Description

원자로 용기의 가동중 검사장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 음향 위치결정 장치에 설치된 노즐 스캐너(scanner)를 나타내는, 원자로 용기내 배치되어 도시된 원자로 가동중 검사장치의 일부분의 사시도,
제2도는 제1도에 도시된 본 발명의 노즐스캐너의 사시도.

Claims (1)

  1. 적절한 검사위치에 검사 변환기를 위치결정(positioning)하는 위치결정 아암부(付)검사 변환기를 가지고 있고, 상기 아암이 원자로 용기 중공(中空)내의 공동(空洞)부분내의 미리 정해진 위치에 그 아암을 배치시키기 위한 수단을 가진 원자로 용기 가동중(inservice) 검사장치에 있어서, 상기 배치수단이, 원자로용기 중공의 공동부분의 원주주위에 음향신호를 발생시킴과 동시에 반경방향으로 향하게 하고, 그 중공벽에서 반사되는 신호를 수신하기 위해 위치결정 아암(40)에 부착된 수단(80)과, 시간함수로 상기 수신된 신호를 감시하기 위한 수단과, 원자로용기 중공의 공동부분내의 미리 정해진 위치에, 상기 수신신호들의 수신시간의 감시된 차이에 응하여 상기 아암을 위치 결정하는 수단으로 구성됨을 특징으로 하는 원자로용기의 가동중 검사장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
