This paper describes the updating of the sub-cooled boiling model with the more recent and better sub-models. The improved sub-models include: Hibiki and Ishii  correlation for nucleation site density, Kocamustafaogullari  correlation for bubble departure diameter and the S-gamma model of Lo and Rao  for bubble size distribution in the flow.
The new model has been tested against measured data from Debora  and Bartolomei . The results show that improvement in the bubble size prediction has the most significant impact on the accuracy of the model.
