The interaction between Cs2MoO4 and concrete within the temperature range of 600 – 150°C in Ar gas is studied. The reaction products included cesium silicate compounds will be analyzed by XRD, EPMA, and micro-Raman. The obtained result will be contributed for the fundamental understanding on the chemical behavior of Cs2MoO4 in BWR severe accidents.
