Seismic Source Characterization in Siting New Nuclear Power Plants in the Central and Eastern United States

Abstract eng:
The U.S. Nuclear Regulatory Commission (NRC) is currently reviewing several new reactor applications and is expected to receive more applications in the near future. Most of the proposed new reactor sites are located in the central and eastern United States (CEUS). In contrast to the western United States (WUS), the CEUS is less active in earthquake activity and can be considered as a low to moderate seismic area. Lack of surface expression of active faults and strong seismic recordings in the CEUS make seismic siting more difficult. Probabilistic seismic hazard analysis (PSHA) provides a tool to estimate seismic hazard for the CEUS because it is capable of incorporating uncertainties. The NRC endorsed the PSHA method and some PSHA models in Regulatory Guide
