Evaluation and Comparison of Ultrasonic Testing Standards of Nuclear Forgings for Pressurized Water Nuclear Power Station

Some important provisions of ultrasonic testing for the forgings provided by RCC-M code(2007 edition and FM1061) were introduced, and the sensitivity, recording conditions and acceptance criteria were analyzed and also compared with that of RCC-M code(2000 edition and 2002 addendum). Some precautions were considered. It aims to provide reference for the designer, purchaser and inspector for their properly using the ultrasonic testing standards of forgings for pressurized water nuclear power station.
