Human-System Integration

Human-system integration research concerns the integration of human capabilities/intelligence into design of complex systems to support safe, efficient operations. The research is mainly directed toward issues related to technologically advanced, computer-based systems and their effects on operating crew performance.

There are many important trends in advanced control room development, including:

  • Increased automation
  • Development of compact, computer-based workstations as the locus of CR operations
  • Development of intelligent operator aids based on expert systems and other artificial intelligence-based technologies for use in tasks such as alarm processing, diagnostics, accident management, plant monitoring, and procedure tracking.

Related to these trends is a tremendous increase in the range of technological approaches to developing human-system interfaces, such as computer-based controls and graphics displays. These trends have significant implications for plant safety in that they will affect the role of operators in the plant, what operators will be required to know about the plant and plant systems, and the ways in which operators interact with such systems. The objective of the human-systems integration research program is to evaluate these issues with respect to their effects on crew performance and reliability, and to investigate how to best integrate operations, testing, and maintenance personnel into advanced systems.

For example, the following subjects are being examined in specific research projects:

  • Working with the Department of Homeland Security to develop standardized displays and controls for the Advanced Spectroscopic Portal, the Human Portable Radiation Detection System, and other systems designed to detect and identify radioactive isotopes.
  • Providing support to the NIST Center for Neutron Research (NCNR) staff with respect to the control room upgrade for the NIST research reactor, including the development of an overall vision for the new control room, human factors engineering plans, and a purchase specification for the new digital Integrated Display and Control System (ICS).
  • Development of the Human Factors Engineering Program Review Model which provides an evaluation framework and acceptance criteria for the design process of advanced human-machine systems.
  • Development of human factors guidelines for the design of advanced control rooms and the organization of the guidelines into an electronic document to improve access to information and to provide additional evaluation and report generation support functions.
  • Evaluation of the effects of advanced alarm system design features (such as processing and display methodologies) on operator performance.
  • Evaluation of the impact of local control station design characteristics on operator and plant reliability.
