TL;DR: In this article, an improved end plug assembly has been used to increase the space within a nuclear fuel rod for fission gas expansion, where an outer region of the cavity within the outer body portion of the end plug is undercut relative to an inner region within the cavity of the plug.
Abstract: A nuclear reactor fuel rod includes a fuel tube and an improved end plug assembly having a pair of hollow end plugs which seal opposite ends of the fuel tube. Each end plug has an outer body portion with an outside diameter substantially the same as the outside diameter of the fuel tube and an inner body portion of reduced diameter inserted into an end of the tube. Each plug has a cavity defined therein which increases the space within the rod for fission gas expansion. An outer region of the cavity within the outer body portion of the end plug is undercut relative to an inner region of the cavity within the inner body portion of the plug. One of the end plugs also has an insert fitted into its inner body portion which prevents fuel chips from falling into the cavity of the end plug. A slot is formed axially in a side wall of the insert which allows communication of gas from the tube into the cavity of the end plug.

TL;DR: In this paper, a segmented fuel rod has been used to make its length short, and a lower intermediate end plug includes at least one channel hole, through which a coolant flows into an internal channel of the fuel rod, so that a possibility of causing departure from nuclear boiling ratio (DNBR) of the dual-cooled rod is reduced.
Abstract: An intermediate end plug assembly for a segmented fuel rod can stably support the fuel rod to the end of its cycle even if an interval between the fuel rods becomes narrow due to application of a dual-cooled fuel rod, and reduce excess vibration induced by flows of interior and exterior channels of the dual-cooled fuel rod for obtaining high burnup and output. To this end, the fuel rod has a segmented structure so as to make its length short. A lower intermediate end plug includes at least one channel hole, through which a coolant flows into an internal channel of the fuel rod, so that a possibility of causing departure from nuclear boiling ratio (DNBR) of the dual-cooled fuel rod is reduced.

TL;DR: In this article, a flow rate constrictor was used to control the flow rate of coolant liquid circulating in the assembly head, which can be easily adapted to the operating conditions of the assembly.
Abstract: The apparatus comprises a body (13) housed in the bore (2, 5) of the assembly head (1) and a flow rate constrictor (12) housed in the sodium passage channel (4) in the assembly head (1). The body (13) comprises axial locking fingers (30) in the assembly head, which can be maneuvered by a slide block (20) actuated by an assembly manipulating device (9). The flow rate of coolant liquid circulating in the assembly may be easily adapted to the operating conditions of the assembly.
