Recomputation of the Seismic Hazard at the Idaho National Engineering and Environmental Laboratory
- INEEL POC
The probabilistic seismic hazard at five facility areas at the Idaho National Engineering and Environmental Laboratory (INEEL), including TRA, RWMC, PBF, TAN, and NRF has been recomputed using recently developed ground motion attenuation relationships appropriate for extensional tectonic regimes. The INEEL is located adjacent to the extensional Northern Basin and Range Province where the seismic sources significant to the site are located. Ground motions were recomputed using empirical attenuation relationships and site-specific stochastic model-based relationships. The empirical attenuation relationships were adjusted for extensional tectonic regimes as part of the Yucca Mountain Project. Seismic hazard curves and uniform hazard spectra for rock were produced using these updated attenuation relationships. The resulting ground motions are lower than the results of the 1996 INEEL site-wide seismic hazard evaluation. The computed peak horizontal accelerations are given.
