GEOPOLYMER COMPOSITION FOR SOLIDIFYING RADIOACTIVE WASTE
To provide a novel geopolymer composition for solidifying radioactive waste capable of preventing the internal temperature of a solidified body of radioactive material sealed in a container from exceeding 100°C.SOLUTION: A geopolymer composition contains an additive which has a higher thermal conductivity than that of the geopolymer and is dispersed in the geopolymer. The additive may be particulate or fibrous. SiC particles, BN particles, metal fibers, or a combination thereof may be used as the additive. Since the geopolymer composition has a high thermal conductivity, the decay heat of the radioactive waste can be efficiently released to the outside.SELECTED DRAWING: Figure 1
【課題】容器に封入された放射性物質の固化体の内部温度が１００℃を超えることを防止することのできる、新たな放射性廃棄物固化用のジオポリマー組成物を提供する。【解決手段】ジオポリマー中にジオポリマーよりも熱伝導率の高い添加材を分散して含む。添加材は粒子状であっても繊維状であってもよく、ＳｉＣ粒子、ＢＮ粒子、金属繊維、又はこれらの組み合わせを使用することができる。熱伝導率が高いため、放射性廃棄物の崩壊熱を効率良く外に逃がすことができる。【選択図】図１
