Ultrasonic Inspection of Steam Generators at CANDU Power Plants
TRUSTIE(tm)* has proven to be a valuable tool for inspecting the unique design configuration of CANDU steam generator (SG) tubes. Ultrasonic inspections with TRUSTIE(tm) offer capabilities that can accurately assess the severity of flaws in SG tubes and monitor their growth. TRUSTIE(tm) consistently provides exceptional results in detection and sizing of flaws such as pits, frets and cracks. The applications of TRUSTIE(tm) system effectively supplement Eddy Current techniques for detailed flaw characterization and verify Eddy Current inspection results. Its high resolution capability and sizing accuracy reduce the need for tube plugging, by permitting lower plugging criteria for flawed tubes than that provided by Eddy Current results. The accurate ultrasonic characterization of flaws supports life management programs for SGs. Recent developments in TRUSTIE(tm) ultrasonic inspection technology continue to produce advanced tooling for SG tube inspection. These developments enhance probe and system performance, and minimize the cost for in-service SG inspections. This paper will provide an update of our expanded technical experience, including the development of ultrasonic probes and advanced data analysis techniques, field applications and the benefits of ultrasonic testing in SG tube inspections. keyworks: Tiny Rotating UltraSonic Tube Inspection Equipment
