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

摘要

The invention relates to a device for holding nuclear fuel plates (4) having a longitudinal axis (X), that comprises a bottom (6) defining a lower longitudinal end of the holding device and a lid (8) defining an upper longitudinal end of the holding device, the bottom (6) and the lid (8) being rigidly connected together, a plurality of upper holding means (18) for the plates (4) and connected to the lid (8) and a plurality of lower holding means (16) for the plates (4) and connected to the bottom (6) for elastically holding the longitudinal ends of the plates (4) in the width (R) direction of the plate (4) and for allowing the free deformation of said longitudinal ends in the thickness (T) direction of the plate.
