Abstract

Abstract

The main pump used in some nuclear plant has safe ends between the main pump and the main pipe. This paper has studied ultrasonic and radiographic testing techniques. RSE-M and ASME standards were analyzed comparatively, and the engineering practice factors were also discussed. It is proved that UT is accurate, continuous and economical for in-service inspection and supervision of the main pump safe ends crack which is the most common and dangerous.
- Main pump,
- Weld of safe end,
- Ultrasonic testing,
- Radiographic testing
