Abstract

The TMI-2 and Chernobyl accidents have shown that nuclear reactor accidents can exceed the conditions taken as the basis for the design. In this situation, the analysis of the source term, i.e. the quantity, timing and form of radioactivity released into the atmosphere, becomes important. Calculations are complicated by differences in reactor containment systems and the complexity of FP transport phenomena. The aim of the Phebus FP project is to investigate, in an in-pile test facility, phenomena governing the transport, deposition and retention of fission products in LWR severe accident conditions, in areas such as the core region, the primary system components and the containment building. These are the result of competing mechanisms, in which thermo-hydraulic, physical, chemical and radioactive processes are coupled. The experimental results are available to validate relevant computer codes.
