A wall structure for protecting spent fuel pools

Abstract

The invention relates to a wall structure for protecting a spent fuel pool. The periphery of the spent fuel pool (1) is provided with an auxiliary well (2) connected thereto for loading or cleaning spent fuel. The wall structure The walls include the wall (1‑1) forming the spent fuel pool (1) and the wall (2‑1) forming the auxiliary well (2), and the wall (1‑1) forming the spent fuel pool (1) Together with the wall (2‑1) forming the auxiliary well (2), they form a double-wall tooth-shaped occlusal structure. (2) There are toothed gaps of equal width between the body of walls (2-1). The wall structure provided by the present invention is simple and easy to construct, and the wall structure can effectively reduce the impact on the structure of the spent fuel pool caused by the vertical impact in the auxiliary well adjacent to the spent fuel pool, and at the same time meet the seismic requirements .

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a wall structure for protecting spent fuel pools. Background technique [0002] Before the spent fuel in the fuel plant of a nuclear power plant is transported to the plant, the spent fuel is first packed in a spent fuel container, transported out of the loading well by a crane, and then transported into the cleaning well to clean the container. The container is filled with spent fuel and weighs 130 tons. During the whole operation, the spent fuel container may fall to the floor of the loading well or cleaning well. Although the floor is designed with vibration-damping materials to reduce damage to the floor, due to The wall of the loading well and cleaning well is connected to the wall of the adjacent spent fuel pool, and the huge impact caused by the drop may affect the wall structure of the spent fuel pool, and even affect the normal operation of the pr...
