放射性セシウム(Cs)で汚染された都市ごみの焼却処理では、Csは焼却灰に付着し焼却施設内に留まる。被ばく管理の観点から、Csが付着した焼却灰の焼却施設内の分布情報を得るため、既存焼却炉で燃焼解析を行い焼却灰の挙動を評価している。本報告でこの取り組みを紹介する。

By the thermal disposal of the city garbage polluted with radioactive cesium, Cs adheres to incineration ashes and remains in municipal waste incineration facility. In order to acquire the distribution information in the waste incineration plant of the incineration ashes to which Cs adhered from viewpoints of radiation protection, burning analysis is conducted with the existing incinerator and the action of incineration ashes is evaluated. This approach is introduced by this report.
