This research utilizes the MATLAB PDE Toolbox for modeling 3D static reactors with hexagonal fuel lattices. Along with its other versatile capabilities, this computational tool is capable of modeling multigroup neutron diffusion equations for 3D nuclear reactor cores with a fair degree of precision based on the finite element method. This research's product is a 3D reactor statics computer program that has been developed based on the MATLAB PDE Toolbox. The program can be applied to reactor cores with hexagonal lattices, such as VVER-type nuclear reactors. The 3D VVER-440 benchmark has 25 hexagonal assemblies arranged across the core's diameter. The core has one-twelfth mirror symmetry, a hexagonal lattice pitch of 14.7 cm, and a 25.0 cm thick reflector at the top and bottom of the 250.0 cm high 3D core. A 3D model of the one-twelfth core is created and imported into MATLAB. The developed algorithm uses this model to define the core's geometry and solve the two-group neutron diffusion equations. The model can deduce the effective multiplication factor (keff), neutron flux distribution profile, and normalized assembly power and compare them with reference benchmark results. Based on this comparison, the accuracy and efficiency of the developed algorithm have been validated.
