Problems solved by technology

[0003] In the prior art, most of the inspection devices for fuel rods after irradiation are special tools, and the special tools and storage containers are independent of each other. The fuel rods are suspended by the fuel rod operating tools and moved to the special tools for inspection. The fuel rod operation tool is lifted and translated into the storage container. The whole operation is time-consuming and likely to increase the probability of release of radioactive substances in the fuel rod
In addition, most of the existing irradiated fuel rod storage containers are designed for simple temporary storage, and do not have the operation interface of fuel rod inspection tools and the long-term safe storage capacity of irradiated fuel rods in the fuel pool

Abstract

The invention relates to the technical field of fuel inspection and repair, in particular to a fuel rod inspection and storage device. The device comprises a storage rack, a storage pipe vertically supported in the storage rack and an inspection rack supported at the top end of the storage rack. An inspection space is formed between the inspection rack and the storage rack. The inspection rack is provided with an inspection hole and a storage hole for a fuel rod to pass through, a detection piece is installed in the inspection hole, and the storage hole and the storage pipe are coaxially arranged and communicated to form a storage channel. A fuel rod can be detected by the detection piece through the inspection hole and then reaches the inspection space for inspection, and the fuel rod after inspection can be stored in the storage pipe from the storage hole through the storage channel after exiting from the inspection space and the inspection hole. A fuel rod stored in the storage pipe can also be taken out of the storage channel and then enter the inspection hole and the inspection space for reinspection. The integrated design and operation of fuel rod inspection and storage are achieved, the fuel rod inspection and storage operation time can be shortened, and long-term storage of fuel rods is achieved.

Description

technical field [0001] The invention relates to the technical field of fuel inspection and repair, in particular to a fuel rod inspection and storage device. Background technique [0002] During the operation of nuclear power plants, the fuel rods are exposed to high temperature, high pressure and high radiation environment for a long time, coupled with the influence of foreign matter in the core, vibration, and water impact, they are prone to damage and leakage. After the assessment of the nuclear power plant, the suspected damaged fuel rods can be replaced with new ones to repair the fuel assembly. Fuel rods that are suspected of being damaged are taken out of the fuel assembly, and are stored in special containers after being confirmed by visual inspection and eddy current inspection. [0003] In the prior art, most of the inspection devices for fuel rods after irradiation are special tools, and the special tools and storage containers are independent of each other. The ...
