Abstract

In this work

3-D flow field analysis for fuel assembly spacer grids or spacer grids with fuel rods were carried out using hydromechanics software.For the spacer grids before and after modification

the calculated hydraulic properties and changes in flow field near the guide vanes were compared.The results show that the rationality of primary modification method for 300 MW fuel assemblies can be validated.
