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 review of possible effects of internally-generated missiles (outside containment) included SSCs whose failure could prevent safe shutdown or cause significant uncontrolled release of radioactivity. The staff’s review concluded that the applicant's design bases and criteria for SSCs important to safety necessary to maintain a safe plant shutdown meet the 10 CFR 50, Appendix A, GDC 4 requirements for SSCs to be protected from internally-generated missiles (outside containment), because the applicant: A. Has met guidance recommended in RG 1.115, "Protection Against Low Trajectory Turbine Missiles," Sections C.1 and C.3, as to the identification and protection of SSCs important to safety from the effects of turbine missiles, respectively; B. Has used methods to identify potential sources of internal missiles and demonstrated the adequacy of the protection methods, as reviewed by the staff in this or in previous applications and found acceptable; and C. Has shown that the functions of SSCs important to safety will be protected from internally-generated missiles (outside containment) by individual missile-proof structures, adequate physical separation for redundant systems or the
