Description

원전 주제어실의 냉각을 위한 피동형 냉각장치{Passive cooling device for cooling main control room of nuclear power plant}Passive cooling device for cooling main control room of nuclear power plant}

본 발명은 원전 주제어실의 냉각을 위한 피동형 냉각장치에 관한 것이다. The present invention relates to a passive cooling device for cooling the main control room of a nuclear power plant.

종래 원전 설계에서 전원이 모두 상실되었을 경우에 원전 가동을 제어하는 주제어실의 공기조화 계통(Heating, Ventilation & Air Conditioning, HVAC)도 정지하게 된다. In a conventional nuclear power plant design, when all power is lost, the air conditioning system (Heating, Ventilation & Air Conditioning, HVAC) of the main control room that controls the operation of the nuclear power plant is also stopped.

원전 주제어실의 공기조화 계통이 정지 할 경우 주제어실의 온도는 장비, 조명, 운전원 등에 의해 서서히 상승하게 된다. When the air conditioning system in the main control room of a nuclear power plant is stopped, the temperature in the main control room gradually rises due to equipment, lighting, and operators.

발전소 내 주제어실의 급격한 온도 상승은 안정성을 떨어트리며, 안정적인 발전소의 운영에도 심각한 문제를 일으키게 된다.A sudden temperature increase in the main control room in a power plant reduces stability and causes serious problems in the stable operation of a power plant.

따라서 발전소 내 전원상실(AC전원)에 따른 주제어실의 공기조화계통이 정지하더라도 주제어실 내 온도 상승을 방지하여 안정성을 높일 수 있는 피동형 냉각장치와 같은 구성이 필요하다. Therefore, even if the air conditioning system of the main control room is stopped due to power loss (AC power) in the power plant, a configuration such as a passive cooling device that can increase stability by preventing a temperature rise in the main control room is required.

냉각수 탱크(200)로부터 냉각수가 냉각판(300)을 통해 냉각 파이프(P)로 공급되고, 공급된 냉각수가 냉각 파이프(P)를 따라 순환하게 된다. Cooling water from the cooling water tank 200 is supplied to the cooling pipe P through the cooling plate 300, and the supplied cooling water circulates along the cooling pipe P.

도 2를 참조하면 설치되는 냉각 파이프(P)의 형태 및 길이는 벽체(T)의 길이 및 주제어실 내부공간(S)의 크기에 따라 다양하게 변경 가능하며, 본 발명의 일실시예에서는 설치되는 냉각 파이프(P)의 형태가 뒤집어진 ‘U’자 형으로 도시되어 있으나, 이에 한정되지 않는다.Referring to FIG. 2, the shape and length of the cooling pipe (P) to be installed can be variously changed according to the length of the wall (T) and the size of the internal space (S) of the main control room, and in one embodiment of the present invention, The shape of the cooling pipe (P) is shown as an inverted 'U' shape, but is not limited thereto.

냉각핀(400)은 냉각판(300)과 접촉하며 벽체(T)에서 내부공간(S)을 향해 돌출되어 있다. 다른 실시예에서 냉각핀(400)은 내부 열전달체(100)와 일부가 접촉되어 있는 형태로 마련될 수 있다.The cooling fins 400 contact the cooling plate 300 and protrude from the wall T toward the inner space S. In another embodiment, the cooling fin 400 may be provided in a form in which a portion of the cooling fin 400 is in contact with the internal heat carrier 100 .

본 발명의 일실시예에서 냉각핀(400)은 격자형으로 이루어져 있으나 이에 한정되지 않으며, 다른 실시예에서는 안테나형과 같이 다양한 형태로 구성될 수 있다. In one embodiment of the present invention, the cooling fin 400 is formed in a lattice shape, but is not limited thereto, and in another embodiment, it may be configured in various forms such as an antenna type.

냉각핀(400)은 주제어실 내부공간(S)의 공기와 직접적으로 접촉함으로써 온도가 상승한 주제어실 내부공간(S)과 열을 떨어트릴 수 있다. The cooling fins 400 may separate heat from the internal space S of the main control room, where the temperature has risen, by directly contacting air in the internal space S of the main control room.

도 1에 도시되어 있듯이, 내부 열전달체(100)의 적어도 일부는 냉각판(300)의 두께 내에 위치하게 된다. As shown in FIG. 1 , at least a portion of the internal heat carrier 100 is positioned within the thickness of the cooling plate 300 .

As the cooling water circulates in the cooling pipe (P), the heat absorbed in the internal space (S) of the main control room is cooled through the internal heat carrier (100), and through this, the temperature in the internal space (S) of the main control room is lowered.

이후 내부 열전달체(100)를 통해 주제어실 내부공간(S) 내 발생되는 열을 벽체(T)의 두께 방향을 따라 주 제어실 외부로 전달(열교환)함으로써 주제어실 내 온도 상승을 방지하며 이를 통해 주제어실의 안정적인 운영이 가능하게 된다.Thereafter, the heat generated in the internal space (S) of the main control room is transferred (heat exchange) to the outside of the main control room along the thickness direction of the wall (T) through the internal heat transfer body (100) to prevent an increase in temperature in the main control room, and through this, the main control room Stable operation of the room is possible.

전술한 실시예들은 본 발명을 설명하기 위한 예시로서, 본 발명이 이에 한정되는 것은 아니다. 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이로부터 다양하게 변형하여 본 발명을 실시하는 것이 가능할 것이므로, 본 발명의 기술적 보호범위는 첨부된 특허청구범위에 의해 정해져야 할 것이다. The above-described embodiments are examples for explaining the present invention, but the present invention is not limited thereto.
