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

Abstract RU 2200317 C2

FIELD: ultrasonic flaw inspection of fuel- element welds. SUBSTANCE: test specimen used for ultrasonic flaw inspection of welds in thin-walled cans of fuel elements provided with plugs has can and plug joined together by means of annular weld. This weld incorporates man-made flaws such as lack of penetration, ball- shaped defect of blister type, and holes over radius and chord. EFFECT: enhanced precision of acoustic check-up and flaw-detection means calibration. 1 dwg
