Development of Design Basis Earthquake Parameters for TMI-2 Independent Spent Fuel Storage Installation at the INEEL

Technical Report ·
OSTI ID:768241
Probabilistically-based Design Basis Earthquake (DBE) ground motion parameters have been developed for the TMI-2 Independent Spent Fuel Storage Installation (ISFSI) located at the Idaho Nuclear Technology and Engineering Center (INTEC), Idaho National Engineering and Environmental Laboratory. The probabilistic seismic hazard at INTEC has been recomputed using ground motion attenuation relationships more appropriate for extensional tectonic regimes. The empirical attenuation relationships used in this analysis were adjusted for extensional tectonic regimes as part of the Yucca Mountain Project. Seismic hazard curves and uniform hazard spectra for rock produced using the revised attenuation relationships result in lower ground motions when compared to the results of the 1996 INEEL site-wide seismic hazard evaluation. The DBE ground motions for rock and soil have been developed to be applicable to the TMI-2 ISFSI and the entire INTEC site by incorporating variations in the rock and soil properties over the INTEC area. The DBE rock and soil ground motions presented in the report are recommended for use in developing final design earthquake parameters. Peer reviewers of this report support this recommendation. Because the Nuclear Regulatory Commission regulations have recently evolved to incorporate probabilistically-based seismic design for independent fuel storage facilities, a deterministic Maximum Credible Earthquake analysis performed for INTEC earlier in this study is also presented in this report.
