s could include, but are not limited to, comparisons with operating experience or design of similar SSCs. The details of the required analysis should be specified in either the ITAAC or preferably the FSAR. The ITAAC should not reference the applicable section in the FSAR; however, the FSAR sections may reference the ITAAC. For example, FSAR Chapter 3 contains detailed analysis methods of seismic and environmental qualifications that support detailed design descriptions for SSCs and detailed piping design information that supports additional design material applicable to multiple sections of the design. The third column of the ITAAC table should identify the proposed specific acceptance criteria for the inspections, tests, or analyses described in column 2 that, if met, demonstrate that the applicant has met the design commitments/requirements in column 1. In general, to prevent misinterpretation, the acceptance criteria should be unambiguous, objective, and inspectable. When possible, measurable numeric performance values should be specified in the ITAAC acceptance criteria when failure to meet the stated acceptance criteria would clearly indicate a failure to properly implement the design. The numeric values selected should be those assumed in the safety analyses rather than the design values. Each numbered design commitment is entered into the “Design Commitment” column of the ITAAC table. Each design commitment occupies a single row of the ITAAC table. In the “Design Commitment” column, the first ITAAC is numbered “1” followed by a period. Subsequent ITAAC are numbered consecutively and occupy their own row in the ITAAC table. In the “Inspections, Tests, Analyses” and “Acceptance Criteria” columns, information is entered without numbering if a single entry in these columns is sufficient to address the design commitment. If multiple entries are required in these columns, each entry is numbered using the lower case Roman numeral numbering
