Abstract

Abstract

The effectiveness and safety of steam generator chemical cleaning process during reactor plant cooling down was validated in the test.Autoclave was used to simulate the process parameters of steam generator chemical cleaning process during reactor plant cooling down.The effectiveness and safety test of chemical cleaning was performed with Russia formula and A3B1 formula.Experimental results showed that A3B1 formula was more effective and safer than Russia formula for steam generator chemical cleaning.Experimental results also showed that chemical cleaning with composition A3B1 can effectively remove the sludge from SG secondary side of Tianwan NPP.
