DEVICE FOR WELDING TESTING OF REGULATOR ACTUATORS OF CORE REACTORS

摘要

The invention relates to a device for Schweisznahtpruefung on control organ drives of nuclear reactors. The aim of the invention is to increase the reliability of the control organ drives by the application of non-destructive Werkstoffpruefung on. This is achieved by means of a device whose bearing unit is centered on the main flange of the control element drive and which contains a movably mounted manipulator housing which protrudes into the control element drive until the test, the test can be remote-controlled by the central guide tube inside the manipulator housing annular comprehensive support is equipped with inspection and inspection equipment and at the same time scans the weld seam area. {Nuclear Reactor; Control element drive; Reliability; nondestructive material test; ultrasonic testing; Manipulator}
