中文摘要:

      目的 提出制定我国放射性物质货包运输风险控制目标的初步建议，可为相关风险评价工作提供决策参考。方法 通过借鉴核电厂及非反应堆核设施相关安全目标研究的宝贵经验，对相关阈值划分和风险可接受边界进行讨论，并针对放射性货包运输的特点展开分析，提出以风险矩阵作为其风险目标的表达形式。结果 相关研究认为，对放射性物质货包运输来说，按照严重程度分类，结合其事故发生率，是一种较为合理的表征形式。结论 本文对放射性物质货包运输风险控制目标制定进行了初步的探索。要使得该风险矩阵能与实际运输活动的风险指引相适应，最终起到指导运输风险管理的作用，未来还需要更多研究成果的推动。

英文摘要:

      The work aims to present preliminary suggestions on establishing the risk control goals of radioactive material transportation to provide decision-making reference for relevant risk evaluation. With the experience of safety research work on nuclear power plants and non-reactor nuclear facilities, the work analyzed the characteristics of radioactive material transportation. A risk matrix was proposed to be used as the risk goal for radioactive material transportation by the discussion of the acceptable boundary setting and the risk index values. Based on the research, the risk matrix was considered to be a reasonable presentation form for radioactive material transportation according to its classification of severity in combination with its accident rate. In the work, a preliminary exploration is made on the establishment of risk control goal for packaging and transportation of radioactive materials. Further works need to do before the risk matric is applicable to the actual transportation activities and become the guidance of transport risk management at last.
