Content:
o meet the relevant requirements of the NRC’s regulations identified above are contained in SRP Section 7.1, SRP Table 7-1, and SRP Appendix 7.1-A which list standards, regulatory guides, and branch technical positions (BTPs). 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’s regulations. 1. SRP Appendix 7.1-C provides SRP acceptance criteria for safety system compliance with 10 CFR 50.55a(h). 2. SRP Appendix 7.1-B provides SRP acceptance criteria for protection system compliance with 10 CFR 50.55a(h). 3. SRP Appendix 7.1-D provides SRP acceptance criteria for digital I&C compliance with IEEE Std 7-4.3.2-2003, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations,” as endorsed by Regulatory Guide 1.152, Revision 2, “Criteria for Digital Computers in Safety Systems of Nuclear Power Plants.” III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. Typical reasons for such a non-uniform emphasis are the introduction of new design features or the utilization in the design of features previously reviewed and found acceptable. 7.6-5 Revision 5 - March 2007 These review procedures are based on the identified SRP acceptance criteria. For deviations from these specific acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives to the SRP criteria provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. SRP Section 7.1 describes the general procedures to be followed in reviewing
