Description
Summary:In risk studies, paramount attention is paid to hypothetical accidents with nuclear reactor core melt down because of possible physical health impacts resulting from this type of accidents. In the Federal Republic of Germany the research project “core melting” was initiated by the Federal Ministry of Research and Technology in 1971 in order to investigate melt down phenomena. One of the main objectives within the research project is the development of experimentally verified models and computed codes to predict the radioactive source term released to the environment during degraded core accidents. It is the purpose of this paper to summarize the present state of the art obtained so far and to show current results of consequence analyses. The analyses, which up to now do not cover all important fission product release paths, are valid for large 1300 MW KWU-type PWRs demonstrating low releases of cesium and iodine to the environment.
