Simple subcooled boiling model. [PWR; BWR]

Conference ·
OSTI ID:6376913
During the assessment of TRAC-PD2 and RELAP5/MOD1 codes with the FRIGG rod bundle data, it was found that these codes did not include the model(s) necessary to describe the subcooled boiling regime in heated channels. To remove this deficiency, a simple subcooled boiling model is proposed in this paper. The model consists of the following elements: a correlation for determining the net vapor generation point; and a nonequilibrium vapor generation rate.
