The purpose of this study is to develop a void fraction correlation based on the void data measured by an X-ray CT scanner. The tests were carried out in an out-of-pile test facility that can simulate the high pressure and high temperature conditions of BWRs. An electrically heated test assembly simulated a BWR fuel assembly on a full scale. The new void fraction correlation has been developed based on the drift flux model, and the prediction accuracy of the void fraction data for this study was Δα (the average of the difference between measurement and calculation) = 0.3% and σ (standard deviation of Δα) = 1.9%. The agreement with other published void fraction data was fairly good.
