retained. Any sections of information that were deleted should be indicated in the DCD, and should be contained in a separate, external report. Deterministic severe accident and shutdown risk analyses should remain in the DCD, although these may be edited to remove detailed PRA data, in any. c. Qualitative discussions of the PRA analyses that demonstrate why various design features for structures, systems or components are important should be retained in the DCD. A list of risk-significant structures, systems, and components should be provided in the DCD. These analyses should be retained either in one DCD location or the appropriate sections of the DCD discussing the systems of the design. Also, cross references to other documents should be retained in the DCD if they support the information retained in the DCD. d. Cross-references for probabilistic and severe accident analyses in Tier 2 showing where design features from key integrated plant safety analyses were incorporated into the design should be retained in the DCD in the same form as in the SSAR. Specific cross-references to the appropriate sections of Tier 1 and Tier 2 should be retained. e. Information that is currently in the SSAR but does not involve PRA should be retained in the DCD. This includes items such as 10 CFR 50.34(f) items and unresolved and generic safety issues (USIs/GSIs). 4. Designation of Tier 2* Information in the DCD Tier 2* information is that information in Tier 2 that, if considered to be changed by a combined license (COL) applicant or licensee, requires NRC approval prior to the change. The areas designated as Tier 2* by the NRC staff were listed in NUREG-1503 and NUREG-1462, and these areas should be similar for the passive designs. The areas designated as Tier 2* were generally those associated with detailed structural and equipment design; design and analysis methodology for fuel and control rods; and 14.3-13 DRAFT Rev. 0 - April 1996 supporting material for the Instrumentation
