Problems solved by technology

If the edge of the existing storage rack is cut flat, it is easy to fall into it and the positioning is unstable; if the anti-drop anti-hook is set on the outer edge after cutting flat, it is not easy to insert smoothly because the gap between the adjacent cells is small, and the operation is difficult

Abstract

The invention relates to a burnable poison storage rack. The storage rack is arranged in a spent fuel framework and comprises a supporting plate (1), wherein the supporting plate (1) is of a square structure; a square hole (6) through which a fuel assembly passes is formed in the central position of the supporting plate (1); supporting angle iron (3) is arranged at each of four corners of the lower surface of the supporting plate (1); guide plates (4) are arranged among the four pieces of supporting angle iron (3); and convex blocks (7) or grooves are arranged on or formed in the two sides of the supporting plate (1), respectively. According to the storage rack provided by the invention, a large spent fuel storage space can be saved and reliable positioning and supporting functions can be achieved.

Description

technical field [0001] The invention belongs to the field of substance storage, and in particular relates to a storage rack for combustible poisons. Background technique [0002] At present, after the first refueling of a nuclear power plant, the burnable poisons are generally unloaded and placed in the burnable poison storage rack, and the burnable poison storage rack is placed in the spent fuel grid. The existing burnable poison storage rack has a large outer edge. See figure 1 . Therefore, every time a combustible poison storage rack is placed, it occupies 5-8 more spent fuel storage cells around it, and more than a dozen storage racks in the power station occupy more. In order to save space, there is also a storage rack at present: only two ends have flush overhanging edges, which saves a part, but each storage rack will still occupy three storage compartments. [0003] For example, the application number is CN 203607108 U, and the name is "burnable poison component s...
