Claims (4)
- 사용시 안내 딤블내에 위치된 제어봉 단부상에 설치되며 제어봉의 축방향 진동으로 인해 안내 딤블을 타격할 수 있는 단부 플러그를 포함하며, 안내 딤블 내에서 수직 운동을 하는 제어봉을 지지하기 위한 장치를 갖는 원자로용 제어봉에 있어서, 상기 단부 플러그(52)는 단부 플러그와 안내딤블(18)사이에 접촉부를 제공하는 슬리이브(58)를 가지고 있으며, 상기 슬리이브는 안내 딤블과 유사한 물질로 구성되는 것을 특징으로 하는 원자로용 제어봉.
- 제1항에 있어서, 상기 물질은 단부 플러그(52)의 물질과는 상이하며, 상기 슬리이브(58)는 인터록 연결부(78)에 의해 단부 플러그(52)에 부착되는 것을 특징으로 하는 원자로용 제어봉.
- 제2항에 있어서, 인터록 연결부(78)는 단부 플러그(52)의 주변 표면에 형성된 환상홈(84)과, 상기 환상홈(84)에 적재되어 슬리이브(58)의 내측 표면상에 형성된 하나의 주변 벌지(80)로 구성되는 것을 특징으로 하는 원자로용 제어봉.
- 제1항, 2항 또는 3항에 있어서, 안내 딤블은 원자로가 운전중일 때 딤블을 통해 흐르는 냉각재를 가지고 있으며, 슬리이브(58)와 단부 플러그(52)는 액체 냉각제가 그속으로 도입되어 슬리이브와 안내 딤블 사이의 충격을 완화하기에 충분한 방사상 갭을 가지고 있는 것을 특징으로 하는 원자로용 제어봉.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
