Revision 6 – August 2016 A review of protection systems by the organization responsible for the review of I&Cs that follows the guidance of IEEE Std 279-1971 should be coordinated with other organizations as appropriate to address the following considerations: • Many of the auxiliary supporting features and other auxiliary features are described in Chapters 4, 5, 6, 8, 9, 10, 12, 15, 18 and 19 of the safety analysis report (SAR). The reviewers from the organization responsible for the review of I&C should coordinate with the reviewers of these SAR sections to ensure 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. The reviewers from the organization responsible for the review of I&C should coordinate with the reviewers of these sections of the SAR to ensure the I&C systems appropriately address these requirements. • I&C systems may impose requirements upon other plant systems and analyses. The reviewers from the organization responsible for the review of I&C 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. The reviewers from the organization responsible for the review of I&Cs 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. 3. DESIGN BASIS Clause 3 of IEEE Std 279-1971 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
