R DRAFT Rev. 2 - April 1996 3.5.1.5-4 P = probability of missiles striking a vulnerable critical area of the plant, SC P = probability of missiles exceeding the energies required to penetrate to vital areas p (e.g., based on wall thickness provided for tornado missiles), or producing secondary missiles which could damage vital equipment, and N = number of missiles generated by the design basis event. P may be assumed to be equal to 1 as a first step in the analysis. If P thus calculated is p T greater than 10 per year, then missile effects on SSC should be estimated by SEBECGB -7 19 on request by SABSPLB . The request should be accompanied by a specified missile 20 description, including missile size, shape, weight, energy, material properties, and trajectory. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license 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 Based upon the nature of activities around the site and the review performed, the staff provides an evaluation in one of the following forms, to be included in the staff's safety evaluation report. 1. The staff concludes that the site location, in conjunction with other considerations (such as plant design, construction, and operation) is acceptable and meets the requirements of 10 CFR Part 100, §100.10. This conclusion is based on the information provided by the applicant and reviewed by the staff which demonstrates that the probability of site proximity missiles adversely
