Abstract：At present,the nuclear power industry of China is developing rapidly,but the disposal of spent fuel still needs further research.Based on the review of the reprocessing process of spent fuel and the development of spent fuel storage vessels,the characteristics of the chemical composition,solidification process,mechanical properties and heat treatment technology of the ductile iron storage vessels were summarized,and the casting process of the multi-functional ductile iron tank for radioactive materials storage was introduced.Finally,it is pointed out that the spheroidal cast iron tank has a good application prospect in the spent fuel storage container and the medium and low level radioactive waste disposal container.
