The ‘Fuel Rod Analysis ToolBox’: A general program for preparing the input of a fuel rod performance code

Abstract This paper gives an overview of the new ‘ Fuel Rod Analysis Toolbox ’, which is a program for the pre-processing of input data for fuel rod performance codes with a graphical user interface. It consists of three different modules that can handle several tasks such as data condensation, merging and synchronization. The ‘ Fuel Rod Analysis Toolbox ’ helps: • to reduce the amount of input data, • to simplify the setup of input files for complex data sets with input from experimental data as well as input resulting from neutronics or thermo-hydraulics codes, and • to reduce computation time. These advantages are already evident for complex fuel rod analyses employing a conventional one-and-a-half-dimensional code but they become even more important for two- or three-dimensional approaches.
