Location: Marriott Knoxville Downtown (525 Henley Street Knoxville, Tennessee 37902) in the Wiley Room.

Description: Dynamic PRA methodologies explicitly account for the time element in probabilistic system evolution and heavily incorporate plant analysis/simulator tools to model possible dependencies between failure events that may arise from hardware/software/firmware/process/ human interactions. Dynamic PRA methodologies can also quantify the effects of phenomenological variability and model uncertainties on the consequences of upset conditions. They can benefit the PRA modeling of passive systems, including the representation of aging effects and digital instrumentation and control systems.

The workshop's objective is to provide a perspective on dynamic PRA methodologies, the circumstances under which they may be needed, and the existing challenges with their deployment. The use of some of the available software tools will be demonstrated.

Lunch will be available at 11.30 am.
