The present invention relates to an apparatus for sucking auxiliary supply water in a nuclear power plant, and more particularly, to a sucking apparatus for a driven auxiliary water supply system in a nuclear power plant capable of supplying cooling water through various sucking sources to a driven condensing tank.

원자력발전소는 연료의 핵분열에 의해 생성된 열에너지를 이용하여 증기발생기를 통과하는 물에 열을 전달하여 증기를 발생시키고, 발생된 증기에 의해 터빈과 발전기를 가동시켜 전기에너지를 얻는 설비이다. Nuclear power plants use heat energy generated by fission of fuel to transfer heat to water passing through the steam generator to generate steam, and to generate electric energy by operating the turbine and generator by the generated steam.

원자력발전소는 핵연료를 보유하고 있는 원자로 노심과, 원자로에서 발생한 열에너지를 이차측으로 전달하는 원자로 냉각재 계통을 설계기준 범위 내에서 안전하게 운전되도록 함으로써 원자력발전소의 안전상태를 유지하고, 방사능 물질의 확산을 방지하기 위한 설비가 구비되어야 한다.Nuclear power plants maintain the safety status of nuclear power plants and prevent the spread of radioactive materials by ensuring that nuclear reactor core with nuclear fuel and reactor coolant system that transfers heat energy generated from nuclear reactor to secondary side are operated safely within the design standard range. .

이를 달성하기 위하여 원자력발전소는 사고 발생시 발전소를 안전하게 정지시킬 수 있도록 공학적 안전설비 계통을 갖추고 있다. 공학적 안전설비 계통은 격납용기계통(Containment System), 비상노심냉각계통(Emergency Core Cooling System), 피동보조급수계통(Passive Auxiliary Feedwater System)을 포함한다.To achieve this, the nuclear power plant has an engineering safety system to safely shut down the power plant in the event of an accident. Engineering safety systems include Containment System, Emergency Core Cooling System, and Passive Auxiliary Feedwater System.

상기 피동보조급수계통의 일례로, 도 1은 대한민국 등록특허 제10-1022164호에 개시된 경수로의 피동 이차측 응축계통을 나타낸 것이다. 도 1을 참조하면, 종래 경수로의 피동 이차측 응축계통은, 원자로의 열에 의해 증기를 발생시키는 증기발생기(10), 상기 증기발생기(10)의 열을 터빈 측으로 공급하는 주증기관(11), 터빈을 거친 증기가 냉각수와의 열교환에 의해 응축된 물이 증기발생기(10)로 회수되는 주급수관(12), 원자로 운전 중단시 터빈 측으로의 증기 공급을 차단하고 주증기관(11)으로부터 분기되는 증기공급관(13)을 통하여 유입되는 증기를 피동응축탱크(30) 내부에 담긴 응축기(20)에서의 열교환에 의해 물로 응축시킨 후, 응축기(20)의 출구에 연결된 응축수회수관(14)을 통해 응축된 물을 주급수관(12)으로 합류시키도록 구성되어 있고, 응축수회수관(14)에는 응축된 물의 역류방지를 위한 역류방지부(40)가 설치된 구성이 개시되어 있다.FIG. 1 shows a secondary side condensation system of a light-water reactor disclosed in Korean Patent No. 10-1022164. 1, a driven secondary side condensing system of a light-water reactor includes a steam generator 10 for generating steam by the heat of a reactor, a main engine 11 for supplying heat of the steam generator 10 to the turbine side, A main water supply pipe 12 through which steam condensed by heat exchange with the cooling water is recovered to the steam generator 10, a steam supply pipe 12 which interrupts the steam supply to the turbine side when the reactor operation is interrupted, The condensed water is condensed through the condensate return pipe 14 connected to the outlet of the condenser 20 after the steam flowing through the condenser 20 is condensed into water by heat exchange in the condenser 20 contained in the passive condensation tank 30, And the water is joined to the main water supply pipe 12, and the backflow preventing portion 40 for preventing backflow of condensed water is provided in the condensate return pipe 14. [

이와 같은 피동 이차측 응축계통에 의하면, 펌프와 같은 별도의 능동수단을 구비하지 않고 자연 대류방식에 의해 증기발생기(10)에서 발생된 증기를 응축기(20)에서 응축시킨 후 증기발생기(10)로 환수시켜 원자로를 냉각시킴으로써 원자력발전소의 사고시에 원자로의 과열을 방지할 수 있는 장점이 있다.
According to such a driven secondary side condensation system, the steam generated in the steam generator 10 is condensed in the condenser 20 by the natural convection system without any separate active means such as a pump, By cooling the reactor, it is possible to prevent overheating of the reactor at the time of the accident of the nuclear power plant.

상기 피동응축탱크(30)에 충수된 냉각수 50만 갤런이며, 최소 8시간의 냉각기능을 확보하고 있다. 이러한 냉각 가능 시간의 한정은 피동응축탱크(30) 내의 냉각수가 응축기(20)와 열교환 되어 점차 그 온도가 상승하게 되어, 결국 응축기(20)를 통해 응축을 시킬 수 없는 상황까지 발생하게 되기 때문에 발생한다.
The cooling water introduced into the passive condensation tank 30 is 500,000 gallons, and a cooling function of at least 8 hours is ensured. This limitation of the cooling time is caused by the fact that the cooling water in the passive condensation tank 30 is heat-exchanged with the condenser 20 so that the temperature thereof gradually rises and consequently the condensate can not be condensed through the condenser 20 do.

따라서 피동응축탱크(30)에 의해 8시간 정도의 사고에 대해서는 피동보조급수계통이 원활하게 작동하여 냉각을 수행하게 되나, 최근 일본 후쿠시마 원전사고와 같이 사고가 장기간 지속되는 경우에는 피동보조급수계통이 작용하지 못하게 되는 문제점이 있었다.

또한 상기 제1 및 제2피동응축탱크(110,120)에 직결되는 제1 및 제2공급관(510,520)을 두어 외부에서 소방펌프차(500)에서 냉각수를 제1 및 제2피동응축탱크(110,120)에 직접 공급하는 것이 가능하도록 구성된다.
The first and second supply pipes 510 and 520 are connected to the first and second passive condensation tanks 110 and 120 so that the cooling water is directly discharged from the fire pump car 500 to the first and second driven condensation tanks 110 and 120 And the like.

이하, 상기와 같이 구성되는 본 발명의 바람직한 실시예에 따른 원자력발전소 피동보조급수계통의 충수 장치의 구성과 작용을 보다 상세히 설명한다.
Hereinafter, the construction and operation of the sucking device of the driven auxiliary water supply system of the nuclear power plant according to the preferred embodiment of the present invention will be described in detail.

먼저, 제1 및 제2복수기 탱크(310,320)는 터빈의 구동에 사용된 증기를 응축시켜 재사용 가능하도록 하는 복수기에 마련된 것으로 통상 각각의 용량이 23만 갤런 정도이다.
First, the first and second condenser tanks 310 and 320 are provided in a condenser for condensing the steam used for driving the turbine so as to be reusable, and usually have a capacity of about 230,000 gallons.

그리고 제1 및 제2탈기기 탱크(210,220)는 발전소 플랜트 설비에 공급되는 급수중 용해되어 있는 용존산소 및 이산화탄소를 탈기하여, 플랜트의 부식 방지 역할을 하는 탈기기에 마련되어 있는 것으로, 항상 탈기를 위한 급수가 저장되어 있다.The first and second deaerator tanks 210 and 220 are provided in the deaerator for degassing the dissolved oxygen and carbon dioxide dissolved in the feed water supplied to the power plant plant facility to prevent corrosion of the plant. The water supply is stored.

상기 제1 및 제2탈기기 탱크(210,220)의 용량은 약 27만 갤런이다.
The capacity of the first and second deaerator tanks 210 and 220 is about 270,000 gallons.

사고의 발생시 상기 제1 및 제2피동응축탱크(110,120)에 충수된 냉각수에 의하여 증기발생기의 증기를 응축하여, 이를 원자로로 재공급하여 실질적으로 원자로를 냉각시키는 피동보조급수계통이 작동하게 된다.A driven auxiliary water supply system for condensing the steam of the steam generator by the cooling water introduced into the first and second driven and condensed tanks 110 and 120 and re-supplying the steam to the reactor to cool the reactor substantially operates when an accident occurs.

앞서 설명한 바와 같이 상기 제1 및 제2피동응축탱크(110,120)의 냉각수로는 피동보조급수계통의 냉각 동작을 8시간 정도 유지할 수 있으나, 이 시간이 경과하면 제1 및 제2충수펌프(410,420)에 의해 상기 제1 및 제2탈기기 탱크(210,220)에 저장된 물이 제1 및 제2피동응축탱크(110,120) 각각에 공급된다.
As described above, the cooling operation of the driven auxiliary water supply system can be maintained for about 8 hours with the cooling water of the first and second driven condensation tanks 110 and 120. However, when the time passes, the first and second auxiliary pumps 410 and 420, Water stored in the first and second deaerator tanks 210 and 220 is supplied to the first and second driven condensation tanks 110 and 120, respectively.

이때 제1 및 제2피동응축탱크(110,120)에서 열교환에 의해 온도가 상승한 냉각수는 오버플로우 되도록 할 수 있으며, 상기 제1 및 제2탈기기 탱크(210,220)의 물이 제1 및 제2피동응축탱크(110,120)로 공급됨에 따라 제1 및 제2피동응축탱크(110,120) 내의 냉각수 온도는 낮아지게 되며, 그 내부의 응축기를 통해 스팀발생기의 스팀을 응축하여 원자로로 공급하는 동작을 유지할 수 있게 된다.
At this time, the cooling water whose temperature has risen due to the heat exchange in the first and second passive condensation tanks 110 and 120 can overflow, and the water of the first and second deaerator tanks 210 and 220 can flow through the first and second driven condensing As the cooling water is supplied to the tanks 110 and 120, the temperature of the cooling water in the first and second driven and condensed tanks 110 and 120 is lowered and the operation of supplying the steam generated by the steam generator through the condenser is condensed and maintained in the reactor .

또한 상기 제1 및 제2복수기 탱크(310,320)의 물은 복수펌프(400)를 통해 상기 제1 및 제2탈기기 탱크(210,220)로 공급되어, 지속적으로 제1 및 제2피동응축탱크(110,120)에 냉각수를 충수 할 수 있게 된다.
The water in the first and second condenser tanks 310 and 320 is supplied to the first and second deaerator tanks 210 and 220 through the plurality of pumps 400 and continuously supplied to the first and second driven condensation tanks 110 and 120 The cooling water can be sucked in.

이와 같은 동작에 의하여, 피동보조급수계통의 동작 시간을 연장할 수 있으며, 사고가 장기간 이어지는 경우에도 피동보조급수계통의 작동을 보장할 수 있게 된다.
By this operation, the operation time of the driven auxiliary water supply system can be extended, and the operation of the driven auxiliary water supply system can be ensured even if the accident continues for a long period of time.

상기 제1 및 제2탈기기 탱크(210,220)와 제1 및 제2복수기 탱크(310,320)의 물을 모두 소진한 경우, 상기 제1 및 제2피동응축탱크(110,120) 각각으로부터 원자로건물의 외부까지 연장된 제1 및 제2공급관(510,520)을 통해 소방펌프차(500)의 물을 제1 및 제2복수기 탱크(310,320)에 직접 충수 한다.
When the water in the first and second deaerator tanks 210 and 220 and the first and second condenser tanks 310 and 320 are exhausted from the first and second driven condensation tanks 110 and 120 to the outside of the reactor building The water of the fire pump car 500 is directly supplied to the first and second condenser tanks 310 and 320 through the extended first and second supply pipes 510 and 520.

도 3은 본 발명의 다른 실시예에 따른 원자력발전소 피동보조급수계통의 충수 장치의 구성도이다.3 is a block diagram of an impounding device for a driven auxiliary water supply system of a nuclear power plant according to another embodiment of the present invention.

도 3을 참조하면 본 발명의 다른 실시예에 따른 원자력발전소 피동보조급수계통의 충수장치는, 상기 도 2의 구성에서 제1 및 제2충수펌프(410,420)을 사용하지 않고, 제1 및 제2탈기기 탱크(210,220)의 물을 제1 및 제2피동응축탱크(110,120)에 공급하는 가동급수펌프(430)를 사용한다.Referring to FIG. 3, according to another embodiment of the present invention, the first and second sucking pumps 410 and 420 are not used in the configuration of FIG. 2, A movable water feed pump 430 for supplying water from the deaerator tanks 210 and 220 to the first and second driven condensation tanks 110 and 120 is used.

상기 제1 및 제2충수펌프(410,420)는 기존 발전소 설비에는 마련되어 있지 않은 것이며, 가동급수펌프(430)는 기존 발전소 설비에 포함된 것을 그대로 사용한다는 점에서 차이가 있다.The first and second impregnation pumps 410 and 420 are not provided in the existing power plant equipment, and the movable feed water pump 430 is different from the existing ones in that the existing power plant equipment is used as it is.

즉 가동급수펌프(430)를 사용하는 경우 새로운 설비를 추가하지 않고, 기존 원자력발전소 설비를 그대로 사용하는 것이 가능하게 된다.
That is, when the movable feedwater pump 430 is used, it is possible to use existing nuclear power plant facilities without adding new facilities.

다른 구성과 작용은 앞선 실시예와 동일한 것이며, 이에 대한 상세한 설명은 앞선 실시예에서 충분히 설명되었기 때문에 생략한다.
Other configurations and operations are the same as those in the previous embodiment, and a detailed description thereof is omitted because it has been fully described in the preceding embodiments.

이처럼 본 발명은 다양한 충수원을 사용하여 피동응축탱크에 냉각수를 공급할 수 있게 되어, 피동보조급수계통의 원활한 작동 시간을 연장할 수 있게 된다.
As described above, according to the present invention, it is possible to supply cooling water to the passive condensation tank by using various types of appurtenant, so that the smooth operation time of the driven auxiliary water supply system can be extended.

본 발명은 상기 실시예에 한정되지 않고 본 발명의 기술적 요지를 벗어나지 아니하는 범위 내에서 다양하게 수정, 변형되어 실시될 수 있음은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 있어서 자명한 것이다.
