Nuclear Power Plant (NPP) operators complete a variety of tasks to ensure the NPP is running safely andefficiently. However, the levels and types of workload associated with the different task types are not yet fullyunderstood. The present investigation examined workload levels and types for three common NPP Main ControlRoom (MCR) tasks in a controlled experimental environment using a variety of subjective, physiological, andperformance measures of workload. The results suggest that the three task types differ in the levels and types ofworkload. These findings can be used to better understand the types of NPP tasks that induce workload and thetype of workload they induce. The full results of these experiments will be captured in future articles andtechnical reports.
