CONSTRUCTIONS FOR PRODUCING RADIO ZOTOPES, HEATING ASSEMBLIES THAT HAVE SUCH DESIGNS, AND WAYS OF APPLICATION OF SUCH DESIGNS

摘要

1. The design for obtaining radioisotopes for use in the fuel assembly (100) of a nuclear reactor, containing! a butt pad device (150) shaped to be installed below the butt pad (114) in a nuclear reactor fuel assembly (100) in the axial direction, wherein the butt pad device (150) includes at least one retaining hole (160) , wherein the butt pad device (150) is made of a material that essentially retains its physical and neutron properties under the influence of a neutron flux in an operating nuclear reactor, and! at least one irradiated target (170) configured to be substantially converted into a radioisotope under the influence of a neutron flux in an operating nuclear reactor, wherein at least one irradiated target (170) is located in at least one retaining hole (160). ! 2. The structure according to claim 1, in which the tool (150) of the butt pad further includes at least one hole (155), the shape and location of which allows the passage of the fuel rod (18/19) of the fuel assembly (100) of the nuclear reactor through tool (150) of the butt plate and then into the butt plate. ! 3. A structure according to claim 2, wherein the at least one hole (155) is shaped to seat the fuel rod (18/19) such that the butt strip tool (150) is locked against the butt strip (114). ! 4. The structure of claim 1, wherein the butt strip tool (150) further includes at least one lateral extension (165) connecting the butt bevel tool (150)
