Criteria for Investigations of Nuclear Facility Sites for Seismic Hazard Assessments (reaffirmation of ANSI/ANS-2.27-2020)

This standard provides criteria and guidelines for conducting geological, seismological, geophysical, and geotechnical investigations needed to provide information to support the following:  (1) seismic source characterization input to a probabilistic seismic hazard analysis (PSHA); (2) evaluation of tectonic permanent ground deformation hazard using probabilistic fault displacement hazard analysis for surface-faulting sources and probabilistic tectonic deformation hazard analysis for blind fault sources; (3) site response analysis input to PSHAs; (4) nontectonic, earthquake-induced ground failure hazard; (5) foundation stability.
