Ultrasonic Waveguide Transducer for Under-Sodium Defect Detection and Component Recognition

摘要

A USV test facility was constructed for evaluation and validation of UWT technology. Prototypes of UWTs (12 and 18 in. lengths) were developed and demonstrated successfully in liquid sodium at temperature up to 315℃. The technology has demonstrated a real-time, in-sodium defect detection capability with detection resolutions of 0.5 mm in both width and depth. We also demonstrated the UWT-USV system is capable of recognizing components with 3D geometries, such as rods, cubes, and sphere and potentially locating losing parts.
