摘要
根据第三代非能动压水堆(CAP1400)水堆核电蒸汽发生器制造过程中积累的经验并结合其他压水堆型核电蒸汽发生器的制造经验,介绍了CAP1400蒸汽发生器的结构特点,并分别对制造过程中的一些关键制造技术,如管板一次侧镍基堆焊、管板深孔钻、内套筒的装配、管束穿管、液压胀管和水室封头焊接等进行详细的阐述,为后续压水堆型核电蒸汽发生器的制造提供经验参考。
According to the manufacture experience of C, en Ⅲ passive pressurized water reactor （CAP1400） steam generator and combining with the manufacture experience of other pressurized water reactor steam generator,the structure characteristic of CAP1400 steam generator was introduced, some key technology during CAP1400 steam generator manufacture in detail, such as tubesheet primary side nickel- based alloy cladding, tubesheet deep drilling, installation of the bundle wrapper, tubeset insertion assembly, tube hydraulic expansion, channel head welding and so on were also introduced. It provides some reference for manufacturing the PWR steam generator.
