Abstract

The invention discloses a vertical shaft storage system for spent fuel of nuclear power station, relating to the technical field of reactor engineering, wherein the system comprises a vertical shaft array, a cold wind unit, a hot wind unit, a vertical shaft top plate and a vertical shaft bottom plate, wherein the vertical shaft array includes multiple vertical shafts which are arranged between the vertical shaft top plate and the vertical shaft bottom plate; the cold wind unit is connected with the upper part of the vertical shaft array for inputting cold wind to the vertical shaft; the hot wind unit is also connected with the upper part of the vertical shaft array for exhausting the hot wind in the vertical shaft. The system stores the spent fuel in the vertical shaft, can store the spent fuel storage tank of high temperature gas-cooled reactor in the nuclear power station and also can store the spent fuel storage tank of pressurized water reactor and other nuclear power station, andalso is used in the common industry related fields.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a nuclear power plant spent fuel storage shaft system. Background technique [0002] At present, more than 400 reactors for power generation are operating in various countries in the world, most of which are pressurized water reactors and boiling water reactors. These nuclear power plants produce a large amount of spent fuel every year. Temporarily stored in the spent fuel pool for cooling for more than 5 years, and then can be transferred to the intermediate storage of spent fuel for storage, or transported to the reprocessing plant for reprocessing. [0003] Since some countries choose the intermediate storage route of spent fuel and do not reprocess spent fuel, countries around the world have developed a variety of intermediate storage facilities for spent fuel. For example, the United States has developed a concrete storage container, placing a spent fuel storage ...
