State-of-the-Art of Non-Destructive Testing Methods and Technologies for Application to Nuclear Power Plant Safety-Related Concrete Structures
- Federal Institute for Materials Research and Testing (BAM)
- ORNL
The inspection of nuclear power plant concrete structures presents challenges different from conventional civil engineering structures. Wall thicknesses can be in excess of one meter and the structures often have increased steel reinforcement density with more complex detailing. The accessibility for any testing method may be limited due to the presence of liners and other components and there can be a number of penetrations or cast-in-place items present.The objective of the report is to present the state-of-the art of non-destructive testing methods and technologies for the inspection of thick, heavily-reinforced nuclear power plant concrete cross-sections with particular respect to:•locating steel reinforcement and identification of its cover depth•locating tendon ducts and identification of the condition of the grout materials•detection of cracking, voids, delamination, and honeycombing in concrete structures•detection of inclusions of different materials or voids adjacent to the concrete side of the containment liner•methods capable of identification of corrosion occurrence on the concrete side of the containment liner
