Content:
��Quality Assurance Requirements for Protective Coatings Applied to Water-Cooled Nuclear Power Plants,” (Ref. 8) to provide an acceptable method for complying with NRC QA requirements for protective coatings applied to ferritic steels, stainless steel, zinc-coated (galvanized) steel, concrete, or masonry surfaces of water-cooled NPPs. Protective coatings that met these guidelines would presumably not degrade over the design life of the plant. However, operating history has shown that undesirable degradation, detachment, and other types of failures of coatings have occurred. These failures are described in Generic Letter (GL) 98-04, “Potential for Degradation of the Emergency Core Cooling System and the Containment Spray System after a Loss-of-Coolant Accident because of Construction and Protective Coating Deficiencies and Foreign Material in Containment” (Ref. 9). If protective coatings detach from a substrate, they can be transported to the intake structure of emergency core cooling systems (ECCS) and can damage the ECCS making them unable to provide cooling as required by GDCs 34, 35, and 36, or satisfy the requirement in 10 CFR 50.46(b)(5). Rev. 0 of RG 1.54 endorses, with some conditions, American National Standards Institute (ANSI) Standard N101.4-1972, “Quality Assurance for Protective Coatings Applied to Nuclear Facilities,” (Ref. 10) and provided a secondary indorsement of the guidance provided in ANSI N101.2- 1972, “Protective Coatings (Paints) for Light-Water Nuclear Reactor Containment Facilities” (Ref. 11). ANSI formally withdrew ANSI N101.4-1972 and ANSI N101.2-1972 in 1988 and transferred the responsibility for updating, rewriting, and issuing appropriate replacement standards to the ASTM International, specifically ASTM International Committee D-33 on Protective Coating and Lining Work for Power Generation Facilities. The ASTM International developed standards to replace ANSI N101.4-1972 and ANSI N101.2-1972. The NRC issued Rev. 1 of RG
