Human factors engineering in nuclear power plants revealed significant control room deficiencies. A study of five plants identified major and minor issues impacting maintenance personnel, highlighting areas for improvement.

Area of Science:

  • Human Factors Engineering
  • Nuclear Power Plant Operations
  • Systems Engineering

Background:

  • Growing awareness of human factors engineering deficiencies in power plant control rooms emerged in the mid-1970s.
  • The Electric Power Research Institute (EPRI) contracted Lockheed Corporation to assess human factors in control rooms and simulators.
  • Previous research identified operational problems and solutions, indicating power plants were not optimized for maintenance needs.

Purpose of the Study:

  • To investigate human factors aspects of power plant maintainability.
  • To identify and overview maintainability problems and issues in nuclear power plants.
  • To build upon prior EPRI-funded research on control room human factors.

Main Methods:

  • Review of human factors engineering in five representative operational nuclear power plant control rooms.

Related Experiment Videos

  • Examination of associated simulators.
  • Analysis of operational problems and maintenance personnel needs.

    • Main Results:

    • Identification of a range of major and minor human factors deficiencies in control rooms and simulators.
    • Unforeseen dimensions of these deficiencies became apparent in the post-Three Mile Island accident context.
    • Evidence suggested significant shortcomings in meeting the needs of maintenance personnel.

    Conclusions:

    • Nuclear power plant control rooms and maintenance areas present substantial human factors challenges.
    • Addressing these human factors issues is critical for operational safety and efficiency.
    • Further investigation into power plant maintainability is warranted based on identified deficiencies.
