Abstract
Risk-informed pathways are being developed for the design and licensing of next generation nuclear facilities. This presentation will address one such pathway to implement seismic base isolation, which involves the development of a) isolation-system-specific seismic displacement demand curves from seismic hazard curves, and b) fragility functions for seismic isolation systems. Risk calculations result in a displacement, D50, that forms the basis for the prototype testing of isolators and dampers. Specific topics addressed in the presentation include the derivation of the displacement demand curves and isolation-system fragility functions, and calculations of risk.
