  • the wall 10 also has a downwardly sloping surface from a central edge 17 passing through the central longitudinal vertical plane 18 of the container, for example 2 or 3 degrees with the horizontal.
  • the front face 13 comprises two vertically superimposed orifices 21 and 22, located in the plane 18, which will allow both the filling, the emptying and the venting of the container during these operations.
  • the lower orifice 21 is connected to a pipe 28, internal to the enclosure, opening at 24 in the immediate vicinity of the internal upper surface 25 of the lower wall 11 of the container.
  • the pipe 18 is for example made of brass or plastic, fixed in a non-removable manner to orifice 21. It is terminated at 24 by a beveled end.
  • the pipe is arranged obliquely in the container as shown in FIG. 2 in dashed lines, in order to open at the bottom point 26 of the container, and therefore forms an angle of a few degrees, for example 15 ° with the central longitudinal vertical plane 18 from the can.
  • the projecting part 12 is symmetrical and centered relative to the plane 18.
  • the face 9 also comprises means 27 for manually gripping the container, for example comprising two handles 28 and 29, in a manner known in itself.
  • the face 9 also has a lower part 30 of complementary shape to the front face 13 of its upper part 14, as this results from the complementary shape of the lower wall 11 with the upper wall 10.
  • a can as described above can have a height of 60 cm, a width (transverse dimension) of 33 cm, and a length (longitudinal dimension) of 43 cm.
  • the thickness of the wall is for example 0.5 cm, possibly reinforced in a manner known per se to better withstand load and pressure.
  • the internal pipe 23 can be 2 cm in diameter, just like the orifices 21 and 22.
  • the projection 12 has a rectangular face of 15 cm by 10 cm, the distance between the front face and the junction between the end of the rear part 15 with the rest 16 of the upper wall, being of the order of 20 cm.
  • a can of this type weighs around 4 kg when empty for around 90 kg filled with water.

  • the first group 34 of canisters will be described below, the other groups being produced in an identical manner.
  • the means 35 comprise a set of pipes, namely a first pipe 36 which can be connected on one side 37 to at least one water supply 38, via a pressure reducer (not shown) or to a siphon tank (not shown), and connected on the other side 39 to the lower orifice connected to the internal pipe of a first container 40, a second pipe 41 connected on one side to the other orifice 42 of the first container 40 and on the other side 43 to the orifice connected to the internal pipe of a second container 44, a third pipe 45 connected on one side 46 to the other orifice of the second container 44 and on the other side 47 to the orifice connected to the internal pipe of a third container 48, and so on for containers 49 and 50 of the same vertical column 34.

  • Each angle comprises a horizontal plate 53 in lattice, for example rectangular formed by two parallel beams 54 and 55 rigidly connected by three crosspieces 56, 56 ', 56' 'parallels.
  • the external end cross member 56 '' supports, at the end, a vertical scale of width and height slightly greater respectively than the longitudinal dimensions of the cans, and vertical of the column of cans.
  • the ladder comprises for example two vertical beams 57 joined for example by seven parallel bars 58.
  • Two stiffening arms 59 inclined, connecting the end 60 of the part 53 to each beam 57, about two thirds of their height, stiffen the angle.
  • two crosspieces 61 connect the vertices of the vertical ladders, to close the frame on itself.
  • Protective plates (not shown) are also provided and fixed in a manner known per se to the chassis, for example in a padlockable manner.
  • the weight of the cans on the lower plates provides perfect stability for the entire wall.
  • the operators of the radio-protection service responsible for preparing protection before the intervention of operators near an irradiating source, proceed as follows.
  • the chassis 51 is firstly mounted in a manner known per se.
  • the front stiffening cross member 59 is simply omitted at first, so as to be able to place the cans in the chassis.
