我国高放废物地下实验室处置工艺现场试验初步探讨

A PRELIMINARY RESEARCH ON ON-SITE TESTS OF DISPOSAL PROCESS IN UNDERGROUND RESEARCH LABORATORY OF HIGH LEVEL RADIOACTIVE WASTE IN CHINA

根据我国地下实验室功能与需求目标,结合我国地下实验室候选场址地质条件、废物源项特征、施工和处置工艺技术水平与设备能力等因素,提出了与处置工艺相关的试验项目。计划开展处置巷道/钻孔开挖试验、处置机具及处置技术试验、全尺度处置库示范试验等现场试验研究,详细阐述了试验的目的、流程、进度和条件等,其将为我国首座地下实验室工程总体建设方案提供重要的输入条件。

Based on the functions and requirements of underground laboratory in China for disposal of HLW（High Level Waste）,the geological and hydrogeological conditions of the site,features of waste source,technic and instrumental issues in construction and disposal process,the investigative content of on-site tests which are related to disposal process have been provided. A series of on-site tests were conducted,including the disposal tunnel or borehole excavation test, the demonstration of disposal machines and disposal techniques, prototype disposal repository and so on. The test purposes,processes,schedules and conditions were stated in detail,which would provide input conditions for construction plan of the first underground research laboratory in china.
