Description

The municipal solid waste incineration ash from the Fukushima Prefecture includes radioactive Cs. There is a need to grasp the basic physical properties of this ash, determine the leaching properties of radioactive Cs, and examine leaching suppression methods in order to continue to advance appropriate disposal techniques. For this purpose, we carried out material sampling from a municipal solid waste incineration plants in the Fukushima Prefecture in summer and winter. We then conducted tests on the samples. Results showed that the radioactive Cs leaching suppression method for mixing clay minerals at weight ratio of 5 to 20% can become an effective safety measure. (author)

Abstract (Japanese)

福島県内より生じる一般廃棄物焼却灰には放射性Cs を含むものがあり,適性処分を進めていくには,その基礎的な物性や放射性Cs 溶出性の把握,溶出抑制方法の検討が必要である.そのため,県内にある一般廃棄物焼却施設より,夏季と冬季にそれぞれ試料採取を行い,それらに関する試験を実施.その結果,放射性Cs 溶出抑制方法として,重量比5%から20%の粘土鉱物の混練が有効な安全対策の1つとなりえることも明らかとした.(著者)
