Keywords:Level 3 PRA, Global sensitivity analysis, Metamodels, Machine learning

Surrogate models (metamodels) with low calculation cost that approximate input/output behavior of level 3 PRA calculation code WinMACCS were constructed by several machine learning algorithms and the fidelity was evaluated. In addition, applicability to global sensitivity analysis of the constructed metamodels was confirmed.
