Method of Homogenization of Group Neutronic Constants Taking into Account Heterogeneous and Kinetic Effects

A method of taking in account heterogeneous and kinetic effects in the preparation of homogenized group neutronic constants for the diffusion model is described. The results of the application of the proposed technique in the preparation of homogenized group neutronic constants for a fast reactor of type BREST-OD-300 are presented. Consideration of heterogeneous and kinetic effects in the process of homogenization is shown to enhance the accuracy of calculating integral parameters and distributed characteristics that are of importance for safety.
