[en] The United States Nuclear Regulatory Commission (USNRC) is sponsoring an on-going research program to develop methods of assessing various types of computer-generated displays currently being implemented in nuclear power plant control rooms. The purpose of this report is to present an interactive simulation technique for the evaluation of computer-generated displays. The independent variables for this experiment were transient type (six levels), and display type including the levels of star + control panel, bar + control panel, meter + control panel, pressure-temperature map + control panel, and control panel only. The dependent measures were deviations of parameter values comprising the safety functions at risk, percent of time these parameters were out of tolerance from onset of the transient, and accuracy of the operator path in transient mitigation. The results indicate that an interactive simulation method can be used to evaluate various display types, and that the workstation and computer/simulator is an effective configuration. The implications of these results for display evaluation and design are discussed
