Abstract

The invention provides a spent fuel dry storage vertical storage module comprising a concrete foundation fixed on the ground; the foundation is provided with at least one containing space with a stepsurface, each containing space is used for detachably nesting and containing a corresponding cylinder body of a vertical silo and one end of the bottom of a spent fuel storage tank, and the foundationis provided with at least one ventilation opening communicating with an airflow channel; the ventilation opening is used for introducing outside air into the airflow channel to cool a medium in the spent fuel storage tank after the cylinder body of the vertical silo and the spent fuel storage tank are nested on the foundation, and exhausting air subjected to heat exchange to the outside through atop cover. According to the designed anti-tipping vertical silo with the stable structure, under the working condition of external natural event accidents, it can be guaranteed that the vertical siloand the spent fuel storage tank in the vertical silo are still in a vertical stable storage state, and the situation that the spent fuel storage tank is damaged and radioactive substance leakage is generated due to slippage, vibration and even tipping is avoided.

Description

technical field [0001] The invention relates to the field of dry storage of spent fuel in nuclear power plants, in particular to a vertical storage module for dry storage of spent fuel. Background technique [0002] Vertical concrete silos for dry storage of spent fuel (hereinafter referred to as "vertical concrete silos") are used to store and protect fuel storage tanks that seal spent fuel assemblies. As an important item for nuclear safety, vertical concrete silos perform nuclear safety functions during long-term storage, including: providing structural protection and radiation shielding for spent fuel storage tanks, and providing air convection channels to fully cool spent fuel storage tanks. [0003] At present, the whole structure of the vertical concrete silo widely and maturely used in the world can be divided into three parts: the top cover, the cylinder body and the base. The top cover is an independent structure, the top cover and the cylinder are connected by fl...
