Site Amplification Factors Developed Using SSHAC Guidance

This dataset is associated with a project funded by the Nuclear Regulatory Commission (NRC) to demonstrate the application of the Senior Seismic Hazard Analysis Committee (SSHAC) process to the conduct of site response analysis. The SSHAC process is used to develop a consistent, scalable framework for the estimation and subsequent propagation of epistemic uncertainty in site amplification that can be incorporated into a probabilistic seismic hazard analysis (PSHA). The site response analyses were performed for two study sites using the most current methods and models that are consistent with recent state of practice for nuclear facilities and the SSHAC guidance as documented in NUREG–2213 (NRC, 2018). The two study sites are the Garner Valley downhole array (GVDA) and the Savannah River site (SRS). The data contained here include some basic input parameters for the site response analyses and the resulting site adjustment factors (SAF) that were utilized in the PSHA. Details about the full study and how the site amplification was incorporated in the PSHA can be found in Rodriguez-Marek et al. (2021).
