Experiments and Modeling in Support of Nuclear Power Plant Probabilistic Risk Assessment in the USA

<!--HTML-->For the past two decades, the Fire Research Division at the National Institute of Standards and Technology (NIST) has performed fire experiments and numerical modeling to support the transition by the US Nuclear Regulatory Commission to a performance-based, risk informed approach to fire safety. The presentation will briefly describe the various projects, including fire model verification and validation, cable fires, compartment fire dynamics, protective cable coatings, incipient fire detection, high energy arc faults, and uncertainty analysis.
