The Phebus Fission Product and Source Term International Programmes

Since the TMI2 accident in 1979, an important international effort has been made in research on severe accidents, involving integral experiments, separate-effect tests and model developments. The international Phébus FP programme, initiated in 1988, has played and is still playing an important role in this landscape. After a short description of the facility and of the test matrix, the main outcomes and results of the first four integral tests are provided and shortly analysed. Several results were unexpected and some are of importance for safety analyses, particularly concerning fuel degradation, cladding oxidation, chemical form of some fission products, especially iodine, effect of control rod materials on degradation and chemistry, iodine behaviour in the containment.
