these sections to ensure that 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. 2. Section 2 — Definitions No review guidance needed. 3. Section 3 — References In addition to the references listed in IEEE Std 603, HICB reviewers should be familiar with the standards, regulatory guides, branch technical positions (BTPs), and other guidance relevant to the topics under review. Rev. 4 — June 1997 SRP 7.1-C-3 The applicable documents are identified in the discussion of each review topic below. Additional background or detailed information relevant to this review can be found in the references to this section. 4. Section 4 — Safety System Designation Section 4 of IEEE Std 603 requires in part that a specific basis be established for the design of each safety system. 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. For protection systems, the design basis 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 IEEE Std 603 Sections
