U.S. NUCLEAR REGULATORY COMMISSION Ma REGULATORY GUll OFFICE OF NUCLEAR REGULATORY RESEARCH REGULATORY GUIDE 1.165 S(Draft was DG-1 032) IDENTIFICATION AND CHARACTERIZATION OF SEISMIC SOURCES AND DETERMINATION OF SAFE SHUTDOWN EARTHQUAKE GROUND MOTION rch 1997 :E A. INTRODUCTION In 10 CFR Part 100, "Reactor Site Criteria," Sec tion 100.23, "Geologic and Seismic Siting Factors," paragraph (c), "Geological, Seismological, and Engi neering Characteristics," requires that the geological, seismological, and engineering characteristics of a site and its environs be investigated in sufficient scope and detail to permit an adequate evaluation of the proposed site, to provide sufficient information to support evalu ations performed to arrive at estimates of the Safe Shut down Earthquake Ground Motion (SSE), and to permit adequate engineering solutions to actual or potential geologic and seismic effects at the proposed site. Data on the vibratory ground motion, tectonic surface de formation, nontectonic deformation, earthquake recur rence rates, fault geometry and slip rates, site founda tion material, and seismically induced floods, water waves, and other siting factors will be obtained by re viewing pertinent literature and carrying out field investigations. . In 10 CFR 100.23, paragraph (d), "Geologic and Seismic Siting Factors," requires that the geologic and seismic siting factors considered for design include a determination of the SSE for the site, the potential for surface tectonic and nontectonic deformations, the de- USNRC REGULATORY GUIDES Regulatory Guides wre Issued to describe and make available to the public such informa lion as methods acceptable to the NRC staff for Implementing specific parts of the Com missions reguldion, techniques used by the staff In aluaftng specific problems orpoe Uated accidents, and data needed by he NRC staff In Its review of applicatiors for per mits aid licenses.
