Phebus-FPT0 benchmark calculationsFunded under: JRC-REACTSAFE 5C
This report summarises a set of pre-test predictions made for the first Phebus-FP test, FPT-0. There were many different calculations, representing the first attempt to calculate the whole experimental sequence, from bundle to containment. Quantitative agreement between the various calculations was not good but the particular models in the code responsible for disagreements were mostly identified. A consensus view was formed as to how the test would proceed, and it was found that a successful execution of the test would require a different operating procedure. Critical areas which require close attention are the need to devise a strategy for the power and flow in the bundle that takes account of uncertainties in the modelling and the shroud conductivity, and the necessity to develop a reliable method to achieve the desired thermalhydraulic conditions in the containment.
