Definitions

  • the danger zone is generally called the active zone. You can find radioactive emitting products there which justifies the thickness of the walls and / or radioactive emitting products a and p considered as contaminants. Any material leaving an active area is considered to be contaminated and must be placed behind a thick wall (to protect from gamma rays) and in a sealed enclosure (so as not to spread contamination).
  • the present invention describes a process allowing the transfer of an "object” such as material, machine part, barrel of waste, etc. from the active zone to the clean zone, the transport in the clean zone of this object, and transfer in the opposite direction from the clean zone to the active zone while respecting the requirements of confinement and biological protection.
  • object such as material, machine part, barrel of waste, etc.
  • One of the characteristics of the invention is to use a device in two parts to keep the confinement a fixed pre-enclosure and a mobile enclosure.
  • the pre-enclosure remains in place for the entire time necessary to extract an object, take it to a cell and bring back either another object, or the same repaired item, and transfer it to the active area.
  • the top side of the cap is clean and should be kept clean.
  • the inside of the cap is in the active area and is considered to be contaminated and contaminating.
  • the object at least at the time of transfer, is suspended from the stopper.
  • the dimensions of the object are assumed such that by lifting the plug one can extract the object through the hole thus discovered.
  • FIG. 1 is shown in section an active cell composed of a horizontal slab 1 and walls 2.
  • the plug 3 separates the active area 6 from the clean area 7.
  • the object 4 to be transferred is suspended from the stopper.
  • the transfer will take place along axis 5 which is assumed to be vertical for the clarity of the description.
  • Figure 2 shows a pre-enclosure cut by a vertical plane along the transfer axis.
  • the walls 10 delimit a closed box comprising two plugs located on the transfer axis: a lower plug 11 and an upper plug 12.
  • a carriage 14 can move horizontally thanks to an operating rod 15.
  • the pre-enclosure has an interior length 16 such that the passage along the transfer axis is cleared when the carriage is in position 17. We will then call left position 14 and right position 17.
  • a bridge 13 provides sealing between the cell and the pre-enclosure.
  • the mobile enclosure is shown diagrammatically in FIG. 3. It has the shape of a cylindrical or prismatic box with a wall 30 parallel to the transfer axis 36.
  • the upper part is closed but lets a cable 32 pass with a sealing bellows 34.
  • the cable ends with a hook 33.
  • the lower part has a removable plug 31.
  • a seal 35 seals between the enclosure and the pre-enclosure.
  • the upper slab 40 of the cell therefore includes the plug 41 and 1 "object" to be transferred 42 suspended under the plug.
  • the pre-enclosure 43 is placed on the slab so as to respect the transfer axis.
  • the plug 44 and the top plug 46 are in place.
  • the carriage 45 is in the left position.
  • the enclosure 47 is placed on the pre-enclosure so as to respect the transfer axis.
  • the plug 48 is in position.
  • the hook is represented by 49.
  • FIG. 5 represents the first maneuver consisting in securing the plugs two by two:
  • the lower plug 44 of the pre-enclosure is hooked on the plug of the slab 41.
  • the plug 48 of the enclosure is hooked to the upper plug 46 of the pre-enclosure and this assembly is deposited in the carriage.
  • An unclaimed device makes it possible to lock and unlock the two plugs by an external operating rod (not shown in the figure.
  • the carriage 45 is then pulled in an upright position as shown in FIG. 6.
  • This assembly 41, 44, 42 is mounted by the cable in the enclosure 47, FIG. 8 shows this position.
  • the carriage 45 is moved to bring it to the left position in FIG. 9, then the plug 46 is replaced in the upper part of the pre-enclosure (FIG. 10).
  • Said pre-enclosure closes the cell thanks to the sealing of the contacts (the seals 13 in FIG. 2) and thanks to the upper plug 46.
  • Fig. 11 shows another embodiment of the arrangement according to the invention: As a variant, it is possible to envisage equipping the mobile enclosure with a bell 50 sliding just with seals, which makes it possible to avoid contaminating the inside the enclosure.
  • Figure 12 shows such a possibility.
  • a tunnel 60 fixed to the enclosure 47 comprises a thrust chain 61 passing over two pulleys 62-63 returning the movement. For simplicity, no pulleys or slides have been shown for the links of the thrust chain.
  • This device has the advantage of limiting the height necessary for the maneuvers while concentrating on the enclosure the means for lifting the plugs and the object.
  • Such an assembly is particularly practical for bringing the equipment 42 and discharging it in an intervention cell where it will be repaired or overhauled.
  • the present invention has been described in the context of a nuclear industry but applies as well to the transfer of objects contaminated by chemical or bacteriological pollutants as to the transfer of radioactive objects.
