DEVICE FOR HOLDING NUCLEAR FUEL PLATES FOR A FISSILE BUNDLE OF A NUCLEAR REACTOR OF THE GFR TYPE WITH HIGH-TEMPERATURE GASEOUS HEAT-CARRIER

摘要

A device for supporting nuclear fuel plates (4) with a longitudinal axis (X) including a bottom (6) forming a lower longitudinal end of the supporting device and a lid (8) forming an upper longitudinal end of the supporting device, the bottom (6) and the lid (8) being rigidly connected to each other through a central connecting means and peripheral connecting means, a plurality of upper means (18) for supporting the plates (4) attached to the lid (8), and a plurality of lower means (16) for supporting the plates (4) attached to the bottom (6), ensuring elastic support of the longitudinal ends of the plates (4) in a direction of the width (R) of the plate (4) and allowing free deformation of said longitudinal ends in the direction of the thickness (T) of the plate.
