Fuel assembly with solid end-fitting
Abstract
Abstract The end-fitting of a fuel assembly is constituted by a solid cylinder which is intended to be placed within a stationary cylindrical support tube of a nuclear reactor diagrid, the support tube being provided with openings for the admission of a cooling fluid. The lower extremity of the end-fitting is provided with a recess for the engagement of a member which locks the endfitting in the support tube. The upper extremity of the endfitting is attached to a connecting element which is joined to a fuel assembly box containing the fuel pins. The connecting element is pierced by openings so that the cooling fluid which is admitted into the space formed between the support tube and the end-fitting can circulate between said space and the interior of the fuel assembly box.
