核压力容器是核电站关键设备之一。为了确保核电站的可靠性、安全性,必须对核压力容器实行严格质量监督,包括制造阶段的例行检查和操作期间的在役检查。本文评述和分析了各种无损检测方法的应用及核压力容器在役检查装置的发展。指出了在役检查对核压力容器设计的要求。
Nuclear pressure vessel is one of the key equipment of nuclear power plant. In order to ensure the reliability and safety of nuclear power plants, nuclear pressure vessels must be subjected to strict quality supervision, including routine inspection at the manufacturing stage and in-service inspection during operation. This paper reviews and analyzes the application of various nondestructive testing methods and the development of in-service inspection equipment for nuclear pressure vessels. The requirements of in-service inspection on nuclear pressure vessel design are pointed out.
