TEST-SPECIMEN FOR ULTRASONIC INSPECTION OF FUEL ELEMENTS OF NUCLEAR REACTORS Russian patent published in 2003 - IPC

Abstract RU 2209429 C2

FIELD: nondestructive testing, ultrasonic flaw detection in welds of fuel elements of nuclear reactors. SUBSTANCE: increased accuracy of tuning of ultrasonic flaw detector is achieved thanks to manufacture of test-specimen in the form of stepped bar which material matches material of fuel element. Bar has two tail parts, length of step of bar of larger diameter is equal in size to part of plug entering jacket of fuel element. It has ring imitators of slits, bushings are put on both tail parts of bar. EFFECT: increased accuracy of tuning of ultrasonic flaw detector. 1 dwg
