Description

해체 원전의 사용후 연료 냉각 설비 전원 공급장치{POWER SUPPLY APPARATUS FOR SPENT FUEL COOLING DEVICE OF DECOMMISION NUCLEAR POWER PLANT}POWER SUPPLY APPARATUS FOR SPENT FUEL COOLING DEVICE OF DECOMMISION NUCLEAR POWER PLANT

본 발명은 비상시 사용후 연료 저장조의 냉각수의 냉각이 가능한 해체 원전의 사용후 연료 냉각 설비 전원 공급장치에 관한 것이다.The present invention relates to a power supply device for a spent fuel cooling facility of a decommissioned nuclear power plant capable of cooling the cooling water of a spent fuel storage tank in an emergency.

일반적으로 원자력 발전용으로 사용된 후의 핵 연료(이하, "사용후 연료"라 칭함)는 특수 설계된 저장 용기에 수납된 상태에서 저장 장소에 보관된다.In general, nuclear fuel after being used for nuclear power generation (hereinafter, referred to as "spent fuel") is stored in a storage place in a state stored in a specially designed storage container.

사용후 연료의 저장 방법은 크게 습식 저장 방법과 건식 저장 방법으로 구분된다. 1980년대 중반까지는 적용 경험이 풍부한 습식 저장 방법이 주로 이용되어 왔으나, 용량 확장과 장기 관리 측면에서 유리한 건식 저장 방법이 채택되었으며, 많은 나라에서 건식 저장 방법을 적용한 건식 저장 시설이 이용되고 있다.A method of storing spent fuel is largely divided into a wet storage method and a dry storage method. Until the mid-1980s, a wet storage method with extensive application experience was mainly used, but a dry storage method advantageous in terms of capacity expansion and long-term management was adopted, and dry storage facilities applying the dry storage method are used in many countries.

한편, 해체가 결정된 원전의 사용후 연료는 사용후 연료 저장조에 이송되어 저장 및 보관된다. On the other hand, the spent fuel of the nuclear power plant that has been decided to be decommissioned is transferred to the spent fuel storage tank and stored and stored.

그러나, 사용후 연료는 해체가 결정된 원자로 건물의 외부에서 사용후 연료의 저장을 위한 연료 저장조를 별도로 설치해야하는 바, 사용후 연료 저장을 위한 추가 공간의 확보가 필요한 문제점이 있다. However, there is a problem in that it is necessary to separately install a fuel storage tank for storage of the spent fuel outside the nuclear reactor building, which has been decommissioned, for the spent fuel, and thus it is necessary to secure an additional space for storing the spent fuel.

또한, 사용후 연료를 저장한 저장조의 내부에 충진된 냉각수의 온도가 비정상적으로 상승되는 경우, 일정 온도 미만으로 냉각하는 것이 필요하지만, 냉각수의 적절한 온도 관리가 불가능하여 냉각수의 원활한 냉각이 이루어지지 않는 문제점이 있다. In addition, when the temperature of the coolant filled in the storage tank storing the spent fuel is abnormally increased, it is necessary to cool it below a certain temperature. There is a problem.

따라서, 냉각수의 온도를 일정온도 미만으로 냉각하고자 냉각 설비를 설치한다. 그러나, 정전 등의 사고로 냉각 설비에 전원이 공급되지 않아 냉각 설비를 구동하지 못하는 경우, 냉각수를 적절한 온도로 냉각하지 못하여 안전사고가 발생될 수 있는 문제점이 있다. Accordingly, a cooling facility is installed in order to cool the temperature of the cooling water below a certain temperature. However, when power is not supplied to the cooling facility due to an accident such as a power outage and the cooling facility cannot be driven, the cooling water cannot be cooled to an appropriate temperature, thereby causing a safety accident.

본 발명의 일 실시예는, 정전 등의 비상시에도 냉각 설비에 원활한 전원 공급이 가능하여 냉각수의 온도를 적절하게 냉각 가능한 해체 원전의 사용후 연료 냉각 설비 전원 공급장치를 제공하고자 한다.An embodiment of the present invention is to provide a power supply device for a fuel cooling facility after use of a decommissioned nuclear power plant capable of properly cooling the temperature of cooling water by smoothly supplying power to the cooling facility even in an emergency such as a power outage.

전원 공급부는, 사용후 연료 저장조의 외부에 설치되어 냉각 설비에 전원을 공급하는 풍력 발전 설비를 포함할 수 있다.The power supply unit may include a wind power generation facility installed outside the spent fuel storage tank to supply power to the cooling facility.

사용후 연료 저장조의 외부에 설치되며, 냉각 설비가 내부에 설치되는 보조 저장조를 더 포함할 수 있다.It is installed outside the spent fuel storage tank, the cooling equipment may further include an auxiliary storage tank installed therein.

풍력 발전 설비와 태양광 발전 설비의 각각에 연결되어 냉각 설비에 공급되는 전원을 저장하는 배터리부재를 더 포함할 수 있다.It may further include a battery member connected to each of the wind power generation facility and the solar power generation facility to store power supplied to the cooling facility.

배터리부재는, 사용후 연료 저장조의 내부에 설치되는 제1 배터리와, 보조 저장조의 내부에 설치되는 제2 배터리를 포함할 수 있다.The battery member may include a first battery installed in the spent fuel storage tank and a second battery installed in the auxiliary storage tank.

본 발명의 일 실시예에 따르면, 외부 전원 공급이 없는 상태에서 태양광 발전 설비와 풍력 발전 설비를 이용하여 냉각 설비에 전원을 공급하여, 외부 전원 공급이 없는 비상시에도 냉각 설비를 안정적으로 구동한 바, 유지 보수 비용의 절감과 냉각수의 온도 상승에 사고 발생을 효과적으로 방지할 수 있다. According to an embodiment of the present invention, power is supplied to the cooling facility by using a solar power generation facility and a wind power generation facility in a state where there is no external power supply, and the cooling facility is stably driven even in an emergency without an external power supply. , it can reduce maintenance costs and effectively prevent accidents caused by the temperature rise of the coolant.
