Abstract

Many of the twelve review elements contained in the NRC’s Human Factors Engineering Program Review Model, NUREG-0711, Rev. 3 (NRC, 2012) highlight the importance of workload (WL), situation awareness (SA) and teamwork (TW). The primary purpose of this NUREG/CR is to enhance NRC staff knowledge of the human performance metrics used to measure WL, SA, and TW, and, to provide a tool for evaluating the use of such metrics in applications (e.g., design certification) and proposed license amendments. This report summarizes the most widely used definitions and theories of each of the three constructs (i.e., WL, SA and TW) along with discussing factors that contribute to each. In addition, it describes the psychometric criteria used to evaluate metrics and specifically discusses the measurement and associated metrics of WL, SA and TW. This report also introduces a database of human performance metrics and a tool to assist NRC technical staff in evaluating their use in license applications and proposed amendments. The tool is available on the CD "Workload, Situation Awareness and Teamwork Generic Metrics Catalog (GMC) and Decision Making Wizard (DMW)" located in the back of this report. A user guide to instruct and train NRC technical staff (reviewers) on the organization, capabilities, and applications of the tool can be found in an appendix to this report. For those who are unfamiliar with the NRC’s Human Factors Engineering Program Review Model, an additional appendix includes a review of the NUREG-0711 general activities with an emphasis on the role that WL, SA, and TW measurement plays in the process.
