ss 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. 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. Appropriate quality group classification consistent with RG 1.26 ensures that these components will be constructed to quality standards commensurate with the importance of the safety function to be performed. The review of Quality Group A and B (ASME Section III, Class 1 and 2) RCPB components is discussed in Section 5.2.1.1 of the SER. Other Quality Group B components of systems identified in Position C.1.a through C.1.e of RG 1.26 are constructed to ASME Section III, Class 2. Components in systems identified in Position C.2.a through C.2.d of RG 1.26 are
