Abstract

The invention relates to a nuclear reactor spent fuel storage technology, in particular to a nuclear reactor spent fuel dry type storage house. A house body of the storage house is arranged in a factory; the top of the house body has a pound-shaped girder framework structure; a storage barrel is arranged in each vertical hole of a pound-shaped girder; a plurality of storage pipes are arranged in the storage barrel; each storage pipe is used for storing spent fuels; the storage barrels are poured with heavy concrete after being positioned, so the upper part of the storage house has an integrated structure and radioactive shielding function; the storage house is provided with an air exhaust cooling facility so as to keep refreshing the air in the house and keep a certain negative pressure and a proper temperature; and a heavy concrete shielding layer is arranged at the periphery of the whole storage house. The storage house is good in shock resistance, compact in structure, easy in operation, and low in running maintenance cost and whole production cost.

Description

technical field

[0001] The invention relates to nuclear reactor spent fuel storage technology, in particular to a nuclear reactor spent fuel dry storehouse. Background technique

[0002] Spent fuel storage facilities are used to store radioactive spent fuel after discharge from the reactor. Due to the adoption of various measures to resist the strong radioactive release of spent fuel and the large release of decay heat, the general structure is relatively large, and the design and construction quality requirements are high. It is also relatively high, and generally adopts two storage schemes of dry method and wet method. The storage method of reactor spent fuel at home and abroad mainly adopts wet storage method, but wet storage requires high-quality processing of fuel grids, strict manufacturing requirements for storage pools, high cost, and a set of water supply, cooling and treatment facilities. Not only the facilities are huge, Operation and maintenance costs are also h...
