核电站主回路系统主要设备的射线透照工艺

Radiographic Process for Main Equipment of Nuclear Power Station Primary System in Radiographic Testing

摘要: 核电站主回路系统是核电站役前/在役检查的主要检测对象，从射线检测透照工艺入手，系统地介绍了核电站主回路系统主要设备蒸汽发生器SG、反应堆压力容器RPV以及稳压器PRZ的透照方式及实施方法，并对各透照中所使用的专用工具架做了介绍。以岭澳核电站3，4号机组役前检查顺利完成的实际经验为依托，为以后役前/在役检查打下基础。

Abstract: Primary system of nuclear power station is the main examination object of radiographic testing in PSI/ISI. Starting with radiography process in radiographic testing, radiography process and implementation of main equipment as steam generator(SG), reactor pressure vessel(RPV) and pressurizer(PRZ) were introduced quite systematic in primary system of nuclear power station. Radiographic special tools used in each exposure were presented also. Based on the successful experience of pre-service inspection in Lingao No. 3 and 4 nuclear power station, foundation is laid for the PSI/ISI later.
