Description

The bundles of the CORA-17 and CORA-18 Severe Fuel Damage (SFD) experiments, both of BWR type, are evaluated on the basis of a detailed microstructural analysis and in comparison with available results of the test CORA-16 and separate effects investigations. The evaluation as performed up to now is concentrated on the failure of the absorber unit and its influence on the fuel rod degradation. In CORA-17 fuel rod fragments and dispersed metallic melts were identified in the effort to understand the reasons and consequences of the quenching phenomena (temperature and hydrogen peaks). With CORA-18 no influence of the larger bundle size was found. (orig.)
