我国目前共从俄罗斯引进了2台WWER-1000/428核电机组,每台机组包括4台卧式蒸汽发生器,型号为PGV-1000M型。本文在俄罗斯化学清洗配方的基础上,依据某核电站卧式蒸汽发生器二次侧沉积物的成分分析数据,对俄罗斯化学清洗配方进行了单因素变量条件优化实验。实验参考其他化学清洗方法,优化了实验条件,并考察不同EDTA浓度、柠檬酸浓度、清洗时 At present, China has imported 2 WWER-1000/428 nuclear power units from Russia. Each unit includes 4 horizontal steam generators, and the model number is PGV-1000M. Based on the chemical cleaning formula of Russia and based on the composition analysis data of the secondary sediment of a horizontal steam generator in a nuclear power station, the paper makes an experiment on the optimization of the chemical cleaning formula of Russia by the single variable conditions. Experimental reference to other chemical cleaning methods, optimizing the experimental conditions, and examine different EDTA concentrations, citric acid concentration, when cleaning
