一种低中水平放射性废物岩洞处置的方法及结构
摘要：
本发明公开一种用于低中水平放射性废物岩洞处置的方法，包括以下步骤：S1，在地下的岩洞内设置处置巷道，在处置巷道的下部设置单元格；S2，将放射性废物按照放射性活度的高低划分为三个等级，分别为中水平放射性废物、低水平放射性废物、极低水平放射性废物，并将中水平放射性废物、低水平放射性废物按自下而上的顺序依次码放在处置巷道下部的单元格内，再将极低水平放射性废物码放在处置巷道的单元格的顶部，直至填满处置巷道；S3，对处置巷道进行回填、密封。本发明还公开了一种用于低中水平放射性废物岩洞处置的结构。本发明可以有效提高岩洞处置的空间利用率。
摘要（英）：

The invention discloses a method for disposing low-medium-level radioactive waste caves. The method comprises the following steps: step 1, arranging a disposal roadway in an underground cave, and arranging cells at the lower part of the disposal roadway; step 2, dividing radioactive waste into three levels including medium-level radioactive waste, low-level radioactive waste and extremely-low-level radioactive waste according to radioactive activity, stacking the medium-level radioactive waste and the low-level radioactive waste in the cells located at the lower part of the disposal roadway insequence from the bottom to the top, and stacking the extremely-low-level radioactive waste at the tops of the cells of the disposal roadway until the disposal roadway is filled; and step 3, carryingout backfilling on the disposal roadway and carrying out sealing. The invention further discloses a structure for disposing the low-medium-level radioactive waste. The method provided by the invention can effectively improve the space utilization rate of cave disposal.
