ANS 2.27 – Criteria for Investigations of Nuclear Facility Sites for Seismic Hazard Assessments
ANS 2.27-2020 provides criteria and guidelines for conducting geological, seismological, geophysical, and geotechnical investigations needed to provide information to support the following:
seismic source characterization input to a probabilistic seismic hazard analysis (PSHA);
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;
