Definitions

  • the invention relates to a building made of concrete walls, in particular for nuclear plants, which include plant components as protection against external influences.
  • the concrete walls usually consist of reinforced concrete and are designed, at least in the areas that fulfill protective functions, in such a way that they can withstand the underlying external influences, e.g. can withstand a plane crash.
  • the so-called secondary shielding of a nuclear power plant e.g. is designed for this purpose in the form of a concrete cover up to 2 m thick.
  • the concrete is of course reinforced.
  • the invention is based on the task of minimizing the vibrations that are to be expected in the event of an impulse-like load (special case of an aircraft crash). As a consequence, higher security of components and systems against external influences can then be obtained with comparable effort.
  • the concrete walls of the building are formed in two layers in the area of exposed areas and form a cavity which may be filled with a damping material.
  • the cavity can also be provided with an additional thin-walled lining.
  • the invention also reduces the need to provide costly functional evidence for components and buildings that is stressed by shock-induced vibrations. This applies in particular to all electrical and I&C components.
  • the functionality of these systems has so far been proven for a frequency range up to approx. 35 Hz, as is to be expected in earthquakes, for example.
  • the present requirement to prove the functionality even at high acceleration values in the frequency range up to 80 Hz, as appears to be possible in particular in the event of an aircraft crash, is largely made superfluous by the above-mentioned reduction in accelerations.
  • the outer contours of the two-layer wall areas can advantageously protrude beyond adjacent wall areas. This enables more extensive protection.
  • this construction method offers the possibility of maintaining the interior of the building as a whole despite the two-layer construction, which is therefore thicker.
  • the two-layer wall areas can advantageously be provided at the corners of the building. You can round off the corners there so that the load-bearing behavior of the shells can be used to increase the energy disposition.
  • the outer layer of the two-layer wall areas can advantageously consist of steel fiber concrete with appropriate reinforcement. In this way, a tough, energy-absorbing, flexible structure can be achieved, which allows the plastic behavior of the steel fiber concrete and the damping effect of the lined cavity to be fully exploited.
  • the thickness of the cavity can be chosen approximately equal to the thickness of the outer plasticizing shell. However, it can also be optimized and determined by the filling material.
  • a two-layer wall area is designed as a prefabricated component and is attached to the outside of a solid concrete wall.
  • attach means that the prefabricated components have the necessary stability during normal operation. This can e.g. already be given by the weight with which the wall elements rest on the top of a concrete wall.
  • the reactor building 1 of a pressurized water reactor shown in FIG. 1 surrounds a steel safety container 2 in the form of a sphere with e.g. 50 m diameter.
  • the ball 2 is enclosed at its upper area by a hemispherical roof section 3 of the reactor building 1.
  • the reactor building is guided as a vertical cylinder 4 to the base plate 5 of the reactor building, which is embedded in the ground 6.
  • the thickness D of the reactor building wall 3, 4 amounts to e.g. 2 m. This ensures that aircraft crashing into the reactor building 1 cannot cause serious destruction, which could lead to the safety container 2 including the radioactive parts being opened, for example.
  • a so-called armature chamber 10 is connected to the outer wall 4 of the reactor building 1 and comprises armatures for shutting off the live steam lines leading from the safety container 2. Since these fittings have to be protected from destruction, the walls 11 of the fitting chamber 10 are, for example, one
  • the cuboid shape is at least as thick as that of the reactor building 1. In a typical rectangular building, for example the emergency feed building of a reactor system, the edges and corners represent the exposed impact areas analogously to the armature chamber.
  • the upper, outer corner 12 of the armature chamber 10 is formed in two layers in the region 14.
  • an outer shell 16 runs parallel to an inner shell 15, which corresponds approximately to the shape of the original wall 11 with half the wall thickness, at a distance from the thickness of the layer 15, so that a cavity 17 is formed.
  • the outer shell 16 consists of a concrete reinforced with steel fibers. It is quasi homogeneously compliant. Its outside 18 protrudes, as can be clearly seen in FIG. 1, by about half the original wall thickness, that is to say about 1 m above the wall plane 19.
  • the cavity 17 is formed in three parts because it is divided by two supports 20 and 21. Rigid foam is accommodated in the cavity 17 as a filling material with a damping effect. It is thus achieved in the exposed wall area of the corner 12 that, when exposed to external loads, forces are only weakened into the armature chamber 10 and are transmitted therefrom into the reactor building 1.
  • corner 12 is again provided with a two-layer wall area 14.
  • the outer shell 16 is supported here only by a single support 23, so that a cavity 17 is formed with two chambers. It contains metal wire bodies as a damping filler.
  • the cavities 17 can also be ordered by means of prefabricated thin-walled shaped bodies without filling with steaming material.
  • the inner shell 15 of the two-layer wall area 14 is made with practically the same wall thickness as the wall 11 is, however, with an outer rounding 24. Above it rises the outer shell 16, which this time is designed without an inner support, so that a single-chamber space 17 is formed.
  • the reactor building 1 is formed in two layers in the area 25 of a roof 26, which forms a corner 27.
  • the inner shell 28 of the two-layer region 25 is here reduced to half the original thickness of the solid walls 29.
  • the outer shell 30 runs with a parallel curve in the alignment of the outside of the walls 29.
  • the cavity 31 is in turn filled with a damping material. Despite the "weakening" of the wall in area 25, there is sufficient resistance to external penetration. In addition, it is achieved that external forces which can act on the exposed corner 27 are reduced and thus only trigger lower acceleration forces in the interior of the reactor building 1.
  • the reactor building 1 is shown in the area 35 at the level of an inner ceiling 36 on which components 37 are supported.
  • the blanket 36 closes e.g. a room 38 with electrical systems, which are indicated by cable routes 39.
  • the outer shell 40 of the two-layer region 35 is rounded, so that it rises as a curvature over the surface of the reactor building 1.
  • the intermediate space 41 in turn contains a filling material.
  • the reactor building 1 in an area 50 in the vicinity of the ceiling 36 can also be constructed in two layers over a greater height. This not only protects the ceiling 36, but also the ceiling 51 underneath.
  • the outer shell 52 made of fiber concrete forms with the inner shell 53 made of reinforced concrete two adjoining cavities 54 and 55, which contain an insulating material.
  • the intermediate support 56 is dimensioned so that with immediate on No significant forces are transmitted from the outside, since the inner shell 53 has greater flexibility when the load is applied.
  • the reactor building 1 is protected in the area of a corner 60 and an underlying load-bearing ceiling 61 by prefabricated components.
  • the component 63 assigned to the corner 60 has a structure which is adapted to the corner and is rectangular in cross section.
  • the two layers 64 and 65 consist equally of steel fiber concrete with great toughness.
  • the cavity 66 contains a filler material.
  • the component 63 sits sufficiently firmly on the reactor building 1 solely because of its weight. It forms an insulating protective layer there, which reduces the introduction of impact loads into the building 1 at the exposed point in the event of external influences.
  • the component assigned to the ceiling 61 covers the attachment of the ceiling 61 to the vertical concrete wall 71. There it is let into a corresponding recess 73 with a dovetail-like extension 72.
  • the gap 75 present after insertion can be filled in to increase the strength in order to achieve a form-fitting hold of the component 70.
  • other attachments of the components 63, 70 to the reactor building 1 are also conceivable.
