Sever accident (SA) analysis code is effective way of evaluation the sever accident and there are
many types of SA analysis codes. SA analysis codes consisted many logical equations. For the evaluation of fission
products (FPs) release, CORSOR-M model was the role in most of SA analysis code. It was based on the experimental
data of released FPs from real fuel. However, this model was made by fitting with the quantity of
released FPs, therefore it is semi empirical model . This study improved this model using physical data (enthalpy of vaporization). Simulated fuel contained cesium iodide and quadrupole mass spectrometer were
used.
