.

Zachry Nuclear is a full service engineering firm that has been providing engineering, design, software development, and operations & maintenance (O&M) support services for electric utilities, advanced reactor designers, research organizations, regulators, Architect/Engineers, fuel vendors, and government energy agencies worldwide for over 45 years. Zachry Nuclear, and predecessors, Proto-Power Corporation (PPC), Numerical Applications, Inc. (NAI) and Computer Simulation & Analysis, Inc. (CSA), are internationally recognized for our expertise in thermal hydraulics analysis, radiological analysis, safety analysis and software development. We develop several industry standard analysis codes such as GOTHIC (coarse grid CFD), RETRAN-3D (system thermal-hydraulic and 3D neutron kinetics), VIPRE (subchannel), PROTO-FLO (piping analysis and design), PROTO-HX (heat exchanger performance), RADTRAD-NAI (dose and radiological consequences) and also develop custom software solutions. We specialize in applying these and other tools to provide significant cost savings for our clients through efficiency improvements, margin recapture, operations flexibility, and effective designs by developing innovative engineering solutions through automation, optimization, advanced modeling and simulation and machine learning methods. Our clients include existing plants and advanced reactor vendors supporting many of the SMR, non-LWR and microreactors currently being designed and developed both in the US and internationally.
