Content:
rrosion, erosion, protective coating failure, silting, and biofouling cannot degrade the performance of the safety-related systems supplied by service water. 7. For multi-unit sites with SWS cross-tie capability, the reviewer verifies whether: A. The sharing of SSCs does not significantly impair SWS capability to perform its safety function, including, in an accident in one unit, an orderly shutdown and cool-down of the remaining unit(s). B. Flushing and flow testing provisions from implementation of GL 89-13 are applied to the cross-tie lines. C. Applicants proposing designs with only two SWS pumps per unit address the provisions of GL 91-13 (Reference 10). 8. To address concerns about SWS equipment operability and containment integrity during design-basis accident conditions, the reviewer verifies whether the applicant addresses the following SWS design provisions consistently with GL 96-06 (Reference 11) and to GL 96-06, Supplement 1 (Reference 12): 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 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
