ANS 2.27-2020 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.

Keywords: advanced light water reactors (ALWR), natural phenomenon, nuclear power plant design, siting, seismic hazards, nuclear facility siting, site evaluation, faults seismic sources
