Abstract

The Phebus-FP experimental programme aims to degrade a bundle of 20 short but otherwise representative PWR fuel rods plus a control rod in the Phebus reactor, and to pass the fission products and structural materials released in the process through a model circuit into a volume representing the reactor containment on a volumetric scale of 1/5000, for the study of aerosol physics and iodine chemistry. This paper describes the current state of Phebus preparation, emphasising the problems arising with later tests and how they are being addressed. Thermal-hydraulic tests have been performed in which steam is injected into the containment vessel in a series of steady states. Before these tests, calculations were performed by various teams using codes that are currently used for reactor calculations (CONTAIN, MELCOR, JERICHO) and some that have been specially written for the Phebus tests. A preliminary comparison of these double blind calculations with the experimental results is presented as an example of the process of test preparation through calculation.
