Final seminar of the PHEBUS FP research program from 13 to 15 June 2012

Phebus PF séminaireIRSN and the Institute for Energy and Transport (IET) of the European Commission’s Joint Research Centre (EC/JRC) organize the final seminar of the PHEBUS FP from 13 to 15 June 2012 in Aix-en-Provence (France).

The Phebus FP international research program on severe accidents was launched in 1988 by IPSN (which later became IRSN), in collaboration with the European Commission and EDF. The objective was to conduct integral experiments involving real irradiated fuel rods that simulate as closely as possible the phenomena that can occur in a damaged light water nuclear reactor, in order to validate the simulation software used for calculating the sequence of events during a severe accident and to assess the corresponding radioactive releases into the environment.

Regular scientific seminars were organized during the Phebus FP research program. This 6th and final seminar focuses on the lessons learned from the 5 tests on particular aspects of interest, such as core degradation, fission product release, aerosol transport and fission product behavior in the primary cooling system and in the containment building, as well as iodine chemistry.

A significant part of the seminar will be devoted to the use of the results of the program by the different partners for their safety studies, in particular for the release of radioactive substances into the environment following a core melt accident.

Scientific topics that require the development of further knowledge will also be explained in the light of the impact that insufficient understanding of the physical phenomena involved may have on the assessment of the consequences of an accident, particularly in the light of the Fukushima accident.
