Analysis of the late core melt progression phase of severe reactor accidents using the MELPROG (MELt PROGression) code
The two-dimensional (r-z) MELt PROGression (MELPROG) computer code is being developed to analyze severe light water reactor accidents from accident initiation through vessel failure. The MELPROG code is comprised of several explicitly linked modules that analyze different aspects of an accident. This paper describes the MELPROG models that are used to study the late core melt progression phase of severe accidents. Particular attention is given to the DEBRIS module that analyzes melt progression in particle beds that can form in the reactor core and the lower plenum during accidents like Three-Mile Island. Other modules in the MELPROG code are briefly described and results from a sample calculation are presented to demonstrate the capabilities of the code.
