The invention relates to a computer-assisted method for determining an optimal core-loading pattern for a nuclear reactor core. Respective positions of nuclear fuel assemblies are tested by these means in order to assign optimal positions to the assemblies and proceed with loading the reactor. The reactor core comprises cells positioned symmetrically relative to axes of symmetry, with standard assemblies being intended to be inserted into respective cells. These standard assemblies for future loading are distributed according to the number of production cycles that they have previously undergone. Additionally, groups of cell positions that are symmetric relative to the axes of symmetry are identified, and the number of symmetric positions in each group is counted. Families of standard assemblies are formed, such that the standard assemblies of the same family have at least similar burnups. Each family comprises a number of standard assemblies that corresponds to the number of positions of one of the groups. Numerical simulation is used to test the loading pattern formed by the standard assemblies in initial positions and then the positions of standard assemblies are switched while maintaining the previously formed families of assemblies. Numerical simulation is used to test the loading pattern formed by the standard assemblies in the switched positions relative to a predetermined criterion, this step being repeated until at least one candidate pattern for loading the reactor is obtained.
