quest from the primary reviewer, the coordinating reviewers provide input for the areas of review in Subsection I of this SRP section. The primary reviewer uses such input as required to complete this review procedure. In view of the various designs, the procedures are for a typical CWS designed entirely as a safety-related system. Any variance of the review procedures to take account of a proposed unique design ensures that the system meets the criteria of Subsection II of this SRP section. The review procedures for a safety-related CWS are listed below. Additionally, for a nonsafety-related CWS, the reviewer should use review procedures listed in Table III.1, “Review Procedures for Nonsafety-Related SSCs of the Chilled Water System”. 1. Programmatic Requirements ─ In accordance with the guidance in NUREG-0800 “Introduction,” Part 2 as applied to this SRP Section, the staff will review the programs proposed by the applicant to satisfy the following programmatic requirements. If any of the proposed programs satisfies the acceptance criteria described in Subsection II, it can be used to augment or replace some of the review procedures. It should be noted that the wording of “to augment or replace” applies to nonsafety-related risk-significant SSCs, but “to replace” applies to nonsafety-related nonrisk-significant SSCs according to the “graded approach” discussion in NUREG-0800 “Introduction,” Part 2. Commission regulations and policy mandate programs applicable to SSCs that include: • Maintenance Rule, SRP Section 17.6 (SRP Section 13.4, Sample final safety analysis report (FSAR) Table 13.4-x, Item 17), and RG 1.160, “Monitoring the Effectiveness of Maintenance at Nuclear Power Plants”. • Quality Assurance Program, SRP Sections 17.3, “Quality Assurance Program Description,” and 17.5, “Quality Assurance Program Description - Design Certification, Early Site Permit and New License Applicants,” (SRP Section 13.4, Table 13.4,
