The qualitative aspects of reflood heat transfer in the system codes (e.g., RELAP5/MOD2, TRAC-PF1/MOD1, COBRA-TF, etc.) can be represented with a generalized boiling curve. The anchor points used to specify the boiling curve are the critical heat flux (CHF) temperature (T/sub CHF/) and the minimum flow boiling temperature (T/sub min/). The cooldown during the quenching process is affected by the minimum film boiling heat flux. This aspect of the quenching process has not been studied as much as the CHF phenomenon. The purpose of this paper is to compare several rewetting correlations. These correlations were implemented in a special version of RELAP5/MOD2 computer code. Good comparison between several FLECHT-SEASET data and predicted rewetting temperatures was obtained when a new modified formulation of Henry rewetting correlation was used to account for the mass rate dependence.
