Abstract

A nuclear fuel element of the type having a stack of fuel tablets retained in a sealed sleeve by a support piece fixed to the latter by a retaining device, the friction of which, on the sleeve, when it is placed in posn., opposes its displacement along the sleeve axis, is improved by a retaining device which consists of a shaped piece of strip of constant thickness, the edges of which are separated in its rest position by a gap extending along its length, and which has a transverse size in its state of rest greater than the i.d. of the sleeve and can contract elastically to this dia.
