ngs would not adversely affect the operation DG-1331, Page 6 of post-accident fluid systems. The latter two examples are not covered by the Service Level III definition because the fire protection and station blackout functions are typically nonsafety-related. Rather than citing the Service Level III term in AMP XI.M42, the staff defined the scope of coatings covered by the AMP as internal coatings/linings for in-scope piping, piping components, heat exchangers, and tanks. The use of this terminology: (1) compensates for the gap in the existing Service Level I and III definitions, and (2) establishes that the scope includes only coatings on the internal surfaces of in-scope components. Harmonization with International Standards There are no International Atomic Energy Agency safety standards that directly address the qualification, application, and maintenance of protective coatings in nuclear power plants. The external guidance endorsed in this RG is developed by ASTM International, whose voluntary consensus standards are developed for international use, and have been adopted for use in many countries and by many international corporations. Currently, over 12,000 ASTM International standards are used around the world to improve product quality, enhance health and safety, and strengthen market access and trade. This RG approves, with certain clarifications and limitations, the use of multiple ASTM International standards that describe proper QA, worker qualification, application and maintenance of protective coatings for nuclear power plants. Documents Discussed in Staff Regulatory Guidance This RG endorses, in part, the use of one or more codes or standards developed by external organizations, and other third party guidance documents. These codes, standards and third party guidance documents may contain references to other codes, standards or third party guidance documents (“secondary references”).
