This work briefly describes the computer codes RAVEN and DAKOTA, illustrating how to use them in the ambit of uncertainty quantification during PRA thermal hydraulic analyses. The second part shows instead two simple applications of RAVEN code to study SBO transient. In the first one, it has been coupled to RELAP-7 to analyze a PWR, in simplified manner (due to the current limitations of the RELAP-7 code, that is under development). In the second one, it was coupled to RELAP-5 3D code in order to analyze a BWR MARK-1. These two applications demonstrate the potential of the RAVEN code as an optimal tool for the coupling with codes for TH analyses.

Abstract
This work briefly describes the computer codes RAVEN and DAKOTA, illustrating how to use them in the ambit of uncertainty quantification during PRA thermal hydraulic analyses. The second part shows instead two simple applications of RAVEN code to study SBO transient. In the first one, it has been coupled to RELAP-7 to analyze a PWR, in simplified manner (due to the current limitations of the RELAP-7 code, that is under development). In the second one, it was coupled to RELAP-5 3D code in order to analyze a BWR MARK-1. These two applications demonstrate the potential of the RAVEN code as an optimal tool for the coupling with codes for TH analyses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
