The paper presents the results of the numerical simulation of 37-pins prototyping fuel assemblies of the reactor plant BREST-OD-300, which are spaced by a bifilar-helix wire wrapper of the "wire to wire" type. It shows the differential static pressure distributions as well as velocity components and the turbulent flow structure in a volume ofpin bundles of the prototyping fuel assemblies.The turbulent flow structure in a volume of pin bundles is analyzed.
