THIS CHAPTER REVIEWS plant operating and maintenance department requirements associated with in-service coating inspection and covers guidelines for monitoring coating performance in an operating nuclear power plant. Establishment of an in-service coatings surveillance plan permits planning and prioritization of coatings maintenance work to maintain coating integrity and performance in all coating systems, and Service Level I coating systems in particular. It also enables identification and detection of potential problems in coating systems known in advance to be suspect or deficient for some reason and assists in recommendations for follow-up procedures to resolve any significant deficiency relative to coating work. A surveillance plan may also be required to fulfill technical specifications and safety analysis report commitments, if any, for Service Level I coating work.
