e staff may elect to audit available design documents such as design specifications, system description and schematics or P&IDs (if applicable), QA lists, and procurement documents associated with the quality group classification of risk-significant systems and mechanical components. An audit should be scheduled based on the availability of design documents and should occur prior to the DC or COL issuance. The staff review may include an assessment of the degree of completeness of design information supporting classifications and how quality group classification and/or code class identified in the licensing basis are translated into design documents. The audit may also be used to support resolution of quality group open items identified during the review of the application. Depending on the audit plan, the scope may be limited to a review of the design classification process and a sampling of risk-significant systems and mechanical components to validate that the applicant has an appropriate classification process in place. IV. EVALUATION FINDINGS The reviewer determines that the applicant has provided sufficient information and, on the basis of the review and audit (if applicable), that the information provided supports conclusions of the following type, which will be included in the staff’s safety evaluation report (SER). The reviewer also states the bases for those conclusions. 3.2.2-12 Draft Revision 3 – August 2015 1. The application includes a classification process and specific classification criteria consistent with regulatory guidance in RG 1.26 or an acceptable alternative. Pressure-retaining components of fluid systems important to safety and their supports such as pressure vessels, heat exchangers, storage tanks, pumps, piping and valves have been classified Quality Group A, B, C, or D and have been identified in an acceptable manner in Table 3.X.X and on system piping and instrumentation diagrams in the SAR.
