Description of the Related Art In a targin building, a turbine, which is generally a prime mover, a generator that is driven by the turbine to convert the shaft power generated by the turbine into electricity, a condenser that returns the steam that has been used by the turbine to water, and steam Turbine accessories such as pumps and lubricating oil devices that make up the cycle are installed. Further, the auxiliary generators such as the stator cooling water device and the sealing oil control device necessary for the operation of the generator, the main circuit cooling device, the exciter, and the neutral point grounding device are also installed in the turbine building.

切りは設けられていない。The generator is installed on a generator base integrated with the turbine base, and this installation level is called the operation floor. A turbine is also installed on the operation floor, and a partition is provided between the turbine and generator because the operation floor is a place for temporary deployment of turbine parts during regular inspections and repairs. Has not been done.

内に落し込める様開口が設けられている。FIG. 3 is a sectional view showing a structure around a generator base in a turbine building of a conventional boiling water nuclear power plant. The lower half of the generator 2 is placed on the generator base 1 in order to align the shaft centers of the generator 2 and the turbine 3 with the generator base 1.
There is an opening that can be dropped inside.

線管理区分となっている。A decorative plate 4 is placed around the generator 2 so as to close the opening for safety and aesthetic reasons. However, the decorative plate 4 is that the generator 2 is constantly vibrating, and the bearing bracket 5 has a large number of ribs for reinforcement and has a complicated shape, so there is a gap between the decorative plate 4 and the decorative plate 4. Because of this, it is not designed to seal the opening. Therefore, the area under the generator is not separated from the operation floor, and has the same radiation control division as the operation floor.

性廃棄物として処理しなければならない。The operation floor of the turbine building of a boiling water nuclear power plant is that the steam having radioactivity generated in the nuclear reactor is directly introduced into the turbine to generate power, which causes radiation. It is a controlled area.
In the radiation controlled area, access to the area is controlled and work hours within the area are limited. In addition, waste materials from the area must be treated as radioactive waste.

めに放易線管理区域となってしまう不合理がある。On the other hand, since electrical equipment such as generator auxiliary equipment, main circuit cooling device, exciter, neutral point grounding device, etc. does not contain radioactivity in itself, these devices are installed under the generator. Although the area is originally good as an uncontrolled area, the operation floor and the area under the generator are not completely separated because of the vibration and the complexity of the shape of the boundary at the opening of the generator base as described above. There is an absurdity that it becomes an easy line control area.

とする。Since the present invention separates the operation floor of the turbine building from the area under the generator, it provides a building structure having a simple shape of boundary that does not cause vibrational problems and can be reliably separated. The objective is to rationalize the radiation control of and reduce the amount of radioactive waste generated.

ウンダリを形成することができる。Since the main circuit terminal box 7 and the neutral side terminal box 8 have a holding structure that is vibrationally insulated from the generator 2,
The generator main circuit 9 and the neutral point circuit 10 are less susceptible to the vibration of the generator 2. The sealing plate 11 is welded all around the bus duct jacket of the generator main circuit 9 or the neutral point circuit 10. Since this seal plate 11 is also less susceptible to the vibration of the generator 2, it can be fixed to the structure of the turbine building, etc., and integrated with the building structure, the operation floor of the turbine building and the area under the generator. It is possible to form a boundary that separates

ール性を得る事ができる。1 shows an example of the structure of a turbine building according to the present invention. Although not particularly shown in FIG. 1, the main circuit terminal box 7 and the neutral point terminal box 8 are hung from a terminal of the generator 2 through a flexible material such as rubber, or the power generation is performed. Since it is directly supported by the machine base 1, it is less susceptible to the vibration of the generator 2. The generator main circuit 9 connects the main circuit terminal box 7 and the main transformer (not shown in FIG. 1), and the neutral point circuit 10 includes the neutral point side terminal box 8 and the neutral point grounding device. Each of them extends to the area under the generator to connect 15. A seal plate 11 is provided in a vertical portion of both circuits, and a boundary 12 is formed by providing the seal plate 11 and an intermediate floor at an intermediate level between the operation floor of the turbine building and the downstairs.
The generator main circuit 9 and the neutral point circuit 10 are cylindrical bus ducts, and since their outer covers are smooth arcs, a seal plate 11 is attached and the tangent lines are welded all around to provide high sealing performance. You can get it.

台として使用することができる。With the above-mentioned structure, a boundary shape capable of reliably performing sealing can be obtained without being affected by the vibration of the generator, so that the operation floor of the turbine building and the area under the generator can be completely separated. It becomes possible. In addition, the intermediate floor provided here as a boundary has appropriate strength so that the bearing bracket can be disassembled when inspecting the terminal box and bushing current transformer under the generator and pulling out the rotor of the generator. It can be used as a mount.

点検、補修作業の効率を高める事が可能となる。According to the present invention, the area under the generator is separated from the operation floor in terms of the radiation control section, and can be a non-control area. By becoming an unmanaged area,
It is installed in this area. When accessing electrical components such as generator auxiliary equipment, main circuit cooling device exciter, neutral point grounding device, etc., there are no restrictions on entry / exit control and work time, which are indispensable in the conventional building structure.
