Definitions

  • the invention relates to a storage container for radioactive Fabrics consisting of a coat and floor covering Container body, at least one with interposition a metallic seal assembly with the container body screwed inner cover and one with clearance arranged above the inner cover and under Interposition of another seal arrangement with the Container body screwed on protective plate as outer lid, with the gap between a sensor and the sensor an external display device is assigned.
  • the invention has for its object a storage container of the type mentioned, its metallic Sealing arrangements against the ingress of moisture specially monitored from the outside and thus against corrosion become.
  • the solution to this problem according to the invention consists in that the sensor from a detector for the relative humidity in the space between.
  • The are expediently or the inner cover on gradation ring surfaces of the upper Container body edge supported, sealed and screwed on.
  • the display device preferably consists of a pointer instrument, but could also be from a color change indicator consist. Of course, the measured value of the detector but also at a remote location in a surveillance system are displayed.
  • the invention is based on an exemplary embodiment illustrative drawing explained in more detail. The only figure shows in section a part of a storage container for radioactive substances.
  • the one intended for the storage of radioactive substances Storage container consists of a jacket 1 and a bottom 2 comprehensive container body 3, two with interposition each a sealing arrangement 4, 5 with the container body 3 screwed inner covers 6, 7 and one with clearance 8 arranged above the upper inner cover 6 and with the interposition of a further sealing arrangement 9 screwed to the container body 3 Protection plate 10 as an outer cover.
  • a moderator plate 16 is attached at the bottom of the upper inner cover 6, .
  • the gap 8 is a sensor 11 and the Sensor 11 assigned an external display device 12.
  • the Sensor 11 consists of a detector for the relative Moisture in the gap 8.
  • the detector 11 for the relative humidity is in a Protective plate 10 penetrating hole 15 inserted sealed.
  • the display device 12 is electrical Connection connected and consists of a pointer instrument.
  • the storage tank can be damp with pressure and Gas monitoring detectors are equipped, which in detail but is not shown.
