MCNPX computer code is used to design a three-dimensional model for a typical Pressurized Water reactor (PWR) core. Uranium Nitride fuel (UN) was tested for the reactor and the results were compared with a typical UO2 fuel. Neutron spectrum, power distributions, plutonium isotopes productions, and kinetics and safety parameters were evaluated. It w...

... computer code package [17] is used to design a threedimensional model to the reactor core, the model is extended up to the pressure vessel as illustrated in Fig. 3. The full dimensions and compositions of the fuel rods, fuel enrichments, burnable absorber and control rods are incorporated in the model. Burnup module (or cards) in the MCNPX code are used to burn and operate the reactor core in a typical operating conditions as indicated in a former study [16]. The total oper- Fig. 5 illustrates ...
