For reviews of DCs, Operating License (OL) and Construction Permit (CP) applications, the staff checks the applicant’s table identifying pressure vessel components, piping, pumps and valves, and the corresponding component code, code edition, and applicable addenda of each ASME Code, Section III, Class 1, 2, and 3 component for compliance with 10 CFR 50.55a. The ASME Code Class requirements applied for non-RCPB components are based on the acceptable component Quality Group classifications verified under SRP Section 3.2.2. 2.

For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should
