AP1000定子冷却水处理方式及化学控制

Treatment and Chemical Control of AP1000 Stator Cooling Water

冷却水的水质对保证发电机组设备的安全运行至关重要,为了确保发电机组设备的安全运行,对发电机内冷水品质的要求越来越高。分析了AP1000核电机组发电机定子冷却水系统化学控制方式,通过对定子冷水系统化学指标的分析,指出了该类机组化学控制存在的不足,提出了有效的水质控制优化方案,对同类核电机组具有重要的借鉴意义。

The quality of cooling water is vital to ensure the safe operation of generating set, therefore posing increasingly high requirement for the cooling water quality. This paper analyzes the chemical control mode for AP1000 nuclear power generator stator cooling water system, points out the chemical control deficiency based on the chemical index analysis, and proposes the effective water quality control optimization scheme, providing significant reference to the similar nuclear power units.
