[1G02] Thermodynamic stability of volatile radionuclides in cladding failure accident of sodium–cooled fast reactor

*Ikuo Yamamoto1, Munemichi Kawaguchi1, Shinya Miyahara1, Masayoshi Uno1 (1. University of Fukui)

Keywords:Sodium cooled fast reactor, Source term, Volatile radionuclide, Thermodynamic calculation

Thermodynamic calculation on volatile radionuclides such as Cs, I and Te in cladding failure accident of a sodium-cooled fast reactor has been conducted to investigate the chemical form and chemical reaction required for evaluation of an in-vessel source term.
