Evaluation of secondary-system layup and cleanup practices and processes. Final report. [PWR]

Technical Report ·
OSTI ID:6026815
The study of PWR secondary system layup and cleanup practices was undertaken to evaluate current and proposed methods of corrosion product control associated with extended plant outages. The overall goal was to evaluate means for significantly minimizing the steam generator sludge burden. The study included a field survey of 14 representative PWR plants, an extensive literature search and an evaluation of corrosion product transport data. Recommendations for layup and cleanup system processes were derived from these practices and related information. Estimates of the potential benefits to be expected in the control of corrosion products by controlled layup environments during extended outages and by cleanup following such outages are provided. Cleanup during all, or most, phases of operation is indicated as being most beneficial. Layup and cleanup system process design information is also provided.
