A new theoretical model, based on the radial temperature distribution of water that has been measured at the subcooled coiling region, is presented for the prediction of an actual quality in the subcooled flow boiling at elevated pressure. The predicted actual quality is converted into the void fraction using Smith's void correlation. Applying a part of the theoretical results, a simple calculation method of void fraction is also proposed. These prediction methods are compared with the experimental results which cover the following conditions ; pressure : 1.0~140.6 ata, heat flux : 1.6×10^4~326×10^4 kcal/m^2h, mass velocity : 130.5~5097 kg/m^2s. Agreement between void fraction calculations and experiments is good.
