Probabilistic assessment of the seismic hazard for Eeastern United States nuclear power plants

The purpose of the seismic hazard characterization of the Eastern United States project, for the Nuclear Regulatory Commission, was to develop a methodology and data bases to estimate the seismic hazard at all the plant sites east of the Rocky Mountains. A summary of important conclusions reached in this multi year study is presented. The magnitude and role of the uncertainty in the hazard estimates is emphasized in regard to the intended final use of the results. (orig.)
