Sensitivity analysis in core diagnostics

In the CORTEX project, methods to simulate neutron flux oscillations were enhanced and machine-learning based tools determine causes of measured developed, using results simulations as training validation data. For a selected combination those tools, several sensitivity analyses performed assess their robustness trustworthiness. The simulated tool CORE SIM+. It calculates three-dimensional field oscillations, which can be used response detectors at given locations. analysis, assumed caused by vibration one fuel element. was investigated how input parameters like core loading pattern, burn up elements, neutronic data, geometry details vibrating element, chosen detectors, other noise source amplitude element vibrations, affect oscillations. A three dimensional fully convolutional neural network had been developed trained during project cause location perturbations causing measurements in-core in pressurized water reactors. this tested applying it detector readings created analysis.
