Definitions

  • the invention relates to a method for producing a Container for the transport and storage of radioactive radiating material as well as a container with which to radioactive radiating material can be transported and stored can.
  • Such containers have so-called in the embodiment "Castor container” was very important in the past obtained. They serve radioactive material, for example spent fuel elements from nuclear reactors, from the power plant to an intermediate or final storage point transport.
  • the invention is based on these aspects Task based on a method for producing a corresponding Container or one of the aforementioned Provide sufficient container.
  • Radioactive rays include alpha rays, beta rays, Gamma rays and neutron rays.
  • Alpha and Beta rays generally have such short ranges that for their shielding low material thicknesses (order of magnitude: a few millimeters) are sufficient.
  • the invention is based on the knowledge that the Shielding effect of such steel-reinforced concrete containers a special selection of heavy concrete between steel walls can be achieved.
  • the essential aspect of this process is the special application technique of heavy concrete between the called metal walls.
  • cement stands for everyone Types of hydraulic binders. To be favoured however, Portland cements are used, namely Portland cements of type CEM I 42.5 or higher (e.g. CEM I 52.5).
  • Surcharges that have the required bulk density are for example barite, ferrophosphorus, magnetite, iron (Steel), lead, hematite and chilled cast granulate and others
  • Metals, especially heavy metals, with the supplements can be used individually or in mixtures.
  • this term particularly includes steel pipes and here in particular steel pipes with a circular cross section, albeit other cross-sectional shapes, for example Polygons can be used.
  • One embodiment of the method provides an inner tube to use which is closed at its upper end and is shorter than the outer tube.
  • outer tube and inner tube for example on a floor (one Plate) and then not just the annulus between the inner and outer pipe filled with the aggregate, but also the space between the top closed end of the inner tube and the upper edge of the outer tube. Subsequently In addition to the annulus, the space between the closed end of the inner tube and the top edge of the outer pipe with the cement / water / plasticizer suspension filled. In this way a kind arises "Concrete cover", which in later use (after turning around 180 °) forms the bottom of the container.
  • a metal / steel plate attached to the upper edge of the outer tube for Example can be screwed on or welded on.
  • the stability of the container is significantly improved, if reinforcement in the Annular gap or that between the upper closed end of the inner tube and the open end of the Outer tube trained space is inserted. hereby is also the heat dissipation during the hydration of the cement improved.
  • Such reinforcement can, for example, consist of one Reinforcement cage exist, which is essentially about total volume of the annular gap or the named Extends.
  • the width of the annular gap is, for example 20 to 30 cm. Also the “concrete floor slab” can have an appropriate thickness.
  • the container can be designed in this way be that the inner tube at a distance from the lower end of the Outer tube ends, is closed at this end and between the closed lower end of the inner tube and a heavy concrete slab is available at the lower end of the outer tube which is material-locking with that in the annular gap Is heavy concrete.
  • This embodiment describes the container in Use state. Inner and outer tubes are used for the production arranged rotated by 180 °, as described above.
  • the heavy concrete can be armored, the armouring for example there is a reinforcement cage.
  • Outer tube 10 and inner tube 12 stand with their respective lower end on a lid 14, the lid 14 via two concentric flanges 16, 18 with an internal thread corresponding external thread at the lower end of the outer tube 10 and the inner tube 12 is screwed on.
  • the inner tube 12 is shorter than the outer tube 10 and ends correspondingly at a distance from the upper edge of the outer tube 10.
  • the inner tube 12 is at the upper end with a steel plate 20 locked.
  • the annular gap 22 and Room 24 filled with a reinforcement cage 26 made of steel ( Figure 2).
  • the reinforcement can also be on the inner wall beforehand of the outer tube and / or on the outer wall of the inner tube attached, for example welded on.
  • a heavy concrete aggregate is added to the annular gap 22 and the space 24 filled, which here from 20 wt .-% barite Grain fraction 4/8 mm, from 30 wt .-% barite of the grain fraction 8/16 mm and 50 wt .-% steel balls with a diameter between 5 and 8 mm in a homogeneous mixture (Figure 2).
  • the outer tube 10 has two, offset by 180 ° to each other Openings 30, in each of which a tubular Adapter 32 is screwed in.
  • the openings are at the bottom End of the outer tube 10 is arranged.
  • a delivery line is then connected to the adapter 32 (shown schematically by arrow 34) connected.
  • a cement / water / plasticizer mixture is then fed through the delivery line in the form of a viscous suspension Pressure injected into the annular gap 22.
  • the suspension consists of cement type CEM I 42.5, a Water content of 35%, based on the cement and one 3% plasticizer (plasticizer here: melamine sulfonate), based on the cement content.
  • Figure 3 is an approximately 50% degree of filling of the annular gap 22 identified by line 36.
  • a steel plate is made 38 (shown in dashed lines in Figure 3) on the upper Welded end of the outer tube 10.
  • the arrangement is then rotated through 180 ° (FIG. 4). at The container lid 14 can then be used as required other steel cover 40 to be replaced.
  • the openings 30 on the finished container also closed.
  • the 7-day compressive strength according to DIN 1048, part 2 of the heavy concrete is 26 N / mm 2 , the corresponding 28-day compressive strength is 46 N / mm 2 .
  • the modulus of elasticity of the concrete was determined based on DIN 1048 Part 5 with 30,000 N / mm 2 .
