Risk-informed, performance-based design of seismic isolation systems for nuclear energy facilities (Andrew Whittaker)
Date: Mar 19, 2026 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…

Application of NRC’s Tier 1 and Tier 2 Seismic Evaluation & Deficiency-Based Upgrading Procedures to an Existing Canadian Building
Date: Jan 21, 2026 Abstract Earthquakes are among the most destructive natural disasters, capable of causing severe casualties and significant economic losses. For building owners, assessing and mitigating seismic risks in existing buildings poses both technical and economic challenges. In Canada, there has long been a need for nationwide technical guidelines for seismic evaluation and upgrading. The National Research Council…

John Hart Dam Seismic Upgrade: A Robust Seepage Barrier for Cascadia Megathrust Resilience (Thava Thavaraj)
Date: Oct 8, 2025 Abstract: The John Hart Dam, constructed in the late 1940s on Vancouver Island, required upgrades to address seismic vulnerabilities and ensure resilience against a potential magnitude M9 mega earthquake originating from the nearby Cascadia Subduction Zone. The Middle Earthfill Dam (MED), one of three earthfill structures at the site, was determined to be at risk of…
