[2M14] Investigation of in-reactor cesium chemical behavior in TEPCO’s Fukushima Daiichi Nuclear Power Station accident
(4)Quantum modelling of Cs substances in the case of LWR severe accident
Keywords:Cesium , silicates, DFT, Thermodynamic
Theoretical calculations were conducted in order to provide the unknown thermochemical properties of Cs-Si-Fe-O systems for the establishment of Cs chemisorption model based on the mass transfer theory. The computational methodology was validated by calculating the thermal properties of Cs2Si4O9 revealing a good agreement with the literature data.
