Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0063] In addition, it should be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and...

Abstract

The invention belongs to the technical field of nuclear auxiliary cooling water for a mega-kilowatt nuclear power plant, and discloses a new grid connection device for capacity expansion of a spent fuel pool and a connection method thereof. Wherein, the connecting device includes a pair of grid bottom plates and a pair of grid frames, and also includes a connecting assembly for connecting two adjacent grid bottom plates, and the connecting assembly includes a connecting plate, which is respectively arranged on two sides of the connecting plate. The first positioning plate and the second positioning plate at the end, the temporary screws for installing the first positioning plate on the one grid bottom plate, and the final screws for installing the second positioning plate on the other grid bottom plate screw. Install the first positioning plate on the grid bottom plate by temporary screws, install the second positioning plate on the adjacent grid bottom plate by final screws, and connect the first positioning plate and the second positioning plate respectively by connecting plates , so as to realize the connection between two adjacent grids, ensuring the stability of the grids and preventing the grids from overturning during an earthquake.

Description

technical field [0001] The invention belongs to the technical field of nuclear auxiliary cooling water for mega-kilowatt nuclear power plants, and more specifically relates to a new grid connection device and connection method for expanding the capacity of spent fuel pools. Background technique [0002] Spent fuel is radiation-irradiated, used nuclear fuel produced by nuclear reactors in nuclear power plants. The nuclear fuel after the nuclear reactor reaction contains a large amount of radioactive elements, so it has a large amount of radioactivity. If it is not handled properly, it will seriously affect the environment and the health of people who come into contact with them. Therefore, the spent fuel after the nuclear reactor reaction of the nuclear power plant needs to be stored in the spent fuel pool for decades until its radioactivity is reduced enough to allow subsequent reprocessing of the spent fuel. With the increasing number of domestic nuclear power plants and t...
