[2L05] Study on cluster analysis methodology for uncertainty of level 3 PRA models

*Ryohei Ichikawa1 (1. NRA)

Keywords:Level 3 PRA, Uncertainty analysis

The results of the uncertainty analysis of the Level 3 PRA were analyzed by performing a cluster analysis grouped by risk by distance, comparing the input parameters between each cluster and analyzing the differences. Through a combination of these analyses, we examined methods to analyze the characteristics of clusters with significant risk impacts.
