The EPRI Program S113-1, Evaluation of Secondary System Layup and Cleanup Proctices was established to study ways to minimize the transport of corrosion products into the secondary side PWR steam generators that occurs during plant startups following extended outages. As part of the EPRI Program, Task 200 objective was to identify and categorize the layup and cleanup practices now in use or proposed by utilities for PWR plants. The task study consisted of gathering information by conducting site visits to fourteen representative PWR plants in the USA, Europe and Japan, by conducting a search of the open literature, reviews of related EPRI Programs, and by evaluating the practices in terms of their potential effectiveness. The results show that about 30% of the plants attempt routine layup of secondary systems during outages and about 60% perform some form of system cleanup during the return to power following extended outages.
