摘要
本文探讨我国高放废物地质处置的战略规划 ,提出我国高放废物处置库的开发可参考采用“三步曲”式的技术路线 ,即处置库选址和场址评价 特定场址地下实验室研究 处置库建设。处置库的选址和场址评价工作可与地下实验室研究的相关工作结合。以 2 0 40年前后建成处置库为目标 ,把工作划分为 4个阶段 ,即选址和场址评价阶段、场址确认和地下实验室建设阶段、现场实验和示范处置阶段及处置库建设阶段 ,规划出各阶段的工作目标和工作内容。论证各项工作内容之间的逻辑关系 ,指出选址和场址评价是基础、基础研究和地下实验室研究是支撑、性能评价是“指挥棒”、设计并建造出符合标准的处置库是目标。将选址工作划分为预选地段对比、预选场址对比和场址确认 3个阶段。按此规划设想 ,我国将在 2 0 1 5年以前确定处置库和地下实验室的场址 ,并开始建造地下实验室。 2 0 2 5年左右建成地下实验室 ,2 0
A strategic program for deep geological disposal of high level radioactive waste in China is proposed in this paper.A“3-step technical strategy”:site selection & site characterization—site specific underground research laboratory—final repository,is proposed for the development of China's high level radioactive waste repository.The activities related with site selection and site characterization for the repository can be combined with those for the underground research laboratory.The goal of the strategy is to build China's repository around 2040,while the activities can be diveded into 4 phases:1)site selection & site characterization;2)site confirmation & construcation of underground research laboratory,3)in-situ experiment and disposal demonstration,and 4)construction of repository.The targets and tasks for each phase are proposed.The logistic relationship among the activities is discussed.It is pointed out that the site selection and site characterization provide the basis for the program,the fundamental study and underground research laboratory study are the key support,the performance assessment plays a guiding role,while the construction of a qualified repository is the final goal.The site selection can be divided into 3 stages:comparison among pre-selected areas,comparison among pre-selected sites and confirmation of the final site.According to this strategy,the final site for China's underground research laboratory and repository will be confirmed in 2015,where the construction of an undeground laboratory will be started.In 2025 the underground laboratory will have been constructed,while in around 2040,the construction of a final repository is to be completed.
