A full range of control method for water quality is employed in the practices of secondary loop water control and management at Ningde nuclear plant unit 1 ,namely equipment maintenance and washing during commissioning ,chemical control during outage ,complete rinsing and cleaning of the secondary loop in the pro-cess of start ,and water regulation and control during operation .These have obtained significant performance . Water quality analyses have shown that the secondary loop and steam generator have good water quality ,result-ing in reduced equipment corrosion to a larger extent .
