Abstract

Abstract

In this study,a modified boron tracking model which takes into account the mass diffusivity caused by the turbulence flow is developed and embedded into RELAP5 code based on second order Godunov method.This method is validated by the analytical solution of linearized Burges question.At last,the sensitivity studies of the inlet velocity and refinement of node scheme are performed,which demonstrates the model’s capability of capturing turbulent diffusion transient under low velocity condition and the adaptability to different node schemes.
