What is a Deterministic Seismic Analysis?
A deterministic analysis is one method for assessing the seismic design basis for the proposed site. To do this, a great deal of research is performed to identify all significant faults within about a 60-mile radius from the site. From this research, a controlling active fault and its magnitude are determined. The analysis then calculates the vibratory ground motion (acceleration) to which the site would be subjected if the fault were to slip and cause an earthquake. The results are then used in the design of the various systems needed for safe storage of the spent fuel. The analysis does not include any consideration for how likely the design earthquake is. It only assesses the potential effects at the site from the largest earthquake sources.
