摘要
“十三五”期间我国核电站所需外运乏燃料约为“十二五”期间的五倍多,运输量急剧增加。从长远看,我国目前的乏燃料公路运输模式不可持续,急需开展适合大批量长距离的铁路运输模式。本文在研究我国乏燃料铁路运输法规要求的基础上,结合事故情景和运输线路影响因素分析,开展了乏燃料铁路运输路线选择模型的研究。建立了乏燃料铁路运输路线选择评价指标体系,并通过耦合层次分析法和最近邻法,根据重要性对各指标赋予不同权重,根据加权距离选择较优线路,使得评价结果更加合理。利用该模型对某核电站乏燃料铁路运输拟选择的两条线路进行评价,评价结果与相关专家研究结果一致,表明本文建立的模型为我国乏燃料铁路运输路线选择提供了一种可行的评价手段。
During the"13th Five-Year Plan"period,the total amount of spent fuel required for nuclear power plants will exceed 3,000 groups,about five times that of the"12 th Five-Year Plan",and the demand for transportation will increase sharply.In the long run,China’s current mode of spent fuel transportation is not sustainable,and it is urgent to develop a railway transportation mode suitable for large-scale long-distance transportation.On the basis of studying the requirements of China’s spent fuel railway transportation regulations,combined with the accident scenario analysis and transportation route influencing factors analysis.The research on the selection model of spent fuel railway transportation line was carried out.An evaluation index system for the selection of spent fuel railway transportation routes was established.Coupling analytic hierarchy process and nearest neighbor method,different weights are assigned to each indicator according to the importance,and the optimal route is selected according to the weighted distance,which makes the evaluation results are more reasonable.This model is used to evaluate two routes to be selected for an nuclear power plant railway transportation.The evaluation results are consistent with the relevant experts’research results,indicating that the model established in the paper provides a feasible evaluation method for the selection of spent fuel railway transportation routes in China.
