Use of ultrasonic phased array technique for non-destructive testing of the HRK socket at the VVER 440 reactor
 Nováček, Jan ; Kusmič, David (referee) ; Juliš, Martin (advisor)
The bachelor's thesis describes the design of a test system for non-destructive ultrasonic inspection of the HRK on the nuclear reactor VVER 440. Using the designed test system, the basic material interface of the HRK 22K steel shell with the weld on ZIO-8 was verified by the advanced ultrasonic Phased array method. The functionality of the designed test system consisting of the TOPAZ 32 device, the 5L64-A32 probe and the STIX manipulator was tested on three standards with variously large artificial defects. The sensitivity of the test system was set using an artificial defect in the form of a groove 0.7 mm high based on simulations in CIVA 2020 software. The functionality and sufficient sensitivity of the system with a deviation of ± 1 mm for the height of the indication and ± 5 mm for the length of the indication were confirmed by performing experimental measurements on standards.
