could lead to radiological consequences in excess of the exposure guidelines of 10 CFR Part 100 with a probability of occurrence greater than about 10 per year should be -7 considered in the design of the plant. If the results of the review do not support a finding that the risk due to aircraft activities is acceptably low, then the design basis acceptance criteria outlined in Item II.2 below applies. 2. General Design Criterion (GDC) 4 of 10 CFR Part 50 (Ref. 13) , Appendix A, requires 31 that structures, systems, and components (SSC) important to safety be appropriately 32 protected against the effects of missiles that may result from events and conditions outside the nuclear power unit. GDC 3 of 10 CFR Part 50, Appendix A, requires that SSC important to safety be appropriately protected against the effects of fires. The plant meets the relevant requirements of GDC 3 and GDC 4, and is considered appropriately protected against design basis aircraft impacts (Reference. 610) and fires (Reference. 37) if the SSC important to safety are capable of withstanding the effects of the 33 postulated aircraft impacts and fires without loss of safe shutdown capability, and without causing a release of radioactivity which would exceed 10 CFR Part 100 dose guidelines. The safety-related SSC to be considered with respect to the above acceptance criteria include those described in the Appendix to Regulatory Guide 1.117, "Structures, Systems, and Components of Light-Water-Cooled Reactors to be Protected Against Tornadoes." Other safety-related SSC, which may not be included in Regulatory Guide 1.117, will be considered on a case-by-case basis in accordance with the acceptance criteria of the appropriate branches having primary responsibility for their protection. DRAFT Rev. 3 - April 1996 3.5.1.6-4 Technical Rationale:34 The technical rationale for application of the above acceptance criteria to aircraft hazards is discussed in the following paragraphs. 1. 10 CFR Part 100, §100.10
