dards applicability in accordance with criteria and methods contained in the SRP sections corresponding to the review of the particular systems. Safety functions are not typically included in the FSAR classification tables for each component. Therefore, if any quality group 3.2.2-4 Draft Revision 3 – August 2015 classification shown on a system description and schematics or P&IDs, if applicable, is inconsistent with the specific design basis safety function of a fluid system component, the staff should request additional information from the applicant to clarify and resolve the discrepancy and document the resolution in the safety evaluation report.. 1. Electrical and instrument systems that are not pressure-retaining are beyond the scope of RG 1.26 and this SRP section and are reviewed in other SRP sections including SRP Sections 3.10 and 3.11 and in Chapters 7 and 8. 2. The staff determines the adequacy of the inservice inspection programs for the RCPB and for ASME BPV Code Class 2 and 3 components, as part of the primary review responsibilities for SRP Sections 5.2.4 and 6.6. 3. The staff verifies that all items are addressed under the QA program consistent with their importance to safety, as part of the staff’s primary review responsibilities for SRP Section 17.5. The applicant’s QA list referenced in 10 CFR 50.34, “Contents of Applications; Technical Information,” and other SRP sections should identify all SSCs covered by the quality assurance program. The QA list may also reference licensing or design basis documents that specify the specific graded quality requirements and basis for quality group classification, including safety functions. The SSCs included in the FSAR Section 3.2 tables may include items on the QA list that are not pressure-retaining and beyond the scope of SRP Section 3.2.2. In addition, the acceptability of the entire QA list is beyond scope of the SRP Section 3.2.2 review. 4. The regulatory treatment of nonsafety systems (RTNSS)
