Combining Modal Responses and Spatial Components in Seismic Response Analysis

The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 3 to Regulatory Guide (RG) 1.92, "Combining Modal Responses and Spatial Components in Seismic Response Analysis" as an administratively changed guide in which there are minor corrections with no substantive changes in the Staff Regulatory Guidance. This guide describes a method that the NRC staff considers acceptable for combining modal responses and spatial components in seismic response analysis of nuclear power plant structures, systems, and components that are important to safety.
