Abstract:
(EN) Provided are a system and a method for detecting a uranium hexafluoride (UF6) leak. The system for detecting a UF6 leak comprises: a vaporizer (10); a cylinder (11) arranged in the vaporizer (10) and accommodating solid state UF6; a heater (12) provided at the vaporizer (10), and heating the nitrogen gas in the vaporizer (10) so as to heat the cylinder (11); and a detecting sensor (13) arranged on the outside of the vaporizer (10), inducing the nitrogen gas in the vaporizer (10), and having an air supply pump (14), which supplies surrounding air to a special dual nozzle (15) such that the UF6 gas reacts with moisture after the end of the nozzle, thereby sensing the existence of HF gas in real time.
(FR) L'invention concerne un système et un procédé permettant de détecter une fuite d'hexafluorure d'uranium (UF6). Le système de détection d'une fuite d'UF6 comprend : un vaporisateur (10) ; un cylindre (11) disposé dans le vaporisateur (10) et recevant l'UF6 à l'état solide ; un dispositif de chauffage (12) situé au niveau du vaporisateur (10) et chauffant l'azote gazeux dans le vaporisateur (10) de manière à chauffer le cylindre (11) ; et un capteur de détection (13) situé à l'extérieur du vaporisateur (10) et induisant la pénétration de l'azote gazeux dans le vaporisateur (10), et comportant une pompe d'alimentation en air (14) qui achemine l'air environnant vers une buse double spécifique (15) de telle sorte que le gaz UF6 réagisse avec l'humidité au-delà de l'extrémité de la buse, ce qui permet de détecter la présence du gaz HF en temps réel.
(KO) 육플루오르화우라늄(UF6) 누츌 감지 시스템 및 방법이 제공된다. 상기 육플루오르화우라늄(UF6) 누출 감지 시스템은, 기화기(10), 상기 기화기(10) 내부에 배치되고, 고체 상태의 UF6를 수용하는 실린더(11), 상기 기화기(10)에 설치되고, 상기 기화기(10) 내의 질소가스를 가열하여 상기 실린더(11)를 가열하는 히터(12) 및 상기 기화기(10) 외부에 배치되고, 상기 기화기(12) 내의 질소가스를 유도하고 공기공급 펌프(14)는 주변의 공기를 특수 2중 노즐(15)로 공급하여 노즐 끝단 이후에서 UF6 가스와 수분이 반응되도록 하여 HF 가스가 존재하는지 실시간으로 감지하는 감지 센서(13)를 포함한다.
