e D-RAP program should include risk-significant SSCs as determined by probabilistic, deterministic, or other methods used for design certification to identify and prioritize risk-significant SSCs. The purpose should include ensuring that the detailed facility design remains consistent with the original design bases. The D-RAP program objectives should include that the program provides a reasonable assurance that the plant is designed such that: (1) It is consistent with the assumptions and risk insights for these risk-significant SSCs, (2) the risk-significant SSCs will not degrade to an unacceptable level during their design life, (3) the frequency of transients that challenge these SSCs will be acceptably low, and (4) these SSCs will function reliably when challenged. DRAFT Rev. 0 - April 1996 14.3.10-4 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 regarding ITP and D-RAP descriptions. 3. The reviewer should ensure that appropriate guidance is provided to other branches such that testing and D-RAP issues in Tier 1 are treated in a consistent manner among branches. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided to satisfy the requirements of this Standard Review Plan section, and concludes that Tier 1 is acceptable. The findings should support the following type of conclusive statement to be included in the staff's safety evaluation report: "Based on the staff's review of the material in the (standard design) Tier 1, and a review of the selection methodology and criteria for the development of Tier 1 contained in DCD Tier 2 Section 14.3, the staff concludes that the ITP (or D- RAP) is
