Impact vibrations of guide thimbles in nuclear fuel assembly

In nuclear fuel assemblies of pressurized water reactors, guide thimbles (GTs) secure a safe control rod drop. The control rod fall into the GT should be as fast as possible to provide prompt reactor shutdown. The GTs are long thin-walled tubes that are dynamically excited by fuel assembly (FA) comp...
