The inspection system for mechanical non-destructive of NPPs type VVER steam generator tube sheet inspection.

摘要：

For the purpose of in-service inspection of steam generators tube sheets of NPPS type VVER (440 and 1000) the mechanical inspection system was developed. The system is designated to realize ultrasonic and eddy current inspection of base material and weld joints of tube sheets,eddy current inspection of steam generator tubes by bobbin and rotation probes and TV inspection of inner surface of tube sheets. The system is fitted with plugging module for weld plugging of defective steam generator tubes. In this article are describes the main facilities of system and presented some in-service inspection results.
