Fuel Burnup is one of the usual and also important methods for examine fuel performance and long term behaviours of light water reactores.There are lots of methode for calculating the Fuel Burnup whiches are matrix methodes, semi numerical methodes and numerical methodes.One of the simplest and also accurate methods for calculation of this quantity is based on the heat transfer rate and fission rate which is assumed as a numerical burnup calculation methode. In this article a Westinghouse pressurized water reactor was simulated by MCNPX code based on experimental benchmark datas and fuel burnup was calculated carefully by the mcnpx code. The results of mcnpx code calculation was compared with the results of the methode based on fission rate and heat transfer rate for validating the methode accuracy.the results of combination of the methode based on fission and heat transfer rates and the mvnpx result shows high accuracy of the proposed methode for fuel burnup calculations .
