中文摘要:

      目的 设计一种用于运输工业辐照用特殊形式放射源的运输容器，通过试验验证运输容器的安全性能。方法 根据《放射性物品安全运输规程》和《放射性物质安全运输条例》中B(U)型货包的规定进行设计，设计的运输容器主要包括屏蔽容器、吊篮、防护罩及运输托架4部分组成，并对运输容器进行正常运输工况和运输事故工况下的3次跌落试验。结果 试验对容器外防护罩和保温层造成部分损坏，但防火层完整，不影响包装的密封和屏蔽功能，试验结果表明运输容器满足标准要求。结论 运输容器在正常运输工况和运输事故工况下的跌落测试后，包装的屏蔽和密封仍然有效，即该运输容器在规定的正常运输工况和运输事故工况下能保证放射源的运输安全。

英文摘要:

      The work aims to design a transport containerfor transporting special forms of radioactive sources for industrial irradiation and verify the security of the transport container through experiments. According to the provisions of the B(U) cargo package in the "Regulations for the Safe Transport of Radioactive Materials" and the "Regulations on the Safe Transport of Radioactive Materials", a transport container for transporting special forms of radioactive sources for industrial irradiation was designed, mainly including shielding container, hanging basket, protective cover and transport carrier. The transport container was subject to three drop tests under normal transportation conditions and transport accident conditions. The test caused partial damage to the outer protective cover and insulation layer of the container, but the fire barrier was intact and it did not affect the sealing and shielding functions of the package. The results showed that the transport container met the requirements of the standard. After the drop test of the transport container under normal transport conditions and transport accident conditions, the shielding and sealing functions of the package are still valid. It means that transport containers ensure the safety of the transport of radioactive sources under the specified normal transport conditions and transport accident conditions.
