that auxiliary features are appropriately addressed by the review. • The site characteristics, systems (both physical and administrative), and analyses described in the other sections of the SAR may impose requirements on the I&C systems. HICB reviewers should coordinate with the reviewers of these sections to ensure the I&C systems appropriately address these requirements. • I&C systems may impose requirements upon other plant systems and analyses. HICB reviewers should coordinate with the reviewers of the affected systems to ensure that the reviewers are aware of these requirements. • Other plant systems will impose requirements on the I&C systems. HICB reviewers should coordinate with the reviewers of the interfacing systems to ensure that these requirements are considered in the review. The coordination review needed for each I&C system is discussed in SRP Section 7.0. 1. Section 3 — Design Basis Section 3 of ANSI/IEEE Std 279 requires in part that a specific protection system design basis be provided. The design basis should be reviewed to confirm that it has the following characteristics: • Completeness — The design basis should address all system functions necessary to fulfill the system's safety intent. The design basis for protection systems should be shown to address the requirements of 10 CFR 50 Appendix A, General Design Criterion (GDC) 20. Information provided for each design basis item should be sufficient to enable the detailed design of the I&C system to be carried out. All functional requirements for the I&C system and the operational environment for the I&C system should be described. As a minimum, each of the design basis aspects identified in ANSI/IEEE Std 279 Sections 3(1) through (9) should be addressed. • Consistency — The information provided in the design basis should be analyzed to confirm its consistency with the plant safety analysis, including the design basis event analysis of Chapter 15 of the SAR; the mechanical and
