Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house in which a worker can take in and excrete drinking water in a radiation controlled area such as a nuclear facility.

[0002]

2. Description of the Related Art Conventionally, in radiation control areas (including radiation and pollution areas) such as nuclear facilities,
There is a possibility that the radioactive substance may be taken into the body from the mouth of the worker via tools, clothes, etc. that are contaminated with the radioactive substance. Therefore, drinking water is prohibited in the controlled area, and the worker must once exit from the controlled area in order to drink water, and at that time, the radioactive material outside the radiation controlled area must be removed. Since it was necessary to take measures to prevent the spread, it was troublesome and time-consuming for the work to leave and enter the area. The same applies when leaving / entering the area for excretion.

[0003]

In order to solve such a problem, if a shed for drinking water (house) is installed at a main place in the radiation controlled area, the above-mentioned troubles for leaving and entering the area. It is very convenient for the operator as it does not require any special work. However, in order to drink water at the place where drinking water is installed in the house, before the worker reaches the place where the drinking water is installed, various measures such as removal of pollution and other various measures are taken to prevent radioactive substances from being ingested into the body from the worker's mouth. Measures need to be taken.

Similarly, if a facility for excretion is also provided, it will be very convenient for the operator. In the case of excretion, it is extremely unlikely that the radioactive substance will be ingested into the worker's body, so it is sufficient to remove the gloves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The specific structure of the present invention will be described below in detail with reference to the accompanying drawings. 1 is a partially cutaway perspective view showing the structure of the present invention, FIG. 2 is a cross-sectional view showing the structure of the panel of the present invention, and FIG. 3 is a perspective view showing the case where the excrement house is adjacent to the house body.

In FIG. 1, reference numeral 1 is a main body of a house constituted by a panel 8, the interior of which is separated into a pollution inspection place 2 and a drinking place 3. Reference numeral 4 denotes a ventilation air-conditioning facility installed in the drinking place 3, which is composed of a filter and a blower. 5 is a ventilation port of the ventilation and air conditioning equipment, and 6 is a drinking water stocker. Further, a monitor camera 7 for monitoring the inside of the house is installed at an appropriate location of the house body 1. On the other hand, the pollution inspection place 2 is provided with a pollution inspection device 13, a voice transmission device 14, and the like. Reference numeral 10 is an entrance door provided in the house body 1, 11 is a damper provided in the door 10, 12 is an air escape hole, and 15 is a caster provided in the lower part of the house body 1. Further, in FIG. 2, numeral 9 is a radiation shielding material provided between the inner and outer panels 8 and made of a material such as lead or iron.
Further, in FIG. 3, reference numeral 16 denotes an excrement house, which is installed adjacent to the house body 1 and is constituted by a panel 19. Reference numeral 17 is an entrance door of the excrement house 16, and 18 is an odor exhaust pipe.

Since the present invention has such a structure, the house body 1 is installed in the radiation control area, the ventilation air conditioning equipment 4 is operated to clean and purify the air outside the house body 1, and the air is blown from the blower port 5. It is supplied into the house body 1, passes through the drinking place 3 and the contamination inspection place 2, and is discharged out of the house body 1 through the damper 11 and the air escape hole 12 provided in the entrance door 10. At this time, the atmospheric pressure inside the house body 1 is
It is set to be higher than the atmospheric pressure in the controlled area where is installed. Therefore, the house body 1 is always filled with clean and purified air, and even if the radioactive substance diffuses into the controlled area for some reason, the air inside the house body 1 is not contaminated.

Therefore, when an operator working in the controlled area drinks water, the entrance door 10 of the house body 1 is opened,
First, after entering the contamination inspection place 2 and closing the entrance door 10, the contamination inspection device 13 conducts an own contamination inspection over the whole body to confirm the presence or absence of contamination adhesion.

At this time, if necessary, the monitor camera 7
Also, by using the voice transmission device 14, it is possible to confirm and instruct the contamination inspection to the worker from a remote place outside the controlled area or inside the controlled area.

Then, if it is confirmed that the radioactive substance is not attached to the surface of the worker's body, the worker is allowed to enter the drinking place 3
The drinking water stored in the drinking water stocker 6 can be drunk.

After drinking, the worker can return to the controlled area via the contamination inspection place 2. In this case, the contamination inspection can be omitted.

In addition, when the worker uses the feces, the excretory equipment (not shown) installed in the main body house 1 does not have to be a special excretory equipment,
It may be provided in a commonly used prefab assembly office or the like. ) Or as shown in FIG. 3, the entrance door 17 of the excretory house 16 adjacent to the main body house 1 can be opened to enter the room.

It should be noted that the excrement facility or excrement house 16 in the main body house 1 according to the present invention does not necessarily have to be in a position to be used after passing through the contamination inspection device 13.
There is no problem in controlling contamination of workers even if they are directly inserted from the control area. Therefore, it can be appropriately changed depending on the conditions of the installation place.

The excrement facility or excrement house 16 installed in the controlled area as described above preferably has a function of incinerating excrement on the spot. With such a configuration, it is low cost and easy to move because no additional work or equipment such as piping installation for water and sewage, sewage purification equipment, etc. is required.

Further, as shown in FIG. 2, between the panels 8 forming the inner wall and the outer wall including the ceiling of the house body 1,
If the radiation shielding material 9 made of a material such as lead or iron is inserted as necessary or inserted in advance, it can be safely used even if the house body 1 is installed in a place with a high radiation dose. . The same applies to the excretory house 16.

When it is necessary to move the installation place of the house of the present invention to the work in the control area, the work is performed by the casters 15 provided under the house body 1 and the excrement house 16. It can be easily moved to a place that does not interfere with the operation.

[0018]

As described above, according to the present invention, since the house body is provided with a measure for preventing the intrusion of radioactive materials, the house can be installed in a radiation control area and workers in the area can drink water. In addition, since excretion equipment is installed as necessary to enable convenient use, it is possible to perform continuous work for a long time within the radiation control area, and as a result, save time and labor required for exiting and entering the area. Therefore, it is possible to improve work efficiency.

In addition, the present invention has the same conditions as a workplace in a general environment in terms of hydration and excretion in addition to this, and is suitable from the viewpoint of public acceptance of work in a controlled area centering on a nuclear facility. .

Further, the present invention is extremely effective in that it can be easily moved as required.
