Description
An automatic liquid nitrogen feeding device has been developed (and used) in the framework of corrosion tests realized with constantly renewed uranium hexafluoride. The issue was to feed liquid nitrogen to a large capacity metallic trap in order to condensate uranium hexafluoride at the exit of the corrosion chambers. After having studied various available devices, a feeding device has been specifically designed to be robust, secure and autonomous, as well as ensuring a high liquid nitrogen flowrate and a highly elevated feeding frequency. The device, made of standard material, has been used during 4000 hours without any problem
Abstract (French)
Un dispositif de remplissage automatique en azote liquide a ete mis au point, realise et utilise. Il permet une grande autonomie, une cadence tres elevee et a ete entierement realise avec du materiel standard. Ce travail a ete rendu necessaire par les caracteristiques des pieges speciaux utilises pour l'hexafluorure d'uranium chaud, dans des ensembles de corrosions de longue duree. La presence dans ces pieges froids de fluides tres corrosifs nous a amenes a prevoir un systeme de securite permettant de proteger l'appareillage en cas d'incident amenant le rechauffage des pieges.
