Uncertainty Quantification for External Events Analysis of LWRS/RISMC Project
- Idaho National Laboratory, P.O. Box 1625, Idaho Falls, ID, 83415-3860 (United States)
In the framework of the US-DOE Light Water Reactor Sustainability/ Risk-Informed Safety Margin Characterization (LWRS/RISMC) project, methods, data and tools are being developed with the ultimate scope of improving the safety and operation of the current US nuclear fleet. A set of Industrial Applications (IA) concerning the most relevant safety issues is defined for applying and testing the developed toolkits. The ultimate scope of IA no. 2 is a realistic simulation of natural external hazards that impose threat to a Nuclear Power Plant (NPP). A methodology, which combines a qualified set of tools able to perform advanced risk-informed safety analysis, has been described in a previous paper. In this paper we present the details of the uncertainty quantification (UQ) for the system thermal-hydraulic code and how the UQ is integrated in the global external-events analysis.
