| Popis: | A large amount of radioactive waste liquid is generated in the spent fuel reprocessing process, and high-level waste is stored in a high-level waste tank. During storage, a hydrogen explosion accident may occur, resulting in the leakage of radioactive materials. This article reviewed the basic situation of high-level waste liquid and high-level waste storage system. The safety analysis of the hydrogen explosion accident was conducted, from the source and generation mechanism of hydrogen, the accumulation process of hydrogen in the tank, the possible ignition source and the possibility of explosion in the tank, the pressure generated by the hydrogen explosion, and the probability of tank failure due to hydrogen explosion are discussed. Suggestions were made on the design, operation, and safety analysis of high-level waste tanks in China, which provided a reference for the safe development of high-level waste storage facilities in commercial reprocessing plants. |
