ied in conjunction with the basic configuration check of the system. The key dimensions of the RPV system and the acceptable variations of the key dimensions should be provided in the certified design description. Alternatively, acceptable variations and the bases for them should be provided in Tier 2. For component qualification, tests, analyses, or a combination of tests and analyses should be performed for seismic Category I mechanical and electrical equipment (including connected instrumentation and controls) to demonstrate that the as-built equipment and associated anchorages are qualified to withstand design basis dynamic loads without loss of safety function. These test and analyses should be performed as a part of ITAAC to verify the basic configuration of the system in which the equipment is located. See Section 14.3.3 for additional information. III. REVIEW PROCEDURES 1. Follow the general procedures for review of Tier 1 contained in the Review Procedures section of SRP Section 14.3. Ensure that the DCD is consistent with Appendix A to SRP Section 14.3. Review responsibilities may be consistent with those in Appendix B to SRP Section 14.3. 2. Ensure that all Tier 1 information is consistent with Tier 2 information. Figures and diagrams should be reviewed to ensure that they accurately depict the functional arrangement and requirements of the systems, including definitions, general provisions, key dimensions, and legends for figures. Reviewers should use the building structures, fluid systems and electrical systems checklists in Appendix C to SRP Section 14.3 as an aid in establishing consistent and comprehensive treatment of issues. 3. Ensure that the building structures and major components are clearly described in Tier 1, including the key performance characteristics and safety functions of SSCs based on their safety significance. 4. The reviewer should ensure that appropriate guidance is provided to other branches such that structural engineering issues
