n 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. Reviewers should use the Review Checklists in Appendix C to SRP Section 14.3 as an aid in establishing consistent and comprehensive treatment of issues. 3. Ensure that the reactor systems 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 reactor and core cooling systems issues in Tier 1 are treated in a consistent manner among branches. 5. Ensure that inputs from SPSB regarding PRA, including shutdown safety evaluations, and SCSB regarding severe accident analyses are appropriately treated in Tier 1. 6. 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. In particular, 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). 7. Ensure that design features from the resolutions of selected policy and technical issues are adequately addressed in Tier 1, based on safety significance. Ensure that the 14.3.4-5 DRAFT Rev. 0 - April 1996 appropriate Commission guidance, requirements, bases and resolutions for these items are documented clearly in the SER. 8. Ensure that any Tier 2* information is clearly designated in Tier 2, and consider expiration of these items at first full power, if appropriate. The staff's basis for designating the
