The Nuclear Regulatory Commission (NRC) has issued a new guide in its Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques used by the staff in its review of applications for permits and licenses, and data needed by the NRC staff in its review of applications for permits and licenses.
Regulatory Guide 3.73, “Site Evaluations and Design Earthquake Ground Motion for Dry Cask Independent Spent Fuel Storage and Monitored Retrievable Storage Installations,” provides guidance acceptable to the NRC staff for (1) conducting a detailed evaluation of site area geology and foundation stability, (2) conducting investigations to identify and characterize uncertainty in seismic sources in the site region important for the probabilistic seismic hazard analysis; (3) evaluating and characterizing uncertainty in the parameters of seismic sources; (4) conducting a probabilistic seismic hazard analysis for the site; and (5) determining the design earthquake ground motion for the site to satisfy the requirements of NRC's regulations.
