Plant procedures are instructions to guide operators in monitoring, decision making, and controlling nuclear power plants. While plant procedures historically have been paper-based, computer-based procedures (CBPs) are being developed to support procedure use. CBPs have a range of capabilities that may support operators and reduce demands associated with paper procedures. The objective of this study was to establish human factors review guidance for CBP systems based on a technically valid methodology. While the study mainly addressed emergency operating procedures, much of the guidance developed applies to other types of procedures. First, a CBP characterization was developed for describing their key design features including both procedure representation and functionality. Then, the research on CBPs and related areas was reviewed. This information provided the technical basis on which the guidelines for design review were developed. The review guidelines address both the design process and the implementation of CBP systems. For some aspects of CBPs the technical basis was insufficient to develop guidance; these aspects were identified as issues to be addressed in future research.
