The goal of this activity is to apply and test Uncertainty Quantification (UQ) methodologies with MELCOR 2.2 against the PHEBUS FPT1 test using three different methodologies and the same MELCOR input deck: RAVEN (Sapienza) DAKOTA coupling with Python scripts (ENEA) DAKOTA with a SNAP/MATLAB mixed approach (UNIPI) A probabilistic method to propagate the input uncertainty was used, considering the aerosol miscellaneous constants as input uncertain parameters. Aerosol suspended mass in the containment’s atmosphere has been selected as FOM.

Abstract
The goal of this activity is to apply and test Uncertainty Quantification (UQ) methodologies with MELCOR 2.2 against the PHEBUS FPT1 test using three different methodologies and the same MELCOR input deck: RAVEN (Sapienza) DAKOTA coupling with Python scripts (ENEA) DAKOTA with a SNAP/MATLAB mixed approach (UNIPI) A probabilistic method to propagate the input uncertainty was used, considering the aerosol miscellaneous constants as input uncertain parameters. Aerosol suspended mass in the containment’s atmosphere has been selected as FOM.File in questo prodotto:
