eventing missiles generated by tornado winds from causing significant loss of watertight integrity of the fuel storage pool and from contacting fuel within the pool.; 2. Meeting RG 1.27, Positions C.2 and C.3, "Ultimate Heat Sink for Nuclear Power Plants," so that the ultimate heat sink is capable of withstanding the effects of external missiles generated by natural phenomena; 3.5.2-7 Revision 3 - March 2007 3. Meeting RG 1.115, Position C.2, "Protection Against Low Trajectory Turbine Missiles," so that essential systems are protected from low-trajectory turbine missiles by either proper turbine orientation or missile barriers; 4. Meeting regulatory Positions C.1, C.2, and C.3 and the Appendix to RG 1.117, "Tornado Design Classification," so that important safety-related SSCs are protected from the effects of missiles generated by the design basis tornado by missile barriers for individual components, by location of independent redundant systems or components in missile-protected structures, or by underground locations at depth sufficient to protect against missiles; and 5. Identifying all SSCs requiring protection against the effects of externally-generated missiles, including those nonsafety-related SSCs, the failure of which as a result of missiles, may prevent safety-related SSCs from performing their safety-related functions. For those applicants referring to a certified design, the reviewer finds that SSCs outside of the DC scope that may cause external missile generation will not prevent safety-related SSCs from performing intended safety functions. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable.
