Abstract

The invention provides an inflation and drainage device for a spent fuel storage-transport vessel. The device comprises a cylinder, wherein a first cover plate and a second cover plate are arranged atupper and lower ends of the cylinder; a shielding compensation plug and an inflation check valve structure are arranged at the air inlet of the first cover plate; and a draining hole and a draining valve structure are arranged close to the bottom of the cylinder. When the device is used, a spent fuel storage-transport vessel is inflated and drained by adopting the shielding compensation plug andinflation check valve structure and the draining hole and draining valve structure. The inflation and drainage device has the advantages of practicality, safety and reliability.

Description

technical field [0001] The invention relates to a nuclear container, in particular to an inflation and drainage device for a spent fuel storage and transportation container. Background technique [0002] Fuel assemblies in nuclear power plants need to be taken out of the reactor after they reach the burn-up depth. Because they are rich in radioactive substances, they are highly harmful. If they are not handled properly, they will cause serious environmental hazards and loss of life and property. The first step in the processing of spent fuel is usually to store it in the nearby nuclear power plant's boron water pool, where it needs to be kept for several years to cool it down. [0003] However, due to the continuous generation of spent fuel and the limited storage capacity of boron pools in nuclear power plants, it is necessary to transfer the spent fuel out of the pool in time to replace the storage location or enter reprocessing. However, my country's nuclear power constr...
