Vertical tube of 20-mm inner diameter surrounded by furnaces and insulating sleeves
Gas and wall temperature, pH and pI, aerosol size and composition of the oxide layer and the deposits
Different carrier gas (H2O, H2O/H2, Argon), different tube materials, temperature range 920-1070, different mass flow rate and concentration of FPs
The absorption of simulant fission products compounds onto metal surfaces has been studied in the DEVAP
(CEA/DRN – IPSN) programme
