Conference Article: Sodium cleaning in Phenix steam generator modules
Gastaldi, O. (Commissariat a l'Energie Atomique (CEA), Saint-Paul-lez-Durance(France)); Grabon, V. (Framatome-ANP, Lyon (France)); Cavagna, C. (CEA-Phenix, Bagnols-sur-Ceze (France))Abstract
The repair of the Phenix steam-generator's modules needed to establish a particular sodium cleaning procedure. The standard Phenix cleaning procedure, using water vapour in presence of nitrogen and carbon dioxide was indeed not suitable, because of bulky sodium residues and specific geometry of modules. A specific procedure, using a gradual water vapour nitrogen process has been developed, qualified and industrially implemented in a very short delay, in order to clean efficiently the steam generators modules, before repair and requalification.
