O. Paton Elektric Welding Institute National Academy of scinces of Ukraine popup.description2  1 The methodology for automated space-hour ultrasonic testing of various welded joints made from steel 20, 22K, 08Х18Н10Т, 30ХМА and St3sp5, welded metal structures and steam generators of the VVER-440 reactor has been developed. 2 An ultrasonic examination of the different weld seam No. 76, 77 of the steam generator 1PG of the VVER-440 reactor unit of the power unit No. 1 of the Rivnenska AES was carried out using the method of verifying the detailed methodology of complex diagnostics based on the space-hour method at ultrasonic control. 3 Based on the additional two-criteria diagram of the assessment of the structure, the criteria for the structural value of various welded joints are established, which makes it possible to predict the mechanisms of their structure and the nature of the development of the defect. and in the welded seams of steam generators of the VVER-440 reactor installation, which can be vicorized when lining the reliable and safe operation of welded metal structures and steam generators of AES of Ukraine.
