Sensitivity analysis of debris bed models to determine parameters’ influence on criticality
The goal of the project „SBN-KEK“ is the evaluation of the criticality potential in debris beds which are formed after severe accidents in LWRs. The development of an exhaustive criticality database is one of the current R&D priorities for a safe decommissioning of the damaged Fukushima reactor units.
In this thesis, you will carry out the sensitivity analysis of different debris bed models, which are considered in the overall project based on the current conditions of Fukushima units 1, 2 and 3.
The objective is to identify the most influencing parameters on criticality (i.e. the neutron multiplication factor keff) using the software tool SUSA (Software for Uncertainty and Sensitivity Analyses), which has been developed by the GRS (Gesellschaft für Reaktorsicherheit).
