TEST PROTOTYPE FOR ULTRASONIC CONTROL OF HEAT-GENERATING ELEMENTS OF NUCLEAR REACTORS Russian patent published in 2005 - IPC

Abstract RU 2254570 C1

FIELD: the invention refers to the field of non-destructive control.

SUBSTANCE: the proposed test prototype for ultrasonic control of heat-generating elements of nuclear reactors is fulfilled in the form of graduated rod whose material coincides with the material of the covering of the heat generating element. At that in the zone corresponding to the zone of welded seam of the heat-generating element it has a done up opening with the bottom in the shape of hemisphere. The diameter and the depth of the opening make up one fifth of the thickness of the wall of the covering of the heat-generating element.

EFFECT: the usage of the test prototype allows to increase the accuracy of adjustment of installations for controlling quality of welds of nuclear reactors' heat-generating elements made by electron-beam welding.
