d by the primary review organization for whether the applicant commits to address the potential for water hammer in the auxiliary CWSs and provides means for prevention or avoidance (e.g., venting and filling capability) and operating procedures for avoidance of water hammer. Guidance for water hammer prevention and mitigation is in NUREG-0927 (Reference 12). 8. To address concerns about CWS equipment operability and containment integrity during design-basis accident conditions, the primary review organization verifies whether the applicant addresses the following CWS design provisions consistently with GL 96-06 and GL 96-06, Supplement 1: A. Capability of cooling water systems serving the containment air coolers to withstand the hydrodynamic effects of water hammer and to satisfy system design and operability requirements. B. Capability of cooling water systems serving the containment air coolers to meet heat removal assumptions for design-basis accident scenarios, even during two-phase flow conditions. C. Capability of isolated water-filled sections of piping in containment to withstand thermally-induced overpressurization. 9. For review of a DC application, the reviewers 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 be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report).
