Claims (1)
- 고속 중성자 원자로의 방열판 회로에서 액체 금속 냉각재의 자연 순환을 조직하기 위한 방법으로서,
상기 방열판 회로의 상승 및 하강 구간의 파이프들 및 장비를 예열하고 후속하여 가열된 냉각재로 충전하는 단계, 상기 방열판 회로에서 냉각재 순환을 시작하는 단계, 및 자연 순환 모드로 전환하는 단계를 포함하고,
상기 방열판 회로의 상승 및 하강 구간의 파이프들 및 장비는 이하의 부등식으로부터 선택되는 온도 (T1 및 T2) 까지 각각 전기 가열에 의해 예열되고:
,
여기서,
ρ1(T1) 은 상승 구간에서 파이프들 및 장비의 온도 (T1) 에서의 액체 금속 냉각재의 밀도이고;
ρ2(T2) 은 하강 구간에서 파이프들 및 장비의 온도 (T2) 에서의 액체 금속 냉각재의 밀도이고;
ΔH1 은 상승 구간의 입구와 출구 사이의 높이 차이이고;
ΔH2 은 하강 구간의 입구와 출구 사이의 높이 차이이고;
ΔP 는 회로의 유압 저항이고;
g 는 중력의 가속도이고,
상기 방열판 회로에서 냉각재의 순환은 자연 순환 모드로의 이행과 동시에 시작되어, 상기 방열판 회로의 상승 및 하강 구간에서 각각 액체 금속 냉각재의 밀도 차이 (ρ1(T1) 및 ρ2(T2)) 로 인해 순환 구동 압력을 생성함으로써 원자로가 공칭 작동 파라미터에 도달할 때까지 수행되는 것을 특징으로 하는, 고속 중성자 원자로의 방열판 회로에서 액체 금속 냉각재의 자연 순환을 조직하기 위한 방법.
