Abstract
For the first phase (1992-1995) of the current research program under nuclear reactor safety enhancement project, the primary objective was placed on the development of an improved cavity design and on the improvement of theoretical models of the separate effects for major severe accident phenomena occurring in the reactor cavity. Also, during the fourth year of this project, small-scale experiments were performed to visualize the fundamental phenomena of boiling in narrow spaces that may exist between the debris crust and the reactor vessel lower head in preparation for the large-scale in-vessel cooling experiment planned for the second phase of the project (1996-2001). Separate effect tests have been performed during the first phase spanning the high pressure melt ejection (HPME) resulting in the direct containment heating (DCH), crust formation during cooling of the high temperature melt, fuel coolant interaction (FCI) in the process of injecting coolant onto the reactor cavity, and the molten core concrete interaction (MCCI). Some research programs were subcontracted with universities. Steam condensation on the containment inner wall was investigated by the POSTECH, while the experimental technique for the simultaneous measurement of particle size and velocity was developed by the KAIST. The second phase experimental projects center about
