Additional guidance on the quality group classification of systems and components important to safety for a typical PWR plant is given in Appendix C attached to this SRP section. 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. Appendices C and D, in part, identify individual system components including appropriate interconnecting piping and valves, by quality group and the applicable code and LOn some plants this system may be non-safety-related, providing it complies with the requirements of Regulatory Guide 1.26. 2Portions of the system that perform a safety-related function. 3Portions of the system to outermost
