On June 8-9, 2015, PEER hosted the latest in a series of Pacific Rim Forums focusing on the critical issue of resilience of nuclear facilities including nuclear power systems. Ensuring a resilient system that adequately addresses safety, response and mitigation concerns for extreme seismic and tsunami events is essential to achieving a safe facility and realizing the full potential of nuclear power for addressing the energy and environmental needs of a technologically advancing world. The Forum event was hosted in collaboration with the Lawrence Berkeley National Lab, American Association of Structural Mechanics in Reactor Technology (AASMiRT), and Japan Atomic Industrial Forum (JAIF).
