Content:
s, associated with one or more radio-navigational 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 that 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. 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 SSCs that are susceptible to impact or fire damage as a result of aircraft crashes. 8. Review Procedures Specific to 10 CFR Part 52 Application Type A. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. The scope and level of detail of review of data parallel that used for a CP review. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on
