TL;DRAbstract

This paper discusses the conceptual framework and the project progress for a benchmarking task defined under the framework of a collaborative agreement between the U.S. Nuclear Regulatory Commission (NRC) and the Ohio State University (OSU). The objective of this task is to develop both policies and methods for inclusion of reliability models for digital systems into the current generation nuclear power plant Probabilistic Risk Assessments (PRAs), thus addressing the need to include the digital system contribution to the overall risk within a plant PRA framework.
