Preoperational practices for steam generators and secondary-system components
Technical Report
·
OSTI ID:5251416
PWR operating experience has shown that proper control of steam generator and secondary plant cleanliness during construction will prevent corrosion of critical components, minimize impurity transport to the steam generators, and minimize startup delays. This volume contains the following guidelines which address preoperational practices: Preoperational Flushing, Cleaning, and Layup of PWR Steam/Feedwater/Condensate Systems, Revision 1; and Guidelines to Minimize Contamination of PWR Steam Generators during Plant Construction, Revision 1. The guidelines provide specific recommendations and associated justifications for maintaining steam generator cleanliness during shipment, storage, and installation; and secondary plant cleanliness during construction. Recommendations for preoperational cleaning and flushing of secondary systems are also provided. 1 ref., 9 figs., 2 tabs.
