review identified above as being reviewed as part of the primary review responsibility of other SRP Sections branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section(s) of the corresponding primary branch.10 II. ACCEPTANCE CRITERIA CMEB EMCB acceptance criteria are based on meeting the relevant requirements of Appendix 11 B to 10 CFR Part 50 as it relates to the quality assurance requirements for the design, fabrication and construction of safety-related structures, systems and components. A coating system to be applied inside a containment is acceptable if it meets the regulatory positions of Regulatory Guide 1.54 and the standards of ANSI N101.2ASTM D3842 and ASTM D3911 (References 4 and 5) . 12 13 Technical Rationale14 The technical rationale for application of the above acceptance criterion to protective coating systems is discussed in the following paragraph. Appendix B to 10 CFR Part 50 requires a quality assurance program which comprises all those planned and systematic actions necessary to provide adequate confidence that a structure, system, or component will perform satisfactorily in service. It is important to prevent the deterioration of protective coatings by one, all, or a combination of the following conditions: ionizing radiation, contamination by radioactive nuclides and subsequent decontamination processes, chemical and water sprays, high-temperature, high-pressure steam, and abrasion or wear. The protective coatings must be resistant to causing generation of combustible gases like hydrogen and methane and gaseous formation of radioactive organic iodides. If the protective coatings deteriorate by flaking, peeling, etc. they may form solid debris which can reach the containment recirculation sump and have a negative impact on the performance of post-accident cooling safety systems. Regulatory Guide 1.54 describes an acceptable method of complying with the quality
