ected from tornadoes, tornado and turbine missiles, and floods. This protection meets the positions of RG 1.115, "Protection Against Low-Trajectory Turbine Missiles," Position C.1, and "Tornado Design Classification," Appendix Position 13. B. The applicant has met the requirements of GDC 5, "Sharing of Structures, Systems, and Components," for the ability of shared systems and components important to safety to perform required safety functions. Each unit of the plant has its own emergency diesel generators with EDEFSS not shared between them. C. The applicant has met the requirements of GDC 17, "Electric Power Systems," for the ability of the fuel oil system to meet independence and redundancy criteria. Each EDEFSS is independent and physically separated from the other system serving the redundant diesel generator. A single failure in any one EDEFSS will affect only its diesel generator. This arrangement meets the position of RG1.137 "Diesel Generator Fuel Oil Systems." The applicant has also met the positions of NUREG/CR-0660, "Enhancement Of Onsite Emergency Diesel Generator Reliability." The staff concludes that the EDEFSS design complies with all applicable GDCs, regulatory guide positions cited, NUREG/CR-0660, staff positions, and industry standards and is therefore acceptable. 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. 9.5.4-11 Revision 3 - March 2007 V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an
