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.
