چکیده
In the first and second stage nuclear program of Department of Atomic Energy (DAE), technologies are matured for Pressurised Heavy Water Reactors (PHWRs) and Sodium-Cooled Fast Breeder Reactors (FBRs). Pre-service-Inspection (PSI), In-Service-Inspection (ISI) and Post-Irradiation-Examination (PIE) procedures are carried out for mechanical components and structures/assemblies of these reactors, conforming to ASME, ASTM and IIW standards. Non-Destructive Evaluation (NDE) of vital components of nuclear reactors is carried out for pressure vessels, heat exchangers, storage tanks, turbines, coolant channels, primary and secondary cooling systems, nuclear Fuel and fuel handling mechanisms etc. Ultrasonic testing (UT) is one of the safest and renowned NDE techniques adopted worldwide for NDE of major components of nuclear reactors. Ultrasonic techniques with Pulse-Echo or pitch-catch

متن کاملMeasurement and Modelling of the Rubber Resilience based on Ultrasonic Non-destructive Testing in Tires
In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...
متن کاملUltrasonic imaging techniques for non-destructive testing of nuclear reactors, cooled by liquid metals: review
In some nuclear reactors the core is cooled by means of liquid metal alloy, for example, lead-bismuth eutectic alloy. For safety and licensing reasons, an imaging method for evaluation of status of the interior of reactor has thus to be developed. There are no any other physical means except ultrasonic, which would enable to inspect inner reactor parts submerged in the opaque hot liquid metal. ...
