Definitions

  • the invention relates to a container for the transport and storage of bio-harmful substances, in particular radioactive substances, consisting of a base body and a lid fastened with screws thereon via two concentric, spaced-apart sealing rings, which is provided with a line, the contact surfaces of Base body and cover are plane-parallel in the area of the two sealing rings.
  • Containers for the transport and storage of radioactive materials usually have a base body and a sealed lid and are also provided with connecting elements, via which it is possible to set certain conditions in the interior of the container after loading, in particular the type of Filling gas and its pressure.
  • the loaded containers are filled with helium and the pressure is set to 0.5 bar absolute. This is done to avoid corrosion, to create a defined pressure drop for radiation protection reasons and also to be able to offer helium for a leak test of the cover seal.
  • These connection elements may represent weak points in the container and are usually also very expensive to manufacture.
  • the figure shows schematically an exemplary embodiment of the container in longitudinal section.
  • the container consists of a base body (1) and a lid (2). They enclose the interior of the container (6) in which the radioactive material is located.
  • the cover (2) is fastened to the base body (1) with the aid of screws (7).
  • the contact surfaces of the base body (1) and cover (2) are designed plane-parallel.
  • the line (5) opens into the space between the two sealing rings (3, 4).
  • a connection to various systems, such as a vacuum pump, inert gas supply or leak test device, can be established via this line (5).
  • the two concentric sealing rings (3, 4) are inserted and the lid (2) put on. It is also possible to attach the sealing rings (3, 4) to the cover (2) beforehand and to place them together with the cover on the base body (1).
  • the interior of the container (6) is evacuated, for example with a vacuum pump, via the line (5).
  • the flooding is then carried out with the desired gas, either pure helium or another inert gas, to which helium has been added to carry out a leak test.
  • the inner sealing ring (4) is also pressed in by finally tightening the screws (7) until the base body (1) and cover (2) touch.
  • Metal or plastic can be used as the material of the sealing rings, a combination of the two materials is also possible. In the case of containers for long-term interim storage, metal seals are preferably used.
  • a softer material is preferably chosen for the outer sealing ring (3), i.e. a seal with a smaller spring constant than for the internal sealing ring (4).
  • a gas sample can be drawn from the container interior (6) and a controlled pressure compensation between the container interior (6) and the environment can be established.
  • the line (5) is connected to a gas collection or analysis device and a ventilation system. Then you lift the cover (2) so far that the inner sealing ring (4) is no longer in engagement. This creates a connection to the interior of the container (6).
