Development of ultrasonic glancing angle imaging methodology for detection of subassembly protrusion in fast breeder reactors
G Chaitanya, A Kumar - Nuclear Engineering and Design, 2017 - Elsevier
The paper presents an ultrasonic glancing angle imaging based methodology developed for
detection of protrusion and mapping of subassembly (SA) heads in a pool type liquid metal
cooled fast breeder reactor. In the developed methodology, mapping of SA heads is
performed by a single sweep of a transducer inclined at an oblique angle close to the
horizontal plane. A large number of SAs is covered simultaneously due to divergence of the
ultrasonic beam. A significant increase in the acoustic amplitude corresponding to the …
