nt, location, and requirements of the systems. Reviewers should use the review checklists in Appendix C to SRP Section 14.3 as an aid in establishing consistent and comprehensive treatment of systems. Additionally, Tier 1 should be reviewed for consistency with the initial test program as described in DCD Tier 2 Chapter 14. 4. Ensure that the reactor systems are clearly described in Tier 1, including the key performance characteristics and safety-related functions of SSCs based on their safety significance. 5. Ensure that appropriate ITAAC are specified for those SSCs performing safety-related functions for Tier 1 Reactor Systems in the prescribed format as presented in Appendix A to SRP Section 14.3. 6. Ensure that appropriate ITAAC are specified for verifying elevation differences between the reactor core and storage pools and tanks that provide core cooling for passive plants. 7. Ensure that appropriate ITAAC are specified for verifying design pressures of piping systems that interface with the reactor coolant boundary used to validate intersystem LOCA analyses. 8. Ensure that appropriate guidance is provided to other branches such that reactor and core-cooling-systems issues in Tier 1 are treated in a consistent manner among branches. 9. Ensure that inputs from other branches regarding (a) PRA, including shutdown safety evaluations, and (b) severe accident analyses are appropriately treated in Tier 1. 10. Ensure that appropriate ITAAC are specified for verifying those important input parameters used in transient and accident analyses. 11. Ensure that standard ITAAC entries in Appendix D to SRP Section 14.3 related to reactor systems are included, where appropriate, in the systems of the standard design. The reviewer should ensure consistent application and treatment of the standard ITAAC, and in particular for the basic-configuration ITAAC and the net-positive-suction-head ITAAC (for safety-related pumps). 12. Ensure that design features from the resolutions of
