Abstract

PURPOSE:To safely and easy perform an operation in the case of drawing nuclear fuel elements from a nuclear fuel assembly by providing grooves along the circumferences near the boundary between the parallel parts and tapered parts of the end plugs in the lower parts of the nuclear fuel elements. CONSTITUTION:The nuclear fuel element 6A is inserted into an insertion hole 4 of the end plug of a lower tie plate 1 of the nuclear fuel assembly and is thereby assembled. The groove 2a having a semi-circular section is provided along the circumference near the boundary between the parallel part of the lower end plug 2A and the inserting tapered part 6A of the end plug continuous to the upper part thereof so that the central point of the groove 2a is set in the spot faced base part of the insertion hole 4 of the end plug of the lower tie plate 1 when the nuclear fuel element 6A is inserted into said hole. The oxide film generated during the use of the nuclear fuel element in a nuclear reactor is absorbed by this groove 2a, by which the sticking of the lower end plug 2a and the lower tie plate 1 is prevented.
