A computer-simulation-based approach has been proposed to estimate fundamental human error probability (HEP) parameters, which are required for Human Reliability Analysis (HRA) as related with Probabilistic Safety Assessment (PSA) for nuclear power plant (NPP). The target HEP parameters are the ones normally represented by time versus reliability correlation (TRC), which is called as "Time versus Cognitive Reliability" (TCR) curves. in the developed simulation system, "human model adjustment factors" were proposed to model the inherent variety and diversity in human cognitive behaviors, which are considered as the primary factors that generate different TRC. Inter-comparisons were also made between the TCR curves obtained from a laboratory experimental data and the ones obtained by the developed simulation system. It turns out that both TRCT curves agree well with each other for most cases. A discussion about the disagreements in the inter-comparison was also made to suggest the further subjects to enhance the performance of the simulation system.
