trumentation equipment and measures the program against the requirements listed in Subsection I of this SRP section. Of particular interest is the proper use of test and analytical, or the combination of both, procedures. Equipment that is too complex for reliable mathematical modeling should be tested unless the analytical procedures and corresponding design are conservative. The staff reviews both the test and the analysis methods to ensure that all important modes of response will be excited in tests or considered in analysis. The staff verifies that input motions, in terms of response spectra or time history in all necessary directions, envelop the required input. The staff also reviews the adequacy of equipment supports. If qualification by an experience- based approach is proposed, the staff reviews both the applicant’s justification to use an experience-based approach, and the details of the experience database, including applicable implementation procedures, to ensure structural integrity and functionality of the in-scope mechanical and electrical equipment. Supporting documentation for equipment identified in the experience database should confirm that such equipment remained functional during and after an SSE and the equivalent effect of five postulated occurrences of OBE in combination with other relevant static and dynamic loads. 2. At the operating license (OL) stage or the DC or the COL application stage, the staff reviews the program as described by the applicant in the FSAR. In addition, the staff may review the SQR for documentation of the successful implementation of the qualification program including test and analysis results. The reviewer verifies that the applicant’s list of systems is consistent with the list provided in accordance with SRP Section 3.2.2. If qualification by an experience-based approach is proposed, the reviewer examines both the applicant’s justification to use an experience-based approach, and the details of the
