1 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Grant # 31310020M0002 Grantee: University of Maryland Title of Grant: Improving Foundational Knowledge of Dependency in Human Reliability Analysis Period of Performance: 9/5/2020-9/24/2023 (FY2020 Notice of Funding Opportunity NOFO)
Executive Summary The objective of this project is to perform application-driven fundamental research to enhance the technical basis of Human Reliability Analysis (HRA) by developing the theoretical and mathematical foundations necessary to more consistently and accurately model HRA dependency. The proposed project will 1) clearly define HRA dependency constructs, 2) develop a mathematical framework for modeling HRA dependency relationships and 3) develop a mathematical framework to quantify dependency using HRA data. The approach will draw on novel data analysis, causal models, and artificial intelligence techniques and will connect those to existing and emerging HRA methods and HRA data used throughout the NRCs regulatory activities. The outcome of the work will be enhanced foundational knowledge which will be directly fill known gaps in the HRA methods used within NRCs risk-informed decision-making capabilities.
