Definitions

  • the invention relates to a transport and / or storage container for radioactive materials, in particular for irradiated fuel elements from nuclear reactors, consisting essentially of a container body with a shielding function, a shielding and a protective cover, a gap-shaped test space being located between the shielding cover and the protective cover.
  • Containers for the transport and storage of radioactive substances are known in large numbers. They generally consist of a container body with a shielding function for -y and ⁇ radiation, which is provided with cooling fins and is closed with a lid system.
  • the cover system consists of a shielding cover with a shielding function against radiation and a protective cover. There is usually a gap-shaped test room between the two.
  • Irradiated or burned fuel elements as well as radioactive waste must be stored temporarily until they are reprocessed or disposed of. Storage generally takes place in water basins with water as the cooling medium. For some time, however, temporary storage with air cooling, especially using natural draft, has been proposed. (DE-A-29 06 629, DE-A-29 13 540, DE-A-27 11 405). To do this, the spent fuel elements must be enclosed in so-called storage containers. The disadvantage of such stores, however, is that the cooling air flow can be loaded with radioactive contaminants that result from leakages in the stored goods container, that is to say from the containers.
  • the present invention was therefore based on the object of providing a transport and / or storage container for radioactive substances, in particular for irradiated fuel elements from nuclear reactors, essentially consisting of a container body with a shielding function, a shielding and a protective cover, with the shielding cover and a protective cover there is a slit-shaped test room in which the escape of radioactive gases can be registered at an early stage.
  • the object was achieved in that one or more ⁇ -measuring probes are installed in the protective cover. It has proven to be particularly advantageous to use a proportional counter as the ⁇ measuring probe.
  • the proportional counter is preferably installed in a cavity in the protective cover, which is closed off with a ⁇ -radiation-permeable layer to form the gap-shaped test space between the shielding cover and the protective cover.
  • the radiation level of q- and ⁇ -rays still present despite the shielding cover on the protective cover permits registration of the radioactive gases escaping into the test space if a ⁇ -measuring probe is installed in the protective cover, the cover of which compared to the test space is chosen that it is still beta-transparent. This makes it possible to register even the smallest amounts of Krypton-85 and Iodine-129 and to detect any leakage as it arises.
  • a transport and / or storage container (1) provided with cooling fins (5) and containing radioactive material is closed with a shielding cover (2) and a protective cover (3).
  • the shielding cover (2) is sealed against the container body (6) by sealing elements (4).
  • a gap-shaped test chamber (7) is located between the shielding cover (2) and the protective cover (3).
  • a measuring probe (8) for measuring radioactive ⁇ -radiation is installed in the protective cover (3), the supply lines (9) of which are led tightly out of the protective cover (3).
  • the ⁇ -emitters e.g. B. Krypton-85 and also iodine-129
  • detectors for ⁇ -radiation can be used as measuring probes, for example special semiconductor detectors and special scintillation detectors.
  • a proportional counter is installed as the ⁇ measuring probe, since it is insensitive to ⁇ radiation and its measuring probe surface can be made as large as desired. This ensures that on the one hand even the smallest radioactive leaks in the test room (7) are detected reliably and immediately and on the other hand also a certain -y-residue radiation above the shielding cover (2) does not interfere.
  • the proportional counter (11) is installed in a cavity (12) in the protective cover (3), which is closed off from the gap-shaped test space (7) with a layer (13) that is permeable to ⁇ rays.
  • the ⁇ -radiation-permeable layer (13) can be applied tightly as a film, for example as a thin metal film or as a metallized plastic film, or else can have remained when the cavity (12) was made from the material of the protective cover (3).
  • counting wires (14) are fastened to insulating bodies (15), which are connected to a voltage supply device or preamplifier and evaluation devices by means of lines (16) through the protective cover (3).
  • the protective cover (3) contains inlets and outlets (21) for supplying the sample gas, the sample gas being used occasionally in the flow or under pressure.
  • the ⁇ -radiation-permeable layer (13) can also be used simultaneously as a pressure membrane for additional pressure measurements.
  • a membrane (17) with associated devices (18) and measuring lines (19) for pressure measurements is additionally installed in the protective cover (3).
  • the functional check of the proportional counter (11) and registration or monitoring is carried out by a central monitoring point.
  • a radioactive a-radiator (20) as a calibration standard in the cavity (12).
  • Pu-238 or radium preparations are suitable as calibration standards.
