摘要：
A summary is presented of a series of investigations into ultrasonic testing (UT) of reactor pressure vessel feedwater nozzles for detection of thermal fatigue cracks. The report includes an assessment of the reliability of contemporary field UT techniques and describes the development and usage of mock-up nozzle that is available to utilities for verification of proposed techniques. The status of ongoing development and the relationship between inspection capability and fitness-for-service determinations are also briefly described.
