ion 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 - April 1996 3.5.2-6 (4) Meeting Regulatory Positions C.1, 2, and 3 and the appendix to Regulatory Guide 1.117, "Tornado Design Classification," such that SSC important to safety are protected from the effects of missiles generated by the Design Basis Tornado by providing missile barriers for individual components, locating independent redundant systems or components in missile protected structures or by underground locations at a depth sufficient to protect against missiles; and (5) Identifying all SSC requiring protection against the effects of externally generated missiles., including those nonsafety-related SSC whose failure as a result of missiles may prevent safety-related SSC from performing their safety-related functions.24 For those applicants referencing a certified design, the reviewer finds that SSC outside of the design certification scope that may result in external missile generation will not prevent safety-related SSC from performing their intended safety function.25 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.26 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 27 cases in which the applicant proposes an acceptable alternative method for
