Descrizione completa della posizione

Your tasks

Design and implement the uncertainty analysis study for severe accidents in nuclear power plants (includes running sets of accident simulation codes such as MELCOR, MAAP)
Develop and evaluate different Bayesian Network models (from different structural learning and quantification algorithms) for surrogate modelling
Demonstrate the application of these models for two major use cases for nuclear Probabilistic Safety Assessment PSA: examining the impact of uncertainties on the PSA outcomes of interest for model validation and integrating uncertainty analysis findings in PSA models to optimize the structure of accident progression models and their success criteria

Your profile
