Content:
area which would cause earthquakes to be centered there. 2. The response spectrum proposed for the safe shutdown earthquake is the appropriate free-field response spectrum in conformance with Appendix A to 10 CFR Part 100. The new information reviewed for the proposed nuclear power plant is discussed in Safety Evaluation Report Section 2.5.2. The staff concludes that the site is acceptable from a seismologic stand- point and meets the requirements of (1) 10 CFR Part 50, Appendix A (General Design Criterion 2), (2) 10 CFR Part 100, and (3) 10 CFR.Part 100, Appendix A. This conclusion is based on the following: 1. The applicant has met the requirements of: a. 10 CFR Part 50, Appendix A (General Design Criterion 2) with respect to protection against natural phenomena such as faulting. b. 10 CFR Part 100 (Reactor Site Criteria) with respect to the identification of geologic and seismic information used in determining the suitability of the site. - 2.5.2-10 Rev. 2 - August 1989 c. 10 CFR Part 100, Appendix A (Seismic and Geologic Siting Criteria for Nuclear Power Plants) with respect to obtaining the geologic and seismic information necessary to determine (1) site suitability and (2) the appropriate design of the plant. Guidance for complying with this regulation is con- tained in Regulatory Guide 1.132, "Site Investigations for Foundations of Nuclear Power Plants," Regulatory Guide 4.7, "General Site Suitability for Nuclear Power Stations," and Regulatory Guide 1.60, "Design Response Spectra for Seismic Design of Nuclear Power Plants." V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant/licensee proposes an acceptable alternative method for complying with specific portions of the Commission's regulations, the methods described herein will be used by the staff in its evaluation of conformance with Commission regulations.
