calculations, or comparisons with operating experience or design of similar SSCs. The details of the analysis method should be specified in either the ITAAC or Tier 2 (preferred). The ITAAC should not reference Tier 2, but Tier 2 may reference the appropriate ITAAC. For example, detailed analysis methods of seismic and environmental qualification supporting the general provisions in the Tier 1 Introduction are contained in Chapter 3 of Tier 2 and detailed piping design information supporting additional design material applicable to multiple sections of the design are also contained in Chapter 3. Column 3 - Acceptance Criteria This column contains the specific acceptance criteria for the inspections, tests, or analyses described in Column 2 which, if met, demonstrate that the design commitments in Column 1 have been met. In general, the acceptance criteria should be objective and unambiguous. In some cases, the acceptance criteria may be more general because the detailed supporting information in Tier 2 does not lend itself to concise verification. For example, the acceptance criteria for the design integrity of piping and structures may be that a report "exists" that concludes the design commitments are met. In these cases, Tier 2 provides the detailed supporting information on multiple interdependent parameters that should be provided in order to demonstrate that a satisfactory report exists. Numeric performance values for SSCs are specified as ITAAC acceptance criteria when values consistent with the design commitments are possible, or when failure to meet the stated acceptance criterion would clearly indicate a failure to properly implement the design or meet the safety analysis. 5. Tier 2 Supporting Information The DCD Tier 2 should include all information reviewed by the staff which is relied upon in reaching the staff's safety determination. All requirements for the design should be included in the DCD Tier 2. To the extent that design detail or other
