摘要： Spacer with a plurality of cells for retaining a plurality of parallel elongated fuel rods (5), extending through the cells, into a fuel rods bundle in a nuclear reactor fuel assembly. The cells are formed from tubular sleeves (1) internally provided with fixed supports (2) and at least one spring means (3) arranged opposite to said fixed supports (2). The spring means (3) are adapted to be pushed into tensioned state through contact with a fuel rod (5) inserted into a sleeve (1) and are formed as a leaf spring (6) which is cut out of the wall of the sleeve (1) and which, when the sleeve (1) is empty, extends into the inner space of the sleeve (1). According to the invention said leaf spring (6) in tensioned position, when the fuel rod (5) is inserted into the sleeve (1), rests in a position substantially coinciding with the wall of the sleeve (1). The leaf spring (6) extends transversally in relation to the longitudinal axis of the sleeve (1) thus allowing the use of cells of relatively short longitudinal extension.
