For the critical power evaluation of BWR fuel, a boiling transition correlation model reflecting the mechanism based on the entrainment and deposition of droplets on the fuel rod surface was derived from the law of mass conservation. Furthermore, a practical correlation model that can predict experimental values with three variables was created.
