International Research Progress of CFD Application in Analysis of Nuclear Power System

This paper introduces the latest international research progress of CFD application in nuclear reactor system analysis.CFD method has been applied to a few 3-D single phase transient simulations,including flow field modeling of the reactor cores,assemblies,and vessel plenums.On the other hand,CFD method applied to reactor system still needs further validation and benchmarking,meanwhile,the application of CFD also needs to be studied,including the setup of the Best Practice Guidelines （BPG）.Furthermore,CFD codes are used to couple with thermal-hydraulic system codes or neutronic codes.Eventually,in two phase field and turbulence modeling,CFD codes are still being developed.
