- Abstract
- The report presents a review of the seismic probabilistic risk assessment and seismic margins studies for nuclear power plants in the United States. The techniques employed in these studies are briefly described. A few comments on the evaluation of the fragility of structures and equipment are discussed. Seismic PRA is a systematic process to evaluate the safety of nuclear power plants. In the process, it integrates all the elements such as seismic hazard, component fragility and plant system. Thus, it provides the overall view of the safety of an entire plant under a seismic event. The major tasks of a seismic PRA such as the evaluation of hazard curves, component fragilities. The concept and technique embodied in seismic PRA for nuclear power plants can be applied to other types of engineering facilities.
