The Client
American Electric Power – Cook Nuclear Plant
The Project
American Electric Power’s Cook Nuclear Plant, located in Bridgman, Michigan, needed to make repairs to prevent small groundwater leaks in the walls and floors throughout its Turbine Room, Screen House, and Auxiliary Buildings. To seal off the leaks, they planned to drill into the concrete walls and floors around the problem areas and fill the cracks with a special compound. However, because of safety requirements, all concrete needed to be imaged to locate all reinforcements and conduits before any drilling could take place.
The Plan
Diamond developed a plan to survey and scan all problem locations throughout the site. The plan involved using a Ground-Penetrating Radar (GPR) SIR 20 system with Radan software and on-site 3D capabilities to map and show the location of all subsurface objects.
The Process
Survey and verify the location of all reinforcement and utilities in the problem areas and map all findings to drawings for the team at Cook Nuclear. Using Ground Penetrating Radar would prevent the drills from making contact with rebar and conduit embedded in the concrete.
The Outcome
All maps and drawings developed for the Cook Nuclear Power Plan were completed to scale and submitted to the Plant’s Engineering Department. By verifying and showing the exact location of all reinforcement and utilities in the problem areas, the Cook staff avoided making destructive contact with rebar and conduit embedded in the concrete during the repair process.
