ction 7.1 of safety analysis reports (SARs) should list all I&C and supporting systems that are important to safety and should identify the regulatory requirements applicable to each of these systems. Consequently, SRP Section 7.1 identifies the acceptance criteria and regulatory guidance expected to apply to these systems. SRP Table 7.1 lists the regulatory requirements, acceptance criteria, and guidance relevant to I&C and summarizes their applicability to each of the typical systems. SRP Appendix 7-1.A discusses the regulatory requirements, acceptance criteria, and guidance in more detail and provides review guidance for each. Three Institute of 7.0-3 Draft Revision 7 – August 2015 Electrical and Electronics Engineers (IEEE) standards (Std) play extensive roles in the review of I&C systems important to safety: (1) IEEE Std 279-1971, “Criteria for Protection Systems for Nuclear Power Generating Stations,” (2) IEEE Std 603-1991, “Criteria for Safety Systems for Nuclear Power Generating Stations,” and (3) IEEE Std 7-4.3.2, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations.” Because of their importance and breadth, the acceptance criteria, guidance, and associated review methods in these three standards are discussed separately in SRP Appendices 7.1-B, 7.1-C, and 7-1.D. SRP Sections 7.2 through 7.9 address the I&C systems important to safety that are typically included in a plant design. These sections summarize the review scope and acceptance criteria applicable to each system but reference the appendices of SRP Section 7.1 for the details of requirements, guidance, and review methods. The discussion of review procedures in SRP Sections 7.2 through 7.9 also highlights review topics that have in the past required the most attention by reviewers. For some review topics, branch technical positions (BTPs) have been prepared to resolve technical problems or questions of interpretation that arose during
