Iodine behaviour in the two integral tests Phebus FPT-0 and FPT-1: Implications for severe accident iodine chemistry codes Development
PHEBUS FP is an international programme whose objective is to investigate, through a series of in-pile integral experiments, key phenomena involved in light water reactor (LWR) severe accident. Two experiments have been successfully performed FPT-0 and FPT-1: the first test FPT-0 in December 1993 with trace irradiated fuel, the second test FPT-1 in July 1996 with re-irradiated fuel. These two tests have shown quite unexpected phenomena, particularly in the field of core degradation and fission product behaviour. Concerning the latter, the most unexpected result of the PHEBUS tests was the extensive release of control rod materials including silver during fuel degradation. The fission product transport and chemistry, both in the circuit and the containment, was strongly influenced by the presence these materials.
