Development and validation of a heuristic model for evaluation of the team performance of operators in nuclear power plants

► We develop an estimation model for evaluation of the team performance of MCR. ► To build the model, we extract team performance factors through reviewing literatures and identifying behavior markers. ► We validate that the model is adaptable to the advanced MCR of nuclear power plants. ► As a result, we find that the model is a systematic and objective to measure team performance.
