A New Concept to Detect He Leaks on Tore Supra Cryogenic Plant

摘要

One of the main problems encountered in cryogenic helium plants is leaks. The TORE SUPRA cryogenic system is complex and spread over a large area. In order to provide continuous automatic monitoring of the plant, we have developed a new centralized system able to detect and locate leaks in real time. The system essentially ses a mass spectromeeter which continuously analyzes the air helium content. A data storing system provides a mass spectrometer whic continuously analyzes the air helium content. A data storing system provides a posteriori information. This paper presents a comrehensive survery of the equipment developed, along with its performance and sensitivity.
