Claims (5)
- 피가열유체가 흐르는 연료영역 상부에 구획되어 형성됨과 동시에, 원자로 용기의 측부에 구비된 복수의 출구노즐에 유체 연결소통하는 상부 플리넘에 있어서, 상부 플리넘내의 상부 코아판상의 연료집합체영역보다 외측이면서 코아조의 내벽에 근접하는 위치에서 단척(短尺)의 유동안정부재가 부착되고, 이 단척의 유동안정부재는, 상부 플리넘내에 부착된 때에, 그의 선단이 출구노즐의 내경의 하단보다 낮게 되어 있는 원자로 용기의 노내 구조물.
- 제 1 항에 있어서, 상기 단척의 유동안정부재는 상기 출구노즐의 유출구의 하측에 설치되어 있는 원자로 용기의 노내 구조물.
- 제 2 항에 있어서, 상기 단척의 유동안정부재는 상기 출구노즐의 상기 유출구의 중앙 바로 아래 위치에 설치되어 있는 원자로 용기의 노내 구조물.
- 제 2 항에 있어서, 상기 단척의 유동안정부재는 인접하는 상기 출구노즐 사이에 설치되어 있는 원자로 용기의 노내 구조물.
- 제 3 항 또는 제 4 항에 있어서, 상기 단척의 유동안정부재는 그 상단이 상부 코아판의 상면과 상기 출구노즐의 유출구 하단과의 중간 높이에서 상기 유출구의 상기 하단보다 낮은 높이까지 사이에 위치하는 길이인 원자로 용기의 노내 구조물.
