Abstract
The problem of verifying computational results for liquid-metal coolant flow in nuclear reactor fuel assemblies with spacer grids is addressed. The verification results demonstrate that the CADFlo software package provides high accuracy in simulating both laminar and fully developed turbulent flows. For heat transfer problems involving liquid-metal coolants in fuel assemblies, good agreement is obtained between the computed temperature distributions and hydraulic resistance coefficients and the experimental data.
