We report on the analysis of the priority cases of the IAEA co-ordinated research project Fumex-III for the ongoing validation of the Transuranus fuel performance code. We focus on a) fuel centre temperatures in re-fabricated high-burnup fuel rods, b) local concentrations of Pu and Xe and c) cladding failure. We provide a systematic comparison in the context of the existing validation base of the Transuranus code, and demonstrate the added value of applying data from independent experiments.
From the application of the Transuranus code to one LOCA and one RIA case, preliminary conclusions are drawn defining needs for further development of sub-models, as well as needs for complementary local 2D and 3D simulations. Finally, recommendations are given for a future research project on fuel performance simulations.
