From such analyses, preventative measures can then be taken to reduce human errors within a system and therefore lead to improvements in the overall level of safety.
Due to this characteristic, the technique is thus not considered to be suitable for use in certain fields such as comparative design work or sensitivity analysis.
Furthermore, its lack of Human Error Probability (HEP) as an output is a marked difference of the method compared to first generation HRA methodologies.
ATHEANA is a post-incident Human Reliability Assessment (HRA) methodology developed by the US Nuclear Regulatory Commission in 2000.
It was developed in the hope that certain types of human behaviour in nuclear plants and industries, which use similar processes, could be represented in a way in which they could be more easily understood.
