核电码头转运乏燃料的辐射防护要求及首次实践

摘要/Abstract

摘要： 基于乏燃料货包特性和核电码头转运乏燃料作业流程,结合国内首艘乏燃料运输专用船参数及辐射防护要求,提出核电码头转运乏燃料的辐射防护要求。在此基础上,从码头临时控制区、专用船货舱区域及码头转运作业人员三个方面开展码头转运乏燃料辐射监测评价,测算单次“公-海”转运6个货包时不同岗位工作人员的个人受照剂量,并与转运过程实测值进行对比分析,结果满足GB 18871对于工作人员的个人剂量限值要求和企业要求,证明核电码头转运乏燃料的辐射防护措施合理有效。

Abstract: Based on the characteristics of spent fuel cargo packages and the operation process of transporting spent fuel at nuclear power plant wharfs, in consideration with the parameters and radiation protection requirements of the first dedicated ship for transporting spent fuel in China, radiation protection requirements for transporting spent fuel at nuclear power plant wharfs are proposed. On this basis, radiation detection and evaluation of spent fuel transportation at the wharf were carried out from three aspects: the radiation operation area of the wharf, the cargo holding area of the dedicated ship, and the personnel involved in the transportation at wharf. The radiation exposure dose of different operation positions during the loading and unloading of six packages in a single transportation was calculated and compared with the measured values during the spent fuel transportation process. The results were far below the radiation limit for professional personnel in GB 18871. Therefore, the radiation protection requirements and measures proposed in this article for the transportation of spent fuel at nuclear power plant wharfs are reasonable and effective.

Key words: nuclear power plants, wharfs, spent fuel, transport packages, radiation protection
