对秦山核电站蒸汽发生器(SG)二次侧在停堆、换料期间的化学清洗工艺进行了工程验证。研究了在室温条件下以EDTA为主的化学清洗组分、配方和清洗时间对SG淤渣成分Fe_3O_4的溶解效率的影响;评定了SG主要材料在化学清洗过程中的抗蚀性;确定了清洗剂允许残余量;制定了适用于秦山核电站停堆、换料期间的化学清洗、漂洗、钝化工艺。工程验
The Qinshan nuclear power station steam generator (SG) secondary side in the shutdown, the chemical cleaning process during the refueling project was verified. The effects of chemical cleaning components, formula and cleaning time on the dissolution efficiency of Fe3O4 SG slag were studied under room temperature. The corrosion resistance of SG main materials during chemical cleaning was evaluated. Agent allowed residual; developed for Qinshan nuclear power plant shutdown, refueling chemical cleaning, rinsing, passivation process. Engineering experience
