Abstract
A nuclear fuel assembly comprises two end pieces connected by guide tubes. Grids are distributed along the guide tubes and define passages distributed according to a regular pattern. Some of the passages receive the tubes. Other passages retain fuel elements parallel to the tubes. Individual sleeves containing a burnable poison are carried by the tubes, each in a space bounded by one grid on one side, by an other grid or an end piece on the other side. The length of the sleeves is selected for allowing differential thermal expansion of the tubes and grids. One end of each sleeve may be secured to lugs of an associated grid.
