地下废液储存罐放射性淤泥回取方案设计及应用

Design and Application of Radioactive Sludge Cleaning Plan for Underground Wastewater Storage Tank

101堆是我国首个实施退役的重水研究堆,可为我国研究堆退役能力体系的建立和为其他动力堆退役提供技术积累。其中,101堆3个废水罐清理工作是101堆退役期需要解决的重要工作。目前,101堆罐中仍存有少量放射性淤泥有待处理。为了消除废水罐淤泥,开展了101堆废水罐淤泥清理方案设计及实施工作。通过设计淤泥取样和淤泥回收工具,圆满完成了101堆废水罐内的淤泥清理工作,显著降低了罐口放射性水平。

The 101 reactor is the first heavy water research reactor to be decommissioned in China,which can provide strong technical support for the establishment of China’s research reactor decommissioning capacity system and other power reactors decommissioning.Among them,the cleaning of three waste water tanks of 101 reactor is an important work to be solved in the decommissioning period of 101 reactor.At present,there is still a small amount of radioactive sludge in 101 tanks to be disposed of.In order to eliminate the sludge in the waste water tank,this paper carried out the design and implementation of the sludge cleaning scheme for 101 piles of waste water tank.Through the design of sludge sampling and sludge recovery tools,the sludge removal work in the 101 waste water tank was successfully completed,and the radioactive level was significantly reduced.
