Application of Dry Storage Technology for Spent Fuel and Key Points of Aging Management
The work aims to summarize the technical characteristics and application of different spent fuel storage methods and explore the key points of dry storage technology to carry out aging management.The technical characteristics of important structural components and the implementation methods of safety functions were analyzed based on the application examples of dry storage technology and the aging mechanism of important safety components and materials was summarized.Dry storage was a mature technology for intermediate storage of spent fuel.For engineering,a specialized Aging Management Plan(AMP)should be developed to mitigate the effects of aging through measures such as aging prevention,aging mitigation,aging impact testing,and safety performance monitoring.It is recommended to increase the innovation of dry storage technology products for spent fuel,develop suitable storage facilities or containers for the development needs of nuclear power in China and conduct research on aging mechanisms and accumulating data,to provide technical support for aging management work in China.
