Molten Core Post Test Results

April 2nd 2011 – Questions and Data on Core-Concrete Interactions

Q: What degradation mechanism can result from interaction of molten core and concrete? A: If molten core contacts concrete, a chemical reaction will occur that generates noncondensable gases. This is a slow degradation process relative to many of the other failure mechanisms in play (e.g., hydrogen detonation). Flooding of the drywell will reduce the molten […]
