In-core fuel management (ICFM) is known as one of the most complicated tasks of reactor core design for determining an optimal core loading pattern of available fuel assemblies. This work presents the development of a Success-History based Adaptive Differential Evolution (SHADE) method for the ICFM problem of a VVER-1000 reactor. SHADE is an advanced version of differential evolution (DE) method, which is originally developed for continuous-variable multi-objective optimization problems. However, the ICFM problem of a nuclear reactor works with integer variables corresponding the positions of fuel assemblies in the core. Several discretization approaches have been proposed and investigated for a discrete SHADE method. Comparison among the discretization approaches has been conducted based on numerical calculations for optimizing fuel loading pattern of a reference VVER-1000 core. Based on the numerical calculation and the comparison, a suitable discretization approach has been selected for the discrete SHADE method for further development.
