Description

For the purpose of elucidating the mechanism of the sodium-concrete reaction in a sodium-cooled fast reactors, kinetic study of the sodium (Na)-silica (SiO2) reaction has been carried out by Differential Scanning Calorimetry (DSC) technique. The parameters, including melting point of Na, phase transition temperature of SiO2, and Na-SiO2, reaction temperature have been identified from DSC curves. It was found that reactivity of Na-SiO2 reaction is similar with the reaction between Na and aggregate of practical used concrete. Based on the measured reaction temperature, rate constant of Na-SiO2 reaction was obtained. Thermal analysis results indicated that Na-SiO2 reaction could occur in the timeframe of sodium-concrete reaction. (author)
