摘要
在对蒸汽发生器进水冲洗及水压试验时,进入蒸汽发生器的水质必须满足相应的要求,这就要求对凝结水系统、主给水系统进行有效的冲洗。文章介绍了AP1000核电机组在二回路冲洗过程中的准备工作、冲洗路径、冲洗过程中采用的冲洗方法;同时对二回路联合冲洗时的验收标准和冲洗后的保养进行说明;重点对二回路冲洗过程出现的问题进行了经验反馈,为后续机组的系统冲洗和调试工作具有一定的借鉴意义。
At the time of the water flushing and pressure test for the steam generator, the water quality of the steam generator has to meet corresponding requirements. The condensate water system and the main water supply system have to carry out effective flushing. The paper introduces the preparation, flushing path and flushing methods of Haiyang nuclear power plant in the process of the secondary loop flushing. At the same time, the acceptance criteria and the maintenance after flushing are introduced. The experience feedback is the key to the problem of the second loop flushing process, which has certain reference value for the system flushing and commissioning.
