- 수소가 격실 또는 격납건물 내로 방출되는 사고 시에 발생되는 수소를 수소혼합 유도 노즐장치의 노즐부를 통하여 격실 또는 격납건물 내로 방출시키는 단계를 포함하는 수소혼합 유도방법에 있어서,
상기 수소혼합 유도 노즐장치는
원자로 냉각재계통에서 발생하는 수소가 모이는 원자로 냉각재계통 가압기;
상기 가압기와 연결되어 상기 모인 수소가 이동하는 배관부;
상기 배관부에 배치된 안전감압밸브;
상기 배관부의 타단에 연결되고, 원자로의 격납건물 또는 격실 내에 위치하여, 수소를 격납건물 또는 격실로 방출하는 노즐부를 포함하고,
상기 노즐부는 상기 가압기로부터 격납건물 또는 격실 내로 수소를 방출하는 방출구 및 상기 방출구의 중앙에 배치된 확산부를 포함하여, 상기 방출된 수소가 동심 제트를 형성하며 격납건물 또는 격실 내 대기와 혼합되도록 하는 피동형 수소혼합 유도 노즐장치이고,
상기 확산부의 단면적은 상기 방출구의 내부에서 외부로 갈수록 증가하고,
상기 방출구는 상기 배관부로부터 멀어질수록 외경이 증가하고,
상기 확산부의 외부면은 상기 방출구의 외경을 따라 배치되고,
상기 노즐부를 통해 방출된 수소는 동심 제트를 형성하여 상기 노즐부에서 멀어질수록 전단면적이 증가함으로써 방출되는 소수의 농도가 낮아지는 피동형 수소혼합 유도방법.
