Content:
flooding (e.g. adequate drainage, sump pumps, etc.) if these features are safety-related to ensure adequate time to perform a safe shutdown. Only seismically-qualified systems should be assumed to be available to mitigate the effects of the flooding from non-seismic systems. 8. A review of plant structure design drawings to determine if the flood protection of any safety-related structure, such as below-grade groundwater seepage depends on a permanent dewatering system. If so, the dewatering system should be designed as a safety-related system and should meet the single failure criterion requirements. In addition, a review of the accidental release of liquid effluents into the groundwater should be performed in accordance with SRP Section 2.4.13. 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 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 ESP or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. 3.4.1-7 Revision 3 - March 2007 IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the
