Definitions

  • the invention relates to a container in particular for a radioactive substance according to the preamble of claim 1.
  • Such a container is known from DE-OS 33 43 166. Its inner container is in one piece. It contains a rod, which consists of a steel tube filled with boron carbide and which absorbs neutrons to prevent a critical configuration of fissile radioactive substances.
  • the inner container is not to contain any neutron-absorbing rods, since these are gradually becoming less effective, the diameter of the inner container must not exceed a certain limit if a critical configuration is to be avoided. If you want a large filling volume of the inner container, the height of this inner container can be chosen to be very large. A slim inner container with a large height, however, leads to an unwieldy container, in particular filling and emptying the inner container is difficult.
  • the invention has for its object to provide a container that can have a more favorable ratio of diameter to height.
  • a radioactive liquid substance contained in both is spatially separated from one another, which causes neutron-physical decoupling.
  • This decoupling can be further improved by suitable selection of the filler for the filling space.
  • Suitable filler is, for example, natural water, which is a moderator substance, but also has a large capture cross-section for thermal neutrons and also has a shock-absorbing effect and dissipates heat well from the inner container to the outside.
  • the neutron-physical decoupling can be further improved by the main and / or secondary container being made of neutron-absorbing material and / or by the filler for the filling space of the outer container containing a neutron-intensively absorbing substance.
  • the sub-claim 2 is directed to an advantageous development of the container according to claim 1, with which it can be ensured that a filler consisting of a liquid such as water is kept in overpressure in the filling chamber, so that in the event of a leak in the main or secondary container filler penetrates the main or secondary container and radioactive liquid substance is difficult to escape from the main or secondary container.
  • the container has a hollow cylindrical outer container 2, which is a cast part and is provided on the outside with cooling fins 2a.
  • An inner container is arranged within the outer container 2 and has an elongated main container 3 in the form of a hollow cylinder child and six secondary containers 4 in the shape of an elongated hollow cylinder.
  • the longitudinal axes of the main container 3 and the sub-container 4 are parallel to each other, and the main container 3 is attached coaxially to the outer container 2.
  • the main container 3 With its lower end, the main container 3 is held on the inside of the bottom of the outer container 2 in the center thereof with a shock absorber 5. The upper end of the main container 3 is guided through the center of a lid 6, which is screwed tightly to this outer container 2 at the upper end of the outer container 2.
  • the main container 3 On the inside of the cover 6, the main container 3 has an outer flange 7, while on the main container 3 on the outside of the cover 6 there is a slot nut 8.
  • a sleeve 9 made of an elastomer, e.g. Rubber with flanges on both ends.
  • One flange rests on the outer flange 7 of the main container 3, while on the other flange lies the slot nut 8, with which the main container 3 is clamped to the cover 6 with its outer flanges via the sleeve 9.
  • the sleeve 9 thus forms a further shock absorber on its outer flanges.
  • While the main container 3 of the inner container is arranged centrally in the outer container 2 and in a regular hexagon, which is located in a cross section of the outer container 2, the six secondary containers 4 of the inner container are each arranged in a corner of this hexagon. They are separated from the main container 3 and closed at both ends.
  • the main container 3 projects beyond the upper ends with its upper end and the lower ends of the secondary containers with its lower end ter 4.
  • This sub-container 4 are supported with support webs 10 on the main container 3.
  • a connecting pipe 11 with a continuous gradient in the direction towards the lower end of the main container 3 leads to this main container and from the upper end of each of the sub-containers 4 a connecting pipe 12 with a continuous slope in the direction of the upper end of the main container 3 to this main container 3.
  • a further immersion tube 14 leads to the filling and emptying of the filling space 37 in the outer container 2 to the bottom of this outer container 2.
  • a ventilation and ventilation nozzle 15 which closes automatically when a coupling part of one, not shown, is closed Hose line is removed, and which is clearly visible in FIG 3.
  • sealing rings 16 can also be seen, which are located between the cover 6 and the outer container 2.
  • a screw 17 can be seen, with which the lid 6 is screwed onto the outer container 2.
  • a hollow cylinder 19 open on the inside of the cover 6 is screwed tight and sealed with a sealing ring 20.
  • a coaxial coil spring 23 which is supported at one end on the bottom of the hollow cylinder 19 and at the other end on a piston 21 which has a metal bellows 22 surrounding the open end of the hollow cylinder 19 on the inside of the Cover 6 screwed tight and with a sealing ring 24th is sealed.
  • the active surface of the piston 21 consisting of its outer surface thus belongs to the inner surface of the outer container 2.
  • Natural water as a liquid filler is pumped through the immersion pipe 14 into the filling space 37 of the outer container 2 and the coupling part of the hose line, not shown, is uncoupled from the ventilation and ventilation connection 15 when water escapes through this ventilation and ventilation connection 15.
  • This ventilation and ventilation nozzle 15 thereby closes automatically, and by pumping further on the immersion tube 14, the water in the filling space 37 of the outer container 2 receives an overpressure by which the piston 21 compresses the coil spring 23 without the piston 21 being seated on the hollow cylinder 19.
  • a hose line, not shown, for supplying water is decoupled from the immersion tube 14, which has a filler neck, not shown, in the cover 6, which also closes automatically when the coupling part of this hose line is removed from it.
  • the pressure then exerted by the compressed helical spring 20 via the active surface of the piston 21 on the water in the filling space of the outer container 2 maintains the excess pressure in this filling space.
  • the outer container 2 is also provided with a protective cover 25 which is screwed onto the outer container 2 with screws 26 above the cover 6 and is sealed with sealing rings 27 inserted in the outer container 2.
  • This protective cover 25 receives the upper end of the main container 3, the ventilation and ventilation connection 15 and the filler connection (not shown) of the immersion pipe 14 and is foamed on the outside with polyurethane foam 28.
  • a pressure relief valve 40 (or a rupture disk), which leads from the filling space 37 to the outside, can advantageously be attached to the outer container 2.
  • a pressure relief valve 40 (or a rupture disk), which leads from the filling space 37 to the outside, can advantageously be attached to the outer container 2.
  • overpressure valve 40 after the excess pressure that arises in the filling chamber 37, and water vapor escapes to the outside. To form this water vapor, decay heat is removed from the radioactive liquid substance in the inner container.
