Energy group structure has a significant effect on the results of multigroup transport calculations. It is known thatUO2–PuO2 (MOX) is a recently developed fuel which consumes recycled plutonium. For such fuel which contains variousresonant nuclides, the selection of energy group structure is more crucial comparing to the UO2 fuels. In this paper, in order toimprove the accuracy of the integral results in MOX thermal lattices calculated by WIMSD-5B code, a swarm intelligencemethod is employed to optimize the energy group structure of WIMS library. In this process, the NJOY code system is used togenerate the 69 group cross sections of WIMS code for the specified energy structure. In addition, the multiplication factor andspectral indices are compared against the results of continuous energy MCNP-4C code for evaluating the energy groupstructure. Calculations performed in four different types of H2O moderated UO2–PuO2 (MOX) lattices show that the optimizedenergy structure obtains more accurate results in comparison with the WIMS original structure.
