Abstract

The invention discloses a spent fuel dry-type storage device which comprises a spent fuel storage tank, a support and an outer module, wherein the spent fuel storage tank is mounted in the outer module in a sleeved mode, a shielding top cover is arranged on the top of the outer module, the shielding top cover is connected with the outer module is a sealed mode, the support is arranged at the bottom and on the side wall between the spent fuel storage tank and the outer module and used for supporting the spent fuel storage tank to enable a cavity between the spent fuel storage tank and the outer module to be formed, and an air inlet channel and an air outlet channel are arranged on the outer module. According to the spent fuel dry-type storage device, radioactivity shielding for the spent fuel storage tank can be achieved, waste heat of the spent fuel tank is discharged to the external environment through a natural ventilation mode, a fan, a water pump and other power equipment are not needed to be utilized, not only can energy be saved and is daily maintenance reduced, but also inherent safety is provided, and safety of a spent fuel storage tank natural ventilation cooling system is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of spent fuel storage of nuclear power plants, in particular to a spent fuel dry storage device. Background technique [0002] Nuclear power plants provide 17% of the world's electricity supply and are one of the indispensable energy sources. However, nuclear power plants have their own problems that limit their development, such as the safety of nuclear power and the storage and disposal of spent fuel. After the Fukushima nuclear accident in Japan, the inherent safety of nuclear power has been widely valued, and the development of safe and reliable spent fuel storage devices is of great significance to the safe operation and sustainable development of nuclear power. [0003] At present, many pressurized water reactor nuclear power plants have been built in my country. The main technical route for nuclear power development in the future will still be pressurized water reactors. High-temperature reactor nuclear power p...
