dures. Equipment which is too complex for reliable mathematical modeling should be tested unless the analytical procedures and corresponding design are convincingly conservative. Both the test and the analysis methods are reviewed for assurance that all important modes of response will be excited in tests or considered in analysis. Proper consideration of input motions so as to envelopeenvelop the required input, whether in terms of response spectra or time 68 history in all necessary directions is verified. The use and treatment of supports is also reviewed. 2. At the OL stage, the staff reviews the program again as described by the applicant in the FSAR. In addition, the SQR may be reviewed 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. To confirm the extent to which the equipment meets the requirements of subsection II, the staff audits the equipment qualification and central files and conducts a plant site review. The staff may require that the Seismic Qualification Report (SQR)SQR be 69 submitted to the staff six weeks prior to the plant site visit. If the staff has reviewed an applicant's qualification file for a previous application, they may elect not to require the applicant to submit the SQR, but instead elect only to audit the equipment qualification and central files. The review of the SQR, if applicable, and the audit of the applicant's equipment qualification and central files will include the following: a. For each system the reviewer should verify that summary data sheets are available for all components of these systems and perform a detailed review of these data sheets for selected components. b. The reviewer will audit the central files to verify that the referenced qualification documentation and test reports are available, and perform a detailed
