Whaley,1 Jing Xing2 Ronald L. Boring,1 Stacey M. L. Hendrickson,3 Jeffrey C. Joe,1 Katya L. Le Blanc,1 Stephanie L. Morrow2 1Idaho National Laboratory2U.S. Nuclear Regulatory Commission3Sandia National Laboratories Erasmia Lois and Jing Xing, NRC Project Managers Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Availability Notice Abstract This report documents the results of a literature review to synthesize human cognition research into a technical basis for human reliability analysis. The U.S. Nuclear Regulatory Commission (NRC) organized a team of researchers to review literature in psychology, cognition, behavioral science, and human factors and apply it to human performance in nuclear power plant operations. The project team synthesized the results into a cognitive framework that consists of five macrocognitive functions: (1) detecting and noticing, (2) understanding and sensemaking, (3) decisionmaking, (4) action, and (5) teamwork. For each macrocognitive function, the team identified proximate causes for why the cognitive function may fail, cognitive mechanisms underlying the failures, and factors that influence the cognitive mechanisms and may lead to human performance errors. Moreover, the project team used the information in the literature to infer causal relationships and links between different types of human failures and factors that influence human performance. This report provides a cognitive basis for human performance and a structured framework to assess how human performance may contribute to errors in the context of an evolving event scenario. The information can serve as the technical foundation for the NRC's human reliability analysis methods and human factors engineering guidance.
