New NRC Hazard Analysis Earthquake Study Released

submitted by Kay Goss

US NRC study released today on "New Seismic Model Will Refine Hazard Analysis at U.S. Nuclear Plants" and performs studies at many central and eastern U.S. susceptible locations. The Central and Eastern United States Seismic Source Characterization for Nuclear Facilities (CEUS SSC) Project was conducted from April 2008 to December 2011 to develop a new, regional seismic source model for use in conducting and reviewing probabilistic seismic hazard analyses (PSHAs) for nuclear facilities in the CEUS. PSHA is a method for assessing site-specific seismic hazard that includes getting the best estimate of ground motions and a transparent quantitative accounting of uncertainty. The results of PSHA are used in seismic design and in calculating seismic risk.
