Problems solved by technology
[0003] However, in the existing pressurized water reactors, fast reactors and other fields, no identification device is installed to automatically judge the component number for the plug-in operation and transportation process of the components, so it is very likely that the components will be damaged due to human error. Incorrect plugging and unplugging and transport errors, resulting in damage and even danger
[0004] In fast neutron nuclear reactors, a new component loader is generally used to transfer new components in the new fuel warehouse. The new component is in a closed dark environment and in a state of motion in the new component loader. This brings great benefits to the automatic identification of new component numbers Difficulty
The high temperature, high pressure, high radioactivity, strong corrosiveness and closed environment in the reactor core make it impossible to identify the component number in the core
The high radioactivity of depleted components also brings difficulties to the automatic identification of depleted component numbers

The invention discloses an identification system and an identification method for nuclear power station component codes, and the identification system comprises a needle type marking device which is set to form codes at the head of a new component; a new component loading machine arranged to transfer the new component with a code, wherein the new component loading machine comprises a guide pipe and a guide column, the new component is arranged in the guide pipe and moves relative to the guide column together with the guide pipe, the guide pipe is provided with a first open hole, and the guidecolumn is provided with a second open hole. The invention also comprises a recognition device and a polarized light source which are installed in the second open hole. The polarized light source can irradiate the code of the new component through the first open hole, the recognition device can recognize the code through the first open hole, and the second open hole has an inclination angle, so that the recognition device has an installation angle. The invention also comprises a camera device arranged to shoot the coded video of the spent component; an image processing device configured to decode an encoding in the encoded video; and a monitoring device.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of nuclear engineering, and in particular to an identification system and identification method for nuclear power plant component codes. Background technique [0002] Various components in a nuclear reactor are important components for maintaining chain reactions and reactor power control. All components have unique numbers, and the transfer and operation of components is very important. In order to ensure the correct operation of the components, it is necessary to identify the component numbers. [0003] However, in the existing pressurized water reactors, fast reactors and other fields, no identification device is installed to automatically judge the component number for the plug-in operation and transportation process of the components, so it is very likely that the components will be damaged due to human error. Incorrect plugging and unplugging and transportation errors can cau...
