Support device for nuclear fuel plate for fissionable bundle of GFR nuclear reactor with high-temperature heat conduction gas, fissionable bundle including the support device, and nuclear fuel core assembly including the fissionable bundle
Support device for nuclear fuel plate for fissionable bundle of GFR nuclear reactor with high-temperature heat conduction gas, fissionable bundle including the support device, and nuclear fuel core assembly including the fissionable bundle
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.
