ional facilities, where aircraft can "circle" while awaiting clearance to execute an approach to a landing at an airport or to continue along an airway. Holding patterns which are sufficiently distant from the plant need not be considered (See subsection II above). Otherwise, traffic in the holding pattern should be converted into equivalent aircraft passages taking into account the characteristics, including orientation with respect to the plant, of the holding pattern. The information in Item III.2 above should be used in this evaluation. 6. The total aircraft hazard probability at the site equals the sum of the individual probabilities obtained in the preceding steps. 7. The effective plant areas used in the calculations should include the following: a. A shadow area of the plant elevation upon the horizontal plane based on the assumed crash angle for the different kinds of aircraft and failure modes. DRAFT Rev. 3 - April 1996 3.5.1.6-8 b. A skid area around the plant as determined by the characteristics of the aircraft under consideration. Artificial berms or any other manmade and natural barriers should be taken into account in calculating this area. c. The areas of those safety-related SSC which are susceptible to impact or fire damage as a result of aircraft crashes. Requirements and procedures governing issuance of early site permits for approval of proposed sites for nuclear power facilities are specified in 10 CFR Part 52. Applications for such a permit should include a description of the aircraft hazards for the site. For review of this type of application, such reviews should follow the procedures outlined above.50 Aircraft hazards are considered to be site specific. However, for design certification applications the site parameter envelope may include site proximity criteria for aircraft hazards. Where so specified, this site proximity criteria is verified to be consistent with the acceptance criteria contained in subsection II.1. For applicants
