چکیده
The MELCOR Core (COR) package calculates the thermal response of the core and lower plenum internal structures, including the portion of the lower head directly below the core. The package also models the relocation of core and lower plenum structural materials during melting, slumping, and debris formation, including failure of the reactor vessel and ejection of debris into the reactor cavity. Energy transfer to and from the Control Volume Hydrodynamics package and the Heat Structure package is calculated. This Reference Manual gives a description of the physical models in the COR package, including the nodalization scheme and calculational framework of the package, the heat transfer and oxidation models, the mass relocation models, and the default lower head model. An alternate (and more detailed) model for debris behavior in the lower plenum of a reactor (BWR or PWR) is available by invoking the Bottom Head package, described in the BH Package Reference Manual.
