Abstract
A nuclear reactor fuel assembly with two support plates and a holding rod connecting the two support plates rigidly with mutual spacing, the holding rod having a longitudinal axis passing through both support plates, and being held at one end in a lead-through in one of the two support plates, includes, in the lead-through, an elongated holding body for the holding rod rotatable about the longitudinal axis thereof, and displaceable in direction of the longitudinal axis thereof coaxially with the lead-through; the holding body being rigidly connectible by a rotation relative to the holding rod about the longitudinal axis thereof to an end of the holding rod and tightenable against a holding shoulder in the one support plate and detachable from the holding rod; and a spring element braced against the support plate and pressing the holding body elastically against the holding shoulder.
