Abstract

In this study, various technologies were analyzed to suppress the occurrence of leak due to the difference in heat shrinkage of vacuum container parts. Based on these technologies, a study was conducted on the development of vacuum leakage detection technology for cryogenic containers using helium leak detectors. In addition, a study on vacuum leakage detection using a helium leak detector was conducted to accurately detect the site where a cryogenic container leak occurs. Finally, a vacuum leak detection procedure was established based on the leak detection experiment for the cryogenic container in which the actual leak occurred using a helium leak detector, and it was confirmed that various tests can be conducted depending on the test subject conditions.

본 연구에서는 진공용기 부품의 열수축률 차이로 인한 리크 발생을 억제하기 위한 다양한 기술을 분석하였다. 이러한 기술을 바탕으로 헬륨 누출 감지기를 이용한 극저온 용기의 진공 누출 감지 기술 개발에 관한 연구가 진행되었다. 또한 극저온 용기 누출이 발생하는 부위를 정확하게 검출하기 위해 헬륨 누출 감지기를 이용한 진공 누출 감지에 대한 연구를 진행하였다. 최종적으로 헬륨 누출 감지기를 이용하여 실제 누출이 발생한 극저온 용기에 대한 누출 감지 실험을 바탕으로 진공 누출 감지 절차를 수립하였으며, 실험 조건에 따라 다양한 테스트가 가능함을 확인하였다.
