摘要：

"Cask immersion" is generally used in domestic nuclear power plants to deliver spent fuel, thus the risk of spent fuel cask dropping accident cannot be completely eliminated. The radioactive consequences of spent fuel cask dropping accident are analyzed and calculated, and how to ensure the integrity of the cask after dropping or how to contain radioactive materials after the cask integrity is broken is analyzed and studied. A series of improvement measures are put forward to alleviate the consequences of spent fuel ccask dropping, so as to reduce the risk of over-limit release of radioactive materials, which have positive guiding significance for improving the safety of spent fuel hoisting operation in nuclear power plants. © 2024 Atomic Energy Press.
