Abstract

This State of the Art Report has been prepared under the European Commission's Reinforced Concerted Action (RCA) on Molten Fuel Coolant Interactions (MFCI), which was undertaken as part of the Reactor Safety specific programme of the Third Framework Programme. It has four major objectives: to summarize the current state of knowledge; to record the progress made during the RCA; to provide a synthesis of the understanding of MFCI in the European Union; to provide an overview of the subject in sufficient detail that it may be used as an input for decisions of future research in this area. MFCI are studied because there is the possibility of an interaction occurring during a postulated severe accident that is sufficiently energetic to generate missiles that threaten the containment. This is one of the few mechanisms that have been identified that could lead to relatively early failure of the reactor containment in a severe accident, and to a potentially large source of fission products to the environment. This report is concentrated on topics relevant to the assessment of such interactions in a light water reactor, with emphasis on the interactions that may take place when part of the core relocated into residual water in the reactor's lower head. Associated issues, such as the break-up of melt streams to give potentially coolable debris are also covered.
