Comparative kinetic study for the thermal decomposition of structural concretes used in the sodium-cooled fast reactor

Koga, Nobuyoshi*; Kikuchi, Shin  

Detailed understanding of the thermal decomposition of the structural concretes used in the sodium-cooled fast reactor is essentially important to simulate the possible phenomena that occurs under postulated severe accident of the nuclear power plant. In this study, thermal decomposition behaviors of siliceous and perlite concretes used in the nuclear power plant were comparatively investigated using thermoanalytical techniques.
