福島第一原子力発電所事故の汚染水処理二次廃棄物等の保管容器の長期健全性評価手法の構築に向けて、高線量の含水廃棄物の崩壊熱による水分蒸発挙動を予測する解析コードの開発を進めている。本報では、セシウム吸着塔を例として、コードの概要と毛管圧力が残水量の挙動に与える影響についての試算例を報告する。

Toward the establishment of a long-term soundness evaluation method of storage vessels, such as zeolite wastes generated by the treatment of radioactive saline water at the Fukushima Daiichi Nuclear Power Station, the analysis code to predict the drying process behavior by the decay heat of the waste. In this paper, as an example the spent zeolite vessel, we report the development status of this code.
