UNDERGROUND BURIAL FACILITY OF RADIOACTIVE WASTE
PROBLEM TO BE SOLVED: To provide an underground burial facility for disposing a low level radioactive waste, using a filling cement composition in which the hardening body is less likely to alter even if it is exposed to an environment including a sulfate or carbonate and the volumetric change is small even if the alteration occurs.SOLUTION: The present invention provides an underground burial facility for a low level radioactive waste in which the water-binding material ratio is 30-70 mass%, and the filling mortar hardening body includes Stratford phosphorus Gaito (2CaO-AlO-SiO-8HO).SELECTED DRAWING: None
【課題】硫酸塩や炭酸塩を含む環境にさらされても、硬化体の変質が少なく、万が一変質しても体積変化の少ない充填セメント組成物を用いた、低レベル放射性廃棄処分用の地中埋設施設を提供する。【解決手段】水結合材比が３０〜７０質量％であり、充填モルタル硬化体中にストラトリンガイト（２ＣａＯ・Ａｌ2Ｏ3・ＳｉＯ2・８Ｈ2Ｏ）を含有する低レベル放射性廃棄物の地中埋設施設。【選択図】なし
