Work in this area concerns the safe and reliable operation of nuclear power plants and NASA’s space shuttle. Existing challenges to characterize and size various forms of complex cracking in steam generator tubes from nuclear plants could be minimized by selecting appropriate eddy-current probes and analyzing the generated data by specially developed computer algorithms. The improved reliability in in-service inspection will lead to more efficient generation of electricity, helping to maintain nuclear plant capacity by reducing the chance of an unscheduled shutdown caused by improper assessment of complex cracks. In addition, results will help eliminate needless plugging of steam generator tubes by improved understanding of inspection results and their importance. We are also developing eddy current technology for detection of flaws in the leading edge structural subsystem of the NASA space shuttle.
