action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.21 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The review of the structures, systems and components (SSC) to be protected from 22 externally generated missiles included all safety-related structures, systems, and componentsSSC provided to support the reactor facility. Based on the review of the 23 applicant's proposed design criteria, design bases, and safety classifications for SSC necessary for safe reactor shutdown, the staff concludes that the SSC to be protected from externally generated missiles are in conformance with General Design Criteria 2 and 4. This conclusion is based on the following: The applicant has met the requirements of General Design Criteria 2 and 4 with respect to protection of SSC important to safety against the effects of externally generated missiles by: (1) Meeting Regulatory Position C.2 of Regulatory Guide 1.13, "Spent Fuel Storage Facility Design Basis," by preventing 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 Regulatory Position C.2 and C.3 of Regulatory Guide 1.27, "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) Meeting Regulatory Position C.1 in Regulatory Guide 1.115, "Protection Against Low Trajectory Turbine Missiles," such that essential systems are protected from low-trajectory turbine missiles either by proper turbine orientation or by missile barriers; DRAFT Rev. 3 -
