摘要

本文描述了一种在制备扩散模型均质群中子常数时考虑非均质效应和动力学效应的方法。本文介绍了该技术在BREST-OD-300型快堆均质团中子常数制备中的应用结果。在均质化过程中考虑非均质效应和动力学效应可以提高计算对安全至关重要的积分参数和分布特性的准确性。

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.
