ified 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 constructed to Quality Group C standards, ASME Section III, Class 3. Components in systems identified in Position C.3 of RG 1.26 are constructed to Quality Group D standards such as ASME Section VIII and American National Standard Institute (ANSI)/ASME B31.1. 2. The staff concludes that there is reasonable assurance that pressure-retaining components of fluid systems important to safety have been properly classified as Quality Group A, B, C, or D items and meets the requirements of General Design Criterion 1, “Quality Standards and Records.” This conclusion is based on the applicant having defined and applied an appropriate classification process and design process to meet the requirements of GDC 1 by having properly classified these pressure-retaining components important to safety as Quality Group A, B, C, or D in accordance with the positions of RG 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” or an acceptable alternative. The staff further concludes that the identified pressure-retaining components include major components that, in part, provide assurance that the facility can be operated with adequate protection to the health and safety of the public
