e sections of the design are also contained in Chapter 3. DRAFT Rev. 0 - April 1996 14.3-24 c. 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 must 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. 3. Tier 2 Supporting Information The DCD Tier 2 must include all information reviewed by the staff which is relied upon in reaching the staff's safety determination. All requirements for the design must be included in the DCD Tier 2. To the extent that design detail or other information reviewed in the course of inspections or audits is necessary for the staff to reach a safety conclusion, that design detail or other information must be in the DCD Tier 2. It is not sufficient for such information to be on the docket, it must be in the DCD Tier 2. In some cases, the detailed supporting information necessary to perform the inspections, tests, and analyses, or to demonstrate compliance with the acceptance criteria may not be identified by the standard format for safety analysis reports or the SRP, but is required to
