TMI-2 accident: core heat-up analysis. A supplement
Following the accident at Three Mile Island, Unit 2, NSAC mounted an analytical program to develop a chronology of what happened in the core during the period when damage occurred. The central effort and key results of this analytical work are described in NSAC-24, TMI-2 Accident Core Heatup Analysis. Several supporting studies contributed to this central effort. These are presented in this supplement. Part I describes a single pin analysis that was made using the FRAP-T5 code. This analysis provided input to the core damage assessment central effort. Part II describes a thermal hydraulic analysis of the core during the accident using the BOIL 2 code. The BOIL 2 analysis of TMI-2 core was performed to provide an independent check on the results of the main core damage assessment effort. Part III provides the as-built design and material characteristics of the TMI-2 core. This supplement will be of greatest interest to analysts who are studying the TMI-2 accident or are investigating how other cores would behave during a boil-down event.
