していることである。At nuclear power plants, flammable materials handling rooms that handle a large amount of combustible materials such as fuel oil and lubricating oil are subject to two laws. 1
One is the Building Standards Act, and the other is the Fire Service Act. According to the Building Standards Act, the combustible material handling room of a nuclear power plant must be divided into a fireproof division as a mixed-use division, so the walls that separate it must be fireproof and have a structure with no openings. Additionally, doors installed in fireproof walls must be Class A fire doors with automatic closing devices. Here, even if the door is pushed open, it will automatically close when the pushing force is removed to prevent flames and smoke from flowing in or out. What is a structure without openings?
If ventilation and air conditioning ducts penetrate a fireproof wall that serves as a fireproof compartment, a damper with fireproof performance that automatically closes in the event of a fire must be installed, and if the duct or piping penetrates a fireproof wall that serves as a fireproof compartment. If so, the through-holes must be treated with fireproofing.

２を放出・充満させ窒息消火を行なうものである。According to standards under the Fire Service Act, it is mandatory to install carbon dioxide fire extinguishing equipment in combustible materials handling rooms, that is, in hazardous materials facilities. Carbon dioxide fire extinguishing equipment is a carbon dioxide storage container connected to piping filled with compressed and liquefied carbon dioxide, and in the event of a fire, the valve of this storage container is opened to allow Co2 to flow into the piping. CO2 is released into the combustible material handling room from the sabo and the injection head installed at the end or midway of the piping.
2 is released and filled to extinguish the fire by suffocation.

は、気密処理を行ない、また可燃物取扱室の扉は気密構
造としなければならない。When operating the carbon dioxide fire extinguishing equipment and releasing CO2 into the combustible materials handling room, the ventilation system in the room must be stopped according to fire regulations, so a ventilation air conditioning system that penetrates the fireproof wall of the combustible materials handling room is required. The duct is connected to the operation of the carbon dioxide fire extinguishing equipment [! One chain of dampers is provided, and carbon dioxide is released after the dampers are opened. In addition, according to fire regulations, rooms that handle combustible materials that emit CO2 must be constructed as airtight as possible.
The through-holes of the ducts and piping installed through the combustible material handling room must be airtight, and the door of the combustible material handling room must be airtight.
以上の施策を行なうことにより、ＣＯ２を放出する際に
は可燃物取扱室内の雰囲気を外部から遮断することが可

用ダクトがその耐火壁を貫通する部分に気密シールを施
している。In the conventional building structure of an atomic saw power plant, in order to increase the fire extinguishing effect of CO2, it is also necessary to avoid man-made disasters due to C○2 drifting into passageways other than the combustible materials handling room where CO2 is released, and waste of CO2 for fire extinguishing. To prevent the thickness from 30α to 250
M4 fireproof walls made of CRG reinforced concrete walls, floors, and ceilings have been added, and the areas where piping, electrical conduits, and ventilation/air conditioning ducts penetrate the fireproof walls are airtightly sealed.

扱室が外部と気密構造となるようにしている。Furthermore, the entrance/exit door of the combustible material handling room that releases CO2 has a semi-airtight structure, and the intake/exhaust port of the ventilation air conditioning duct is equipped with a damper that automatically closes when CO2 is released. This ensures that the combustible material handling room is airtight from the outside in the event of a fire.
しかし、火災発生時にＣｏ２を放出する可燃物取扱室を
気密状態としてＣＯ２を放出した場合、放出以前に大気

響を及ぼす可能性がある。In this case, assuming that the combustible material handling room that releases CO2 is completely airtight, the indoor pressure after releasing CO2 is approximately 1
, 43 Nf/ciats, resulting in a pressure that exceeds the strength of the fireproof walls and u-tools. However, since there is some leakage from the airtight seals, doors, and damper parts, it is thought that the indoor pressure will not reach the above-mentioned indoor pressure. High pressure may have an adverse effect.

ンパにしている。An air supply fan 12 provided for ventilation and air conditioning of the nuclear power plant building 1 supplies outdoor air to an air supply suction duct 13.
Air is sucked in from the air and supplied to the inside of the nuclear power plant building 1 through the air supply discharge duct 14. The exhaust fan 15 sucks air inside the nuclear power plant building 1 through an exhaust suction duct 16 and exhausts it to the outside of the nuclear power plant building 1 through an exhaust discharge duct 17. Among the ducts installed for ventilation and air conditioning of the nuclear power plant building 1, the fireproof wall 7 of the combustible materials handling room 3 is passed through, and the ducts are installed in both this combustible materials handling room 3 and other rooms inside the nuclear power plant building 1. A damper 19 is installed in the duct 18 for supplying and exhausting water to and from the duct 18. The damper 19 has fire prevention performance and a V1 function that automatically closes in the event of a fire. This is because if there is a combustible material handling room 3 inside the nuclear power plant building 1, it is necessary to form a fire prevention section as a different type of use section according to the provisions of the Building Standards Act. As mentioned above, the walls 4, floor 5, and ceiling 6 of the handling room 3 are made of a frame consisting of a fireproof wall 7 structure, and the duct 8 that penetrates this fireproof wall 7 has a fire prevention function and automatically shuts down in the event of a fire. This is based on the fact that it is obligatory to install a damper 19 that has the ability to shut down. Furthermore, the carbon dioxide fire extinguishing equipment 18 is activated in a duct 18 that penetrates the wall 4, floor 5, and ceiling 6 surrounding the room to be protected by the carbon dioxide fire extinguishing equipment 8, that is, the combustible materials handling room 3, according to the provisions of the fire service regulations. This is based on the fact that it is necessary to provide a damper 19 with a function of automatically closing when CO2 is released into the combustible material handling room 3. From the standpoint of simplicity, this damper 19 is a C02 fire damper.

な圧力が作用せず悪影響を防ぐことが可能となる。If a fire breaks out in the combustible material handling room 3 that handles a large amount of combustible material, the valve of the carbon dioxide storage container 9 is opened. The CO2 flowing out from the carbon dioxide storage container 9 is transferred into the combustible material handling chamber 3 through the pipe 10 and is emitted from the injection head 11. At the same time, CO2 flowing through the pipe 10 is supplied to the damper 19, and the pressure of the CO2 closes the damper 19, thereby stopping ventilation in the combustible material handling chamber 3. The CO2 emitted from the injection head 11 fills the combustible material handling room 3 while pushing the air existing in the combustible material handling room 3 out of the nuclear power plant building 1 through the fire-resistant pressure relief duct 21. , reduce the depth of M and perform nitrogen extinguishing. By releasing the air in the combustible material handling room 3 from the pressure relief duct 21 to the outdoors of the nuclear power plant building 1, an increase in the indoor pressure in the combustible material handling room 3 can be prevented. Excessive pressure does not act on the nuclear power plant building 1, making it possible to prevent adverse effects.
