Additional guidance on the quality group classification of systems and components important to safety for a typical PWR plant designs is given in Appendix C attached to this SRP section. 69 Similarly, additional guidance on the quality group classification of systems and components important to safety for a typical BWR plant is given in Appendix D attached to this SRP section. AppendicesAppendix C and D, in part, identifyies individual system 70 componentsquality group classifications and related references supplemental to the guidance of Regulatory Guide 1.26 for the classification of system components including appropriate interconnecting piping and valves, by quality group and the applicable code and code class.71 Table 3.2.2-1 attached to this SRP section provides a summary of the construction Codes and Standards for components of water-cooled nuclear power plants and is based on the NRC quality group classification system in Regulatory Guide 1.26. Appendix C identifies additional guidance regarding the construction of certain systems and components.72 OnFor some plants this system may be non-safety-related, providing it complies with the 1 requirementsis quality group classified consistent with the positions of Regulatory Guide 73 1.26.
