抑制効果の向上を図っている。<Prior Art> Several structures have already been proposed for this type of combustion suppression tank for storing leaked liquid metal. For example, JP-A-61
-176889 describes a combustion suppression tank having a structure as shown in FIG. That is, when the liquid metal, for example, the liquid sodium pipe 2 disposed on the upper floor of the building 1 in a fast reactor plant or the like is damaged and sodium leaks from the liquid metal, the leaked sodium is first provided on the upper floor 1a. Received on the floor liner 3. The floor liner 3 is provided with a communication pipe 4 penetrating the upper floor 1a toward the lower floor 1b of the building. The combustion suppressing plate 5 is provided on the lower floor 1b below the communication pipe 4. A combustion suppressing tank 6 having a top is installed. Leakage sodium received on the floor liner 3 of the upper floor 1a flows into the communication pipe 4 due to the gradient of the floor liner 3 and is collected and stored in the tank 6 on the lower floor. Since the supply of air is suppressed in the tank by the action of the combustion suppressing plate 5, the sodium in the tank is suppressed from burning and extinguished by suffocation. Also, the communication pipe 4
A small container 7 is arranged in the tank directly below, and the lower end of the communication pipe 4 is immersed in sodium 8 accumulated in the small container 7, and new air flows in through the communication pipe. To prevent the combustion of sodium in the tank 6 to be improved.

As shown in FIG. 5, this air inflow prevention means is provided with a valve body 9 provided with a balance weight 10 in a swingable manner at the lower end opening of the communication pipe 4, and normally, the valve body 9 is loaded by the weight of the balance weight 10. Is at a position to close the lower end opening of the communication pipe 4. When the leaked sodium flows down through the communicating pipe 4, the valve body 9 is pushed down by the weight of sodium,
Sodium is recovered in the tank 6, but immediately after that, the valve body 9
Again closes the lower end opening of the communication pipe 4.

破損させることにもなりかねない。<Problems to be Solved by the Invention> In the above-described conventional combustion suppressing tank 6, the tank top is closed by the combustion suppressing plate 5 and a new air is prevented from flowing through the communication pipe 4. However,
Sodium flowing in the liquid sodium pipe 2 is 300 to 600
Since the leaking sodium of such a device flows into the tank 6 due to the high temperature such as ℃, a rapid gas expansion occurs in the tank, and the pressure in the combustion suppressing tank 6 rises. As a result, leaking sodium cannot pass through the communication pipe 4 into the tank, and further, sodium stored in the tank may flow back through the communication pipe 4, and the upper floor floor liner 3 A large amount of sodium is deposited on the upper side and on the combustion suppressing plate 5, sodium combustion continues on them, and the combustion suppressing effect is significantly reduced. Further, in the worst case, the combustion suppressing tank 6 itself may be damaged.

れたものである。Therefore, in the invention, in the above-described conventional leakage suppression liquid metal storage combustion suppression tank, the expansion gas in the tank generated when the high temperature combustible liquid metal flows in is quickly discharged to suppress the pressure increase in the tank, and It is possible to effectively prevent the phenomenon of blocking the inflow of liquid metal into the tank and the backflow phenomenon of liquid metal to the outside of the tank.
The purpose is to provide an improved combustion suppression tank.

る。<Means for Solving the Problems> In order to achieve the above object, in the present invention, a gas vent for communicating the inside and outside of the tank with a combustion suppression plate at the top of the leakage suppression liquid metal storage combustion suppression tank having the above-described structure. In addition to providing a hole, the gas vent hole is covered with a lid body having a flange portion that covers the outer circumference of the tubular pipe near the opening at one of the upper and lower openings of the tubular pipe with the upper and lower ends open. The gas flow passage is formed by the above.

しまう。<Action> It is easily conceivable that a gas vent hole should be provided in the combustion suppression plate at the top of the tank in order to prevent the pressure in the tank from rising. However, depending on the structure of the gas vent hole, this Since new air flows into the tank through the gas vent hole, the nitrogen extinguishing effect of the liquid metal stored in the tank is reduced.

きる。As in the present invention, if the gas vent passage is formed by the gas flow passage formed by covering the opening having the upper and lower ends with the lid having the flange portion at one opening of the tubular tube with a gap, the gas vent hole is formed in a relatively high temperature tank. Due to the temperature difference between the air and the air at the outlet of the gas vent hole, which has a relatively low temperature, it is possible to prevent natural convection from inflowing the air outside the tank into the tank. It can be discharged from the gas vent hole.

る。FIG. 1 illustrates a state in which a gas vent hole 11 is provided in the combustion suppressing plate 5 at the top of the conventional combustion suppressing tank 6 shown in FIG. 4, and the same members as those in FIG. 4 are the same. The description is omitted by giving reference numbers. FIG. 2 is an enlarged view of the gas vent hole 11 of FIG. 1, and has a lid 14 having an opening on the upper end side of a tubular tube 13 having upper and lower ends open and a flange portion 14a covering the outer circumference of the tubular tube near the opening. It has a structure that covers with a gap. The gas outlet side opening of the gas vent hole 11 faces downward. Even when a rapid gas expansion occurs when the high-temperature liquid metal flows into the tank 6 through the communication pipe 4, the expanded gas is quickly passed through the bent gas flow passage 12 as shown by the arrow. It is discharged to the outside. On the other hand, even when the expanded gas in the tank is not discharged from the gas vent hole 11, the temperature difference between the inside and the outside of the tank prevents the outside air from flowing into the tank due to natural convection.

Can also be attached to the lower end of the communication pipe 4.

口側は上方に向いている。FIG. 3 shows still another embodiment of the gas vent hole, which has a structure in which a lid 24 is covered on the lower end side of the tubular pipe 23, that is, on the opening inside the tank, contrary to the embodiment of FIG. ing. Therefore, the gas flow passage 22 is opposite to that shown in FIG. 2, and the gas outlet side of the gas vent hole 21 faces upward.
ガス抜き孔の開口の大きさは、燃焼抑制板５の面積の約
１％程度の開口率となるようにするのが好ましい。燃焼
抑制槽６が大型になれば、ガス抜き孔も燃焼抑制板の面
積に比例して大きくする必要がある。It is preferable that the size of the opening of the gas vent hole be about 1% of the area of the combustion suppressing plate 5. When the combustion suppressing tank 6 becomes large, the gas vent holes also need to be enlarged in proportion to the area of the combustion suppressing plate.

品がこの開口から槽内に落下する危険がある。そのため
かような上向きの開口は、金網25等を被せることが望ま
しい。Since the gas vent hole 21 as shown in FIG. 3 has the gas outlet side opening facing upward, if the opening diameter is increased, there is a risk that articles may fall into the tank through this opening. Therefore, it is desirable to cover such an upward opening with a metal net 25 or the like.

きる。<Effects of the device> As can be seen from the above, the combustion suppressing tank for storing leaked liquid metal according to the present invention has a gas vent hole formed of a bent gas flow passage in the combustion suppressing plate at the top of the tank. Even if a rapid gas expansion occurs when the metal flows into the tank, the expanded gas can be quickly discharged to the outside of the tank, and the rise in the tank pressure can be prevented. As a result, effectively prevent the phenomenon of blocking the inflow of liquid metal into the tank, the phenomenon of backflow of liquid metal in the tank to the outside of the tank, and the damage to the tank itself, which could occur if there were no vent holes. can do.
