中文摘要:
      目的 介绍我国放射性物品运输容器定期安全性能评价的相关标准和要求,并着重介绍我国现有3种不同型号的压水堆新燃料组件运输容器定期安全评价工作。方法 根据GB 11806等标准规范的要求,检查容器的使用维护历史,通过一系列的现场实验和数据分析,对容器结构、包容、传热、屏蔽和防止临界等5个方面的安全性能进行系统评价。结果 通过对245台不同型号的PWR燃料组件运输容器的现场检查结果分析,容器主要存在防腐层损伤、吊耳焊缝裂纹、密封垫开裂老化等安全隐患。结论 该项工作全面系统地总结了我国压水堆新燃料组件运输容器的安全现状,特别是验证了我国使用了20余年的新燃料组件运输容器的安全性能,具有重要的现实意义。同时,对今后放射性物品运输容器的设计、使用、维护等方面进行了经验总结和反馈。
英文摘要:
      The work aims to introduce the relevant standards and requirements for regular safety performance evaluation of radioactive materials transport containers in China, and emphatically introduce the regular safety evaluation of the existing three different types of PWR fuel assembly transport containers in China. According to the requirements of GB 11806 and other standard specifications, the history of the use and maintenance of containers was inspected. Through a series of on-site experiments and data analyses, the safety performances of the container were evaluated, including structure, containment, heat transfer, shielding and criticality prevention. Through the analysis of the on-site inspection results of 245 different types of PWR fuel assembly transport containers, there were major safety hazards of the container, such as anticorrosive coating damage, lug weld cracks, and sealing gasket cracking and aging. The above-mentioned work summarizes the current safety status of China's PWR fuel assembly transport containers, and in particular verifies the safety performance of the new fuel assembly transport container used in China for more than 20 years, which has important practical significance. At the same time, experience summary and feedback on the design, use, maintenance and other aspects of transport containers for radioactive materials in the future have been made.
