Title: Modeling and calculation of corium/concrete interaction in a MARK-I containment

Abstract

It is anticipated that following low-pressure corium ejection from a reactor pressure vessel (RPV) into the dry well of a boiling water reactor (BWR) pressure suppression containment, a large amount of hot, mostly molten corium may collect on the dry well floor. The products of concrete ablation pass into the corium pool and start reacting with the various corium constituents, such as zirconium, chromium, iron, and UO{sub 2}, and with other materials released from the concrete, such as SiO{sub 2}, CaO, and Fe{sub 2}O{sub 3}. In order to estimate the effect of the chemical reactions due to these metal/concrete interactions on the amount and energy of gas released into the containment air spaces, a new analytical model has been developed. This model has been extensively tested and validated as the stand-alone subroutine, JIA. This subroutine has also been implemented into the APRIL computer code.
