ned in 10 CFR 50.2, “Definitions,” means that information which defines the specific functions to be performed by SSCs and the specific values or ranges of values chosen for controlling parameters as reference bounds by design. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 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
