IMPROVEMENTS RELATING TO FUEL ELEMENTS FOR NUCLEAR REACTORS

Patent ·
OSTI ID:4049124
A type of complex fuel element is discussed that consists of a tubular framework formed by a plurality of spaced tubes, each containing nuclear fuel. The tubes are disposed either parallel to, or helically around a common axis. In the first mentioned arrangement the cooling fluid follows a helical path around and between the separate tubes, in the second it flows in an axial direction. Other features of this type of element are the presence of a central channel in which a control rod can be inserted, and a protecting graphite sleeve enclosing the cluster-element.
