PUBLIC PROTECTION NOTIFICATION The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number. 3.7.1-24 Draft Revision 4 - December 2012 APPENDIX A TO SRP SECTION 3.7.1 SPECIFICATION FOR MINIMUM POWER SPECTRAL DENSITY REQUIREMENT For a RG 1.60 horizontal response spectrum anchored to 1.0 g, the following minimum Power Spectral Density (PSD) requirement should be satisfied. For other peak accelerations, this PSD requirement should be scaled by the square of the peak acceleration. The one-sided PSD is related to the Fourier amplitude ( ) F f of the time history by the equation ......................................................................................(1 ) where TD is the strong motion duration over which ( ) F f is evaluated. This duration TD represents the duration of near maximum and nearly stationary power of an acceleration time history record. Additional guidance on estimation of TD for artificial time history or actual earthquake time history is provided in Appendix B of NUREG/CR-5347. The average one-sided PSD defined by Equation (1) should exceed 80 percent of the target PSD as defined by
