Biography

Ryan Meyer has been with PNNL since 2010. He’s currently a nuclear engineer and leads the Mechanical Design team within the Reactor Materials and Mechanical Design group in the Nuclear Sciences Division of the Energy and Environment Directorate. Following his PhD, Meyer served as a lecturer with the Electrical Engineering Department faculty at Prince of Songkla University, in Hatyai, Songkla province of Thailand. Since joining PNNL, Meyer’s primary technical focus has been in the areas of nondestructive examination (NDE), NDE reliability, condition monitoring, and prognostics of passive components (e.g., pipes, vessels, tanks, etc.) in nuclear power related facilities, including light water reactors, advanced reactors, and facilities for spent nuclear fuel storage. These efforts include the investigation of ultrasonic/acoustic, electromagnetic, and optical techniques for detection and characterization of degradation phenomena in pressure boundary and in-vessel components, as well as the investigation of techniques to characterize degradation in dry storage cask systems.
