福清核电站＃1机组二回路水压试验水质要求与处理

Requirement of water quality for hydrostatic test of secondary loop of unit No.1 in Fuqing Nuclear Power Plant and water treatment method

核电站二回路水压试验是对蒸汽发生器二次侧管板的严密性及相关系统耐压性的验证,水压试验对水温和水质有严格的要求。介绍了福清核电站#1机组二回路水压试验内容及试验用水的要求,探讨了水质调节措施,提出了水压试验用水的制备流程,按照该流程制备的试验上水完全满足水压试验要求。

The target of hydrostatic test of nuclear power plant secondary loop is to verify the tightness of secondary side tube sheet of the steam generator and the pressure resistance of related system. The quality and temperature of the water used in hydrostatic test must satisfy strict requirements. The hydrostatic test items of secondary loop of unit No. 1 in Fuqing Nuclear Power Plant and the requirements of the test-used water were introduced. The water quality adjustment measures were discussed.The test-used water preparing process was proposed,and the water prepared by above process can satisfy the requirement of the hydrostatic test fully.
