S 51.1, 52.1, and ANS 58.14), reference documents such NUREG/CR-5973, “Codes and Standards and Other Guidance Cited in Regulatory Documents”, can support identifying industry standards that can be referenced and justified in an application. Certain additional systems not identified in RG 1.26 have established staff positions regarding quality group classification. These systems, and references establishing their acceptable classifications, are identified in Appendix A. 2. The information supplied in the application identifying application of the quality group classification criteria to fluid systems important to safety is reviewed for completeness, and the quality group classification, ASME BPV Code and code class, and quality assurance criteria of selected individual major component are checked for compliance with the above criteria. Safety functions for each component are not specifically 3.2.2-8 Draft Revision 3 – August 2015 identified in the FSAR classification table. The staff may question the basis for a particular component classification and/or confirm the classification basis during an audit or via an ITAAC to validate that the applicant has an appropriate classification process. The various modes of system operation are to be considered to ensure that the assigned NRC quality groups are acceptable. Completeness of a QA list is beyond scope of RG 1.26 and this SRP. 3. Quality groups and their respective ASME BPV Code class for fluid systems and major pressure-retaining components are to be included in a table. The system description and schematics or P&IDs, if applicable, typically duplicate the quality group or corresponding code class information presented in the table. Where the table does not clearly describe boundaries, the system description and schematics or P&IDs, if applicable, may be reviewed to ensure that the applicant has delineated in detail the system quality group classification boundaries for systems important to safety.
