Definitions
- the invention relates to a technical system with a number of system components each supported by a number of supports and with a number of pressure-carrying lines. It relates in particular to a nuclear power plant.
- pressure-carrying lines can be used, for example for guiding a flow medium.
- the design pressure of the flow medium carried in such lines can be selected to be very high, so that mechanical failure of the lines or individual line elements can result in considerable mechanical stress on the immediate surroundings of the respective lines.
- the pressure-carrying lines can in particular be provided with so-called failure fixed points, so that in the event of a mechanical failure, at least the location and the immediate vicinity of an accident can be planned and thus controlled.
- the invention is therefore based on the object of specifying a technical installation of the type mentioned above, which is also particularly protected against further damage to system components in the event of a mechanical break in a pressure-carrying line.
- At least one of the supports is segmented in a hit area expected in the event of a pipe break in a pressure-carrying line.
- the invention is based on the consideration that the total damage to be expected in the event of a pipe break in a pressurized line can be kept particularly low by preventing the transmission of the forces and deformations of system components transmitted to the system system to other system components in the event of a pipe break.
- a particularly suitable starting point for such a prevention of the transmission of forces introduced are supports used to support the system components, such as steel supports.
- supports used to support the system components such as steel supports.
- the impact of a pipe end that has become free on such a carrier can lead to the deformation of the system component supported as a whole, so that an undesired transmission of the forces and forced paths into other components such as, for example, pipelines or measuring lines, via this system component could go out.
- the carriers are at least in one, in particular by analyzing the possibly provided predetermined breaking points can be provided in such a way that the expected hit area can be designed in such a way that individual system parts can be avoided instead of forwarding the forces introduced.
- the respective beams are segmented in the expected hit area in the manner of adapter pieces, so that, if necessary, individual segments can be knocked out of the pipe end that has become free without secondary effects on the adjacent segments or, for example, on the system component as a whole.
- connection points can be loaded with a maximum of a predetermined limit shear force. It can thus be achieved that in normal cases, that is to say without bursting or striking pipelines, the carrier as a whole still has a sufficient load-bearing capacity and can therefore be used in a functionally appropriate manner. If, however, the accident to be treated according to the design, namely a pipe break, occurs, which acts on the respective carrier with a line end that has become free, then, due to the design pressure of the entrained flow medium, forces acting on the respective segment in the connection points lead to shear forces, resulting in knocking out of the respective adapter piece or middle segment.
- the limit shear force provided for the maximum load is therefore expediently chosen below the shear force to be expected for such an accident in the connection points.
- a particularly simple mounting option for a segmented carrier structure of this type can be achieved by adjacent segments of the or each segmented carrier advantageously being connected to one another via screw connections.
- the connecting screws of the or each screw connection are advantageously guided in a number of elongated holes.
- the elongated holes provided in this way ensure, in particular, that in the event of a trigger there are sufficiently clear paths so that there is no significant influence on the running process or the connected systems.
- the functionality of the connection is expediently ensured by appropriately dimensioned screws with a corresponding shaft for the transmission of the transverse forces limited in this way.
- a targeted pre-tensioning of the construction in particular by means of spring washers, can expediently be provided if necessary.
- the segmented carriers provided according to the invention are used in a nuclear power plant.
- a nuclear power plant it can be provided that such non-safety-relevant system internals within the pressure vessel or the outer jacket of the nuclear power plant are provided with such carriers.
- an inspection or operating platform is designed as a system component supported by a number of such segmented carriers.
- a large number of measuring or test lines can be routed along the inspection or operating platforms usually provided in a nuclear power plant, which could also be torn off in the manner of secondary damage if the respective stage is destroyed. Protection of such lines is possible in a particularly effective manner in that the supports provided for supporting such platforms are segmented in the expected hit areas.
- the advantages achieved by the invention are, in particular, that the segmented design of supports for system components in the near or surrounding area of pressure-carrying lines ensures that the forces and paths that are released in this way are reliably forwarded even in the event of a line break with pipe ends becoming free is excluded.
- This segmented design of the supports ensures that the respective segment is simply knocked out of the support in the event of a hit, without any overall deformation of the system component supported by the supports corresponding secondary damage can be expected.
- the steel structure as a whole does not experience any significant plastic deformation that could influence the primary load-bearing capacity as a whole.
- Consequent breaks in the deflecting piping system are also avoided in a targeted manner, since a significant setback in the piping system is not to be expected when the exposed pipe ends hit the respective support. Due to the segmented design of the beams, special anchorages, special constructions or shock absorber elements can also be dispensed with, even if the system design meets high safety requirements, so that simple retrofitting options are available in particular.
- FIG. 1 shows a segmented carrier for a system component in a nuclear power plant
- FIG. 2 shows the carrier according to FIG. 1 in cross section
- Figure 3 shows the carrier of Figure 1 also in cross section
- Figure 4 shows the carrier of Figure 1 after the impact of a free
- the carrier 1 according to FIG. 1 is provided to support an operating or inspection platform (not shown in more detail) in a nuclear facility.
- an operating or inspection platform is arranged inside the reactor building in order to give the operating personnel the possibility of movement at the appropriate points if necessary.
- an operating or Inspection platform is usually also used for guiding and holding measuring or other operating lines arranged thereon.
- the carrier 1 is also arranged in the vicinity of pressure-carrying lines of the high-pressure system of the nuclear power plant. Therefore, in the event of a pipe break in the pressure-carrying system, so-called deflecting pipe ends could occur, which could act with considerable forces on components located in their surrounding area.
- the carrier 1 is specifically designed to consistently prevent the transmission of the forces and forced paths introduced into the service or inspection bridge and via this in further lines arranged thereon in the event of such a malfunction and thus secondary damage is particularly low, even if a pipe breaks in the pressure-carrying system of the nuclear power plant to keep.
- the carrier 1 is segmented and, viewed in its longitudinal direction, comprises a number of segments 2a, 2b, 2c arranged one behind the other and connected to one another at their connecting points.
- This segmented version of the carrier 1 is selected such that in the event of a pipe break in the pressure-carrying system, the middle segment 2b can be knocked out of its position between the segments 2a and 2c comparatively easily.
- the carrier 1 is thus designed in the manner of an evasive system, so that even when an exposed pipe end strikes the segment 2b, a transmission of forces into the segments 2a and 2c adjacent to it is avoided.
- Adjacent segments 2a, 2b, 2c of the segmented support 1 are connected to one another in such a way that the connection points can be loaded with a maximum of a predetermined limit shear force, which is selected below the shear force actually expected for such a pipe break.
- Adjacent segments 2a, 2b, 2c of the segmented carrier 1 are connected to one another via screw connections 4.
- the carrier 1 is shown in cross section in the area of its first segment 2a in FIG. 2 and in the area of its middle segment 2b in FIG.
- the end flanges 6 provided for establishing the connection between adjacent segments 2a, 2b, 2c are provided with elongated holes 8 for receiving the connecting screws of the screw connections 4.
- the elongated holes 8 are designed so open that they allow a comparatively unobstructed evasion movement of the middle segment 2b when an exposed pipe end hits in an expected evasion direction indicated by the arrow 10. For this purpose, as shown in FIG.
- the elongated holes 8 arranged in the end flange 6 of the first segment 2a are designed to be open with their rear end, as viewed in relation to the expected impact direction of the pipe end, in order thus to allow the screws to emerge freely in the evasive direction.
- the front elongated holes 8 of the connecting flange 6 of the middle segment 2b as viewed in relation to the expected direction of impact of the pipe end, are open, so that here, too, an unimpeded exit of the connecting screws guided therein when the free pipe end strikes is possible.
- FIG. 4 shows the final state which can be achieved by means of this segmented construction of the carrier 1 after an exposed pipe end has struck.
- the middle segment 2b of the support 1 is shifted relative to its adjacent segments 2a, 2c.
- the force introduced is thus converted into a displacement of the segment 2b without any forwarding of forces into the adjacent segments 2a, 2c or a deformation of the carrier 1 in its entirety and thus also of the system component or control bridge supported thereby.
