I t I APPENDIX F PROCEDURE TO DETERMINE THE SAFE SHUTDOWN EARTHQUAKE GROUND MOTION F.1 INTRODUCTION This appendix elaborates on Step 4 of Regulatory Position 4 of this guide, which describes an acceptable procedure to determine the Safe Shutdown Earthquake Ground Motion (SSE). The SSE is defined in terms of the horizontal and vertical free-field ground motion re sponse spectra at the free ground surface. It is devel oped with consideration of local site effects and site seismic wave transmission effects. The SSE response
