Content:
aphical characteristics of the site and the surrounding area are acceptable and meet the requirements of 10 CFR 100.10(c) [for stationary power reactor site applications before January 10, 1997] or 10 CFR 100.20(c) and 10 CFR 100.21(d) [for stationary power reactor site applications on or after January 10, 1997], with respect to determining the acceptability of the site. The staff finds that the applicant has considered the appropriate site phenomena in establishing the design bases for SSCs important to safety. Specifically, the staff has generally accepted the methodologies used to determine the meteorological, air quality, and topographic characteristics reflected in these design bases, as documented in safety evaluation reports for previous licensing actions. Because the applicant has correctly implemented these methodologies, as described above, the staff has determined that the use of these methodologies results in design basis containing margin sufficient for the limited accuracy, quantity, and period of time in which the data have been accumulated. The staff concludes that the identified design bases meet the requirement of 10 CFR Part 50, Appendix A, General Design Criterion 2, “Design Bases for Protection Against Natural Phenomena,” with respect to establishing the design basis for SSCs important to safety. 2. Early Site Permit Reviews The following statements should be preceded by a summary of the site characteristics and design parameters to be included in any ESP that might be issued for the ESP site: As set forth above, the applicant has presented and substantiated information on local meteorological, air quality, and topographic characteristics of importance to the safe design and operation of a nuclear power plant or plants falling within the applicant’s Plant Parameter Envelope (PPE) that might be constructed on the proposed site. The staff has reviewed the information provided and, for the reasons given, concludes that the applicant’s
