Assessment of HRA method predictions against operating crew performance: Part II: Scenario, description, human failure events, overall simulator data, and HRA method predictions
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
This is the second in a series of four papers documenting two large-scale human reliability analysis (HRA) empirical studies – the International HRA Empirical Study and the US HRA Empirical Study. The goal of the two studies was to develop an empirically-based understanding of the performance, strengths, and weaknesses of HRA methods by comparing HRA method predictions against actual operator performance in simulated accident scenarios on nuclear power plant (NPP) simulators. The first paper (Part I), provided background in formation for the studies and an overview of their design and methodology. This paper first briefly describes the scenarios simulated in the studies and the associated human failure events (HFEs) addressed in the HRA analyses. Then, it discusses the overall simulator data followed by observations on the operating crew performance in the scenario simulations. Lastly, it presents some quantitative comparisons of the HRA methods’ predictions with the simulator data.
