arity with how these issues were resolved on a design-specific basis and their safety significance. 3. Review the DCD for the evolutionary design similar to the current design, specifically the Tier 1 information, for the purpose of using a similar approach, format, and language and for familiarity with the treatment of SSCs, the appropriate level of design detail, and other certification issues. 4. Review the safety analyses for the design, including analyses of design basis accidents, severe accidents, flooding, overpressure protection, containment, core cooling, fire protection, transients, shutdown risk, ATWS, steam generator tube rupture, Unresolved Safety Issues and Generic Safety Issues (USIs/GSIs) and TMI items, probabilistic risk assessments (PRA), regulatory treatment of non-safety systems (RTNSS), or other analyses as specified by the staff. Review cross-references in Section 14.3 of DCD Tier DRAFT Rev. 0 - April 1996 14.3-4 2 showing where key parameters from these analyses are addressed in the Tier 1 information. Review cross-references for PRA and severe accidents in the applicable sections of Tier 2. 5. Review the methodology and criteria for Tier 1 information in DCD Tier 2 Section 14.3. General Review Procedures 1. Perform the preparatory steps listed above and ensure that the applicant's DCD is consistent with Appendix A. 2. Use the subsections to this SRP for your review area and determine the SSCs that are applicable to your review. 3. Review the Tier 1 design descriptions to ensure that the key performance characteristics and safety functions of SSCs are appropriately treated at a level of detail commensurate with their safety significance. 4. Review Tier 1 to ensure that all information is clearly delineated and consistent with the Tier 2 information. If any new items are added to ITAAC, then ensure that they are also added to the applicable sections of Tier 2, including appropriate supporting analyses. Figures and diagrams should be reviewed
