Nuclear Fuel Assembly with Thermo-Hydraulic Grid and Thermo-Hydraulic Grid

摘要

The grid comprises two sets of straps intersecting and fixed at their points of intersection, delimiting cells designed to be crossed some by thimble guides and the others by fuel rods, fitted with mixing vanes. It is provided with a surround carrying guide vanes, connected to at least some of the thimble guides. It is suitable for use in fuel assemblies for pressurized water reactors.
