Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a reactor building of a nuclear power plant, and particularly to a reactor building characterized by the arrangement of a central control room 21I.

[Technical background of the invention and its problems]

The nuclear power plant has a nuclear reactor containment vessel (PCV) installed at the atomic 'F5k1m' and a turbine 111m installed at the power generation turbine.

The reactor house is constructed to surround the outer periphery of the reactor building, in which the PCv is installed, and the central control room is located in the space formed between the reactor building and the reactor building. ,a
It consists of a square complex building in which a calculation room, an air conditioning machine room, etc. are located.

Conventionally, this reactor building, as shown in its plan view in FIG.
A PCV 64 is installed approximately in the center of the reactor building 61.

In the conventional reactor building 60 having such a configuration, the central control room 70 is connected to the reactor building 61 and the square complex building 6.
It is located approximately in the center of the space formed between 3 and 3. This is because the bench board 71, upright board, baggage-type control υ11 board, etc. arranged in the central part ff1l to 70 require a somewhat large arrangement area due to the required arrangement length, and especially the bench 5HH71. Since it cannot be divided or modified due to the requirements of operability and system classification, the main arrangement conditions for the central 1i!I fil chamber 70 have been determined.

In this way, in the conventional reactor building 60, the central part 1311 chamber 70 is located approximately in the center of the space formed between the atomic short wire 61 and the square composite building 63, so that this central control The building span (building column core span) fJ of the part where the room 70 is arranged is larger than the other parts.

For this reason, the reactor building 60 becomes larger and 11
The number of pipes, cable trays, cable conduits, air conditioning ducts, etc. installed indoors has increased, causing longer construction work and increased construction costs.

[Purpose of the invention]

The present invention has been made with these points in mind,
Minimizing the area of the building to the necessary minimum 12, reducing the construction cost of the building, and reducing the various types of equipment installed within the building. I! The purpose of this project is to provide reactor buildings for nuclear power plants that reduce the amount of materials used.

[Invention II! dog) The present invention provides an atomic short wire in which a PCV is arranged,
A reactor building consisting of a rectangular composite building that is configured to take the outer circumference of this short atomic wire and have a central control room located between the short atomic wires, and the central control room is located between the square composite building and the central control room. It is characterized by being placed in the corner of the

According to the present invention, by effectively utilizing the corners of the square complex building, the span of the building in which the central control room is located can be reduced, and the area of the building can be reduced to the necessary limit.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are a plan sectional view and a vertical sectional view, not showing one embodiment of a nuclear reactor building according to the present invention. In the figure, reference numeral 11 is a cylindrical atomic short wire, which has a circular cross section, and a PCV (reactor containment vessel) 14 is disposed inside. A square composite building 13 is arranged so as to surround the outer periphery of this cylindrical short atomic wire 11, forming an open reactor building 10.

Of the space formed between the cylindrical atomic short wire 11 and the square composite building 13, one of the corners has a center R
An i control room 20 is arranged. In this central control history 20, there is a bench board 21 where operators constantly monitor the operating status of the reactor and issue necessary commands. aa <Upright board>
22 are arranged. Further, a terminal board 23 is arranged beside the control 1A22. Code 24 is control? It is a computer room located near A22.

As described above, in this embodiment, the central control room 20 is a square complex i! Since the main control room 20 is located in the corner space formed between the main control room 20 and the cylindrical atomic short wire 11, the building span (building column core span) L of the part where the central control room 20 is located is different from the conventional layout. Building span by method 1 (6th
(see figure). This makes it possible to reduce the installation surface and area of the reactor building 10, reduce building construction costs, and shorten the construction work.
It is possible to reduce the amount of piping, cable trays, cable conduits, air conditioning ducts, etc. and the amount of components required for tangles installed inside the building.

For example, in a 1100 MWe class 12 type 1112 water type nuclear power plant, conventionally the building span layer was 16711 mm.
'2 and the installation area of 63 square complex buildings is 83 TIL
X 83 m, whereas in this example,
Only the building span needs to be 11.45+rL, and the installation area of the square composite building 13 is 72', 9m x 72.9711, which is a reduction of 111, which is about 25%, in the reactor building volume.

and a plurality of turbine buildings 30 (for example, two).
The layout when placed is shown.

In Fig. 3, the reactor building 10 and the turbine f building 30 are arranged in an L-shape, and the next Y) is the nuclear detached house 1'l-
100 and the turbine building 30a are arranged adjacent to this. As is clear from FIG. 3, the central control room 20 for each preceding month and the central control room 20a for the next month can be connected, which can improve operational efficiency and facilitate maintenance and management. can.

Figure 4 shows reactor building 1o and turbine building 30 by preceding month.
and the next issue show an example in which the reactor building 10a and the turbine building 30a are arranged in a square shape. In this embodiment as well, the central control room 20 of each preceding machine and the central control room 20a of the next machine can be interconnected.

FIG. 5 is a plan sectional view showing another embodiment of the present invention. In this embodiment, the atomic short lines 41 are hexagonal (1°1

A central control room 50 is arranged in one of the corners of the composite building 43 in the space formed between the short atomic wire 41 and the composite building 43 .

In this example as well, the building facility area is f1δ
Reduce, li! It is possible to reduce construction costs and shorten construction work hours.

J3, the same effect can be obtained even if the atomic short line is a polygon other than a hexagon.

〔Effect of the invention〕

As explained above, according to the present invention, the installation area of the reactor building is reduced by 11δ, and tL! It is possible to reduce construction costs and shorten the construction period. Additionally, various communication members disposed within the building can be reduced. moreover,
