A Model of Operator Interaction with Field Procedures: Insights for Computer-Based Procedures

摘要

Paper-based procedures (PBPs) are used to manage human performance in the nuclear power industry bothin the field, and in the main control room. Though PBPs are viewed as a necessary tool to guide operatorsthrough complex tasks, limitations in paper-based systems may increase operator workload and contributeto errors. Plans to upgrade aging plants with digital equipment and wireless technology may present anopportunity to enhance procedures by migrating them to computer-based systems. These computer-basedprocedures (CBPs) have the potential to enhance human performance by integrating plant statusinformation and automating many tasks (e.g., place-keeping). CBPs have been explored for more than 30years for use in the main control room; however their actual deployment in the US nuclear plants is yet tobe realized. Currently, the Idaho National Laboratory and participants from the nuclear industry arecollaborating on a research effort aimed at identifying requirements for CBPs used by field operators. Thispaper describes the first step in that effort: a qualitative study and the development of a Model of ProcedureUsage.
