NRC Issues Regulatory Guide Related to Seismic Design

The NRC is issuing Revision 2 to Regulatory Guide (RG), 1.60, ‘‘Design Response Spectra for Seismic Design of Nuclear Power Plants.”  The NRC is issuing this revision without a public comment period because there are only minor modifications with no substantive changes in the staff regulatory positions. The RG describes an approach that the NRC staff considers acceptable for defining response spectra for the seismic design of nuclear power plants.
