epth and surveillance tests to confirm drywell leak tightness, consistent with the bypass fraction used in computing the overall decontamination. 5. 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 early site permit (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. 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 following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. 1. The staff has reviewed the fission product scrubbing function of the pressure suppression pool and finds that the pool will reduce the fission product content of the steam-gas mixture flowing through the pool following accidents that blow down through the suppression pool. The staff estimates that the pool will decontaminate the flow by a factor of ______ for molecular iodine vapor and by a factor of ______ for particulate fission products. No significant decontamination of noble gases and
