Definitions

  • the invention relates to a power plant with a reactor building and with separate structures for components and auxiliary systems.
  • Such a power plant is known (US-A-4 304 633).
  • the individual buildings are arranged one behind the other.
  • the turbine building is oriented in such a way that if a turbine blade breaks, the reactor is not hit by fragments.
  • Such a building arrangement alone does not provide protection against earthquake stress.
  • the invention has for its object to design a power plant that is less sensitive to earthquake stress than known systems and is therefore better suited to be installed in seismic zones.
  • the aim should be for the individual buildings to perform the slightest possible turning and tilting movements if the subsurface is assumed to be warped in the horizontal and vertical directions. At the same time, the additional effort required for this should be kept as low as possible.
  • each separate building largely corresponds to the footprint of the reactor building and that one or more power plant components or auxiliary systems are arranged in a separate building.
  • This solution avoids building units that are too small. It is based on the knowledge that the larger its base area at the same height, the smaller the swiveling movement that the building performs due to the earthquake acceleration. On the other hand, this type of construction also avoids buildings that are too large, which would require extremely strong and complex foundation slabs. The number of pipe and cable ducts connecting the individual buildings is also reduced.
  • Building floor areas according to the invention can be achieved, for example, by accommodating, for example, a power generator and a switchgear in a common building. This building is then the same size as the separate buildings for the reactor and for the turbogenerator. By combining two or more components in a building, the advantage is achieved that the base areas of the buildings are optimally used.
  • a particularly advantageous solution is obtained if, in a further development of the invention, when using a plurality of emergency power generators, these are accommodated in the common building in rooms adjoining two opposite fronts of the building and the switchgear assemblies are arranged in the rooms in between.
  • the common building for the emergency power generators and switchgear when the power plant is expanded by a second power plant block, the common building for the emergency power generators and switchgear can be expanded in an identical manner, i.e. be doubled.
  • the result is that the emergency power generators are assembled, disassembled and supplied with fresh air and cooling air in the shortest possible way even after doubling over the outer wall.
  • a particularly expedient construction results when the common building in the embodiment of the invention faces the reactor building with a front that is perpendicular to those front sides on which the rooms for the emergency power generators directly adjoin. With this orientation of the building described, the connection to the building for the steam generators requires much shorter cable lengths than in any other building orientation.
  • the central reactor building 2 has a circular floor plan. In addition to the nuclear reactor, it contains several heat exchangers for the secondary circuit (not shown). It also includes a variety of
  • a reactor auxiliary plant building 3 nestles directly on the reactor building 2.
  • the turbogenerator 4 is installed next to the reactor building 2 in a separate building, the machine house 5.
  • a switchgear building 6 is attached to the reactor auxiliary plant building 3. Behind the switchgear building 6 there is another small separate building 7, in which essentially four emergency power generators (not shown) are accommodated.
  • an emergency feed building 8 can still be seen at some distance from the reactor building 2. This contains several emergency feed devices (not shown). These buildings are connected to each other with channels 9 to 22, which accommodate the various pipes and electrical cables. The connections of the generator to the consumer network are omitted here for the sake of clarity.
  • Such a power plant 1 is sensitive to larger ground displacements or faults, such as could occur in areas prone to earthquakes.
  • FIG. 2 shows a nuclear power plant 23 according to the invention, in which only three buildings of approximately the same size are used per power plant block. These are the reactor building 24 with the nuclear reactor and the heat exchangers (not shown) for the secondary circuit, the building 25 for the turbogenerator 26 and a third one, the emergency power generators 27, 28, 29, 30, the associated switch positions 31, 32, 33, 34 and building 35 housing the emergency feed devices (not shown).
  • the reactor building 24 with the nuclear reactor and the heat exchangers (not shown) for the secondary circuit
  • the building 25 for the turbogenerator 26 and a third one
  • the emergency power generators 27, 28, 29, 30, the associated switch positions 31, 32, 33, 34 and building 35 housing the emergency feed devices (not shown).
  • All three buildings 24, 25, 35 shown in FIG. 2 maintain a safety distance from one another. As a result, there is a certain freedom of movement, which enables the pipe and cable connections laid in the ducts between the individual buildings to elastically absorb minor displacements between the buildings.
  • This nuclear power plant 23 shown in FIG. 2 can be doubled in terms of its electrical power, as indicated by dashed lines, by a second power plant block 39.
  • the emergency power generator, emergency feed and switchgear building 35, 40 assigned to the two power plant blocks are put together in mirror image or are combined from the outset in a correspondingly large building.
  • FIG. 3 shows a further development of the power plant 23, 39 of FIG. 2. While the reactor building 41 and the building 42 for the turbogenerator 43 are unchanged, the internal structure of the building 44 is for the emergency power generators 45, 46, 47, 48, Emergency feed devices and switchgear 49, 50, 51, 52 can be changed.
  • the four emergency power generators 45 to 48 and emergency feed devices are housed in pairs along opposing outer walls 53, 54 of this building and the associated switchgear in the rooms between the emergency power generators.
  • the building 44 is arranged in relation to the reactor building 41 such that that end face 55 of the building 44, which is located between two outer walls 53, 54 adjacent to the emergency power generators and emergency feeding devices, faces the reactor building 41.
  • the pipelines and the cable connections between the two buildings are similarly short to those of the exemplary embodiment in FIG. 2.
  • the two power plant control rooms can also be arranged and, if necessary, combined into one room area.
  • all emergency generators and emergency supply systems remain with this version in the case of the power plant, which consists of two power plant blocks, is accessible from the outside, which facilitates assembly and disassembly.
