Definitions

  • the invention relates to a transport container for assemblies. of nuclear fuel and in particular a transport container for new fuel assemblies intended for recharging a nuclear reactor cooled by pressurized water.
  • Nuclear reactors such as nuclear reactors cooled by pressurized water have a core consisting of assemblies nuclear fuel in a straight prismatic shape, usually cross-sectional square and slender.
  • Fuel assemblies generally have a section in the shape of a square whose side has a length about 20 cm, the length of the fuel assembly, in its direction longitudinal, being of the order of 4 meters.
  • the assemblies of fuel have a framework inside which are arranged nuclear fuel rods, essentially along the entire length of the fuel assembly.
  • the framework is constituted itself by transverse grids for holding rods distributed according to the length of the fuel assembly, by parallel guide tubes with pencils engaged in the spacer grids and by end caps end of the fuel assembly.
  • Transport containers ensuring effective protection of fuel assemblies whose pencils are not protected laterally between two spacer grids successive. Transport containers must also be provided to avoid destruction or even limited deterioration of the assemblies of fuel, in the case of a container falling, for example during a transshipment operation of a container, during transport.
  • containers for transporting fuel assemblies that have an envelope sheet metal external made up of two half-shells of slightly shaped near semi-cylindrical attached and fixed one on the other along a frame rectangular disposed along an axial plane of diametrical direction of the container.
  • the container is generally designed for the transport of two assemblies of fuel and has a chassis on which you can attach two fuel assemblies, which rests on a cradle fixed via shock-absorbing support elements inside the half-shell bottom of the outer shell of the container.
  • the support frame and holding fuel assemblies is pivotally mounted on the cradle, by one of its ends, so that it can be moved between a loading position of fuel assemblies in which the support is substantially vertical and a transport position in which the fuel assembly support frame rests on the cradle in a substantially horizontal position.
  • the fuel assembly support frame has, generally, a T-shaped cross section that has a support base for fuel assemblies and a center partition longitudinal direction perpendicular to the base.
  • the support base for fuel assemblies and the middle partition delimit, on the part and on the other side of the middle partition, two housings in each of which can place a fuel assembly.
  • Fuel assemblies are held on the chassis, by means of flanges articulated on the lateral edges of the base and on the upper edge of the central partition of the chassis, so that the flanges can be moved between a open position in which the housing for a fuel assembly is accessible and a closed position in which the flanges maintain a fuel assembly.
  • the flanges are assembled between them, in their closed position, by sets with screw and nut and are arranged along the length of the chassis, so that come to bear on the fuel assemblies placed in the housings of the chassis, at each of the successive spacer grids fuel assemblies.
  • Transport containers are designed so that the assemblies fuel placed side by side in the transport position cannot in no case constitute a critical mass leading to the start of neutron chain reactions. It is usually necessary to place neutron-absorbing elements between the fuel assemblies in position transport in the container, so as to avoid any risk of criticality.
  • the neutron absorbing means of the assemblies of fuel could be insufficient and the containers did not have not a structure allowing an effective containment of the matter fissile in case of deterioration of the fuel assembly inside the container.
  • the fuel assembly is neither protected nor confined inside the outer envelope of the container, the chassis not comprising that means for holding the fuel assemblies, under the form of flanges spaced along the longitudinal direction of the assemblies fuel, in the same way as the spacer grids.
  • the object of the invention is therefore to propose a container for transport for nuclear fuel assemblies of prismatic shape straight with an external envelope and an internal structure delimiting the less a receiving housing for maintaining a fuel assembly having side faces arranged in a straight prismatic surface and a end face at each of the longitudinal ends of the housing and comprising an assembly for receiving and holding at least one assembly of fuel comprising a support frame of at least one assembly of fuel comprising at least two bearing walls of two lateral faces a fuel assembly and at least one element pivotally mounted on the frame between an open position to give access to the housing the fuel assembly and a closed position in which the element ensures closure of the fuel assembly housing, this container transport allowing effective protection of the assembly (s) of transported fuels and to confine the fissile material contained in the fuel assemblies to prevent fissile material from forming spreads inside the outer envelope of the container in case of deterioration or destruction of fuel assemblies.
  • the internal structure constitutes a housing for receiving at least a fuel assembly that can be opened to provide access to the fuel assembly housing.
