iewed and accepted under SRP Section 4.4. Typically, the criteria define a departure from nucleate boiling ratio (DNBR) less than 1.30 when NRC-approved CHF correlations are used. B. The reviewer must determine the total number of failed rods used in the radiological evaluation. The number of fuel rod failures due to each failure mechanism addressed in SRP Section 4.2 must be combined. C. The reviewer determines the acceptability of the time-dependent activity releases from both containment leakage and plant cool-down (steaming/release via atmospheric dump valves). Each scenario should be investigated in combination and separately for the most severe release path. 3. 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. 15.4.8-6 Revision 3 - March 2007 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). 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. The staff concludes that the analysis of the rod ejection accidents is acceptable and meets GDC 28 requirements. This conclusion
