軽水炉シビアアクシデント時に起こる原子炉構造材へのセシウム(Cs)化学吸着で生成する可能性があるCsFeSiO$$_{4}$$について、再蒸発挙動評価に資するため、高温での蒸発挙動の雰囲気依存性をTG-DTA実験により評価した。その結果、空気及びAr(不活性)雰囲気下と比べて、水素を含む雰囲気下でCsFeSiO$$_{4}$$の蒸発が促進されることが分かった。

In severe accident condition, CsFeSiO$$_{4}$$ could be formed by Cesium(Cs) chemisorption onto reactor structural materials. For evaluation of re-vaporization behavior, effect of atmosphere on the vaporization behavior of CsFeSiO$$_{4}$$ at high temperature was investigated by TG-DTA experiments. As a result, it was found that vaporization of CsFeSiO$$_{4}$$ in atmosphere containing H$$_{2}$$ was promoted more than those in air and in Ar(inert) atmosphere.
