Abstract
Abstract A core module for nuclear reactors includes a core support grid having hollow tubes extending upwardly therefrom and fuel assemblies mounted on the upper ends of said tubes with their interiors in communication with the interiors of the tubes. There are a number of control rods around the periphery of each module which are connected by a single control rod yoke, the control rods being guided on the outsides of the core support tubes. The yoke is connected to the core rod drive.
