ns. 3.2.1-6 Draft Revision 3 – August 2015 1. RG 1.29 provides guidance used to establish the seismic design classification to meet the requirements of GDC 2, 10 CFR Part 100, Appendix A, and 10 CFR Part 50, Appendix S. This guide describes an acceptable method of identifying and classifying those plant features that must be designed to withstand the effects of the SSE (e.g., seismic Category I features). 2. RG 1.151 provides guidance with regard to seismic design provisions and classification of safety-related instrument sensing lines. 3. RG 1.143 provides guidance used to establish the seismic design provisions of radioactive waste management SSCs to meet the requirements of GDC 2 and GDC 60 as they relate to designing these SSCs to withstand earthquakes. The guide identifies several radioactive waste SSCs requiring some level of seismic design consideration. 4. RG 1.189 provides guidance used to establish the design provisions of fire protection SSCs, including seismic design consideration and seismic classification for certain SSCs. These provisions support an overall system design that meets the requirements of GDC 2 as it relates to designing these SSCs to withstand earthquakes. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with GDC 1 and 10 CFR Part 50, Appendix B, requires that SSCs important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. GDC 1 requires, in part, that a QA Program be established and implemented to provide adequate assurance that SSCs important to safety will satisfactorily perform their safety functions. Regulations in 10 CFR Part 50, Appendix B, establish QA program requirements for the design, construction, and operation of SSCs important to safety. The requirements of 10 CFR Part 50,
