Content:
omponents 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-, 3.2.2-13 Revision 3 – July 2016 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 and those necessary (1) to prevent or mitigate the consequences of accidents and malfunctions originating within the reactor coolant pressure boundary, (2) to permit shutdown of the reactor and maintain it in a safe shutdown condition, and (3) to contain radioactive materials. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP
