Content:
10 CFR Part 50, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Processing Plants," establishes overall quality assurance program requirements for the design, fabrication, construction, and testing of safety-related nuclear power plant structures, systems, and components. Section IX of Appendix B relates to the control of special processes. Coating systems are deemed to fall in this category. The qualification program for coating systems should confirm that the systems used on ESF will not possibly stop or slow down the flow rates of the ESF fluids during a design basis accident. Identified quantities of soluble acids and bases within the containment must not be great enough to cause excessive hydrogen generation or deleterious corrosion. The criteria for coatings to be used in containments are described in Regulatory Guide 1.54, "Quality Assurance Requirements for Protective Coatings Applied to Water-Cooled Nuclear Power Plants." DRAFT Rev. 2 - April 1996 6.1.1-10 This guide describes an acceptable means for meeting the requirements of Appendix B to 10 CFR Part 50 stated above, with regard to protective coatings applied to ferritic steels, aluminum, stainless steel, zinc-coated (galvanized steel) concrete or masonry surfaces of water cooled nuclear power plants.66 Technical Rationale67 The technical rationale for application of the above acceptance criteria to the ESF materials is discussed in the following paragraphs: 1. GDC 1 and 10 CFR 50.55a require that structures, systems, and components be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to be performed. 10 CFR 50.55a also incorporates by reference applicable editions and addenda of the ASME Boiler and Pressure Vessel Code. ESF functions include emergency core cooling, reactivity control, fission product containment, and heat removal to an ultimate heat sink. These functions are provided to establish,
