Abstract

Abstract

The coarse mesh finite difference method with discontinuity factor correction is one of the effective methods to realize the core transient three-dimensional numerical simulation.The calculation method of coarse mesh interface discontinuity factor and the boundary albedo determines the precision in the process of real-time simulation.In the process of calculation of discontinuity factor and boundary albedo, the fine cell calculation and coarse mesh homogenization process is eliminated.Directly under the condition of the coarse cell, based on the nodal expansion method and nonlinear iterative strategy, coarse cell interface discontinuity factor ratio and boundary albedo are deduced.The corresponding calculation programs are developed.From a typical boiling water reactor 3Dtransient simulation benchmark, the method is proven to be available.The static and transient precisions both in space domain and time domain, are equivalent with that of the advanced nodal method, and the computational efficiency is superior to that of the advanced nodal method.This method provides a feasible choice for the development of full scope simulator of transient calculation of three-dimensional core model.
