Abstract

The invention provides a control method and system of a material loading and refuelling device. First data, second data, third data and fourth data can be loaded in an upper computer of the material loading and refuelling device; and with configuration of corresponding interfaces, fusion with the original upper computer control system is realized, so that data management of a fuel assembly can be realized and the correctness and efficiency of the operation of the material loading and refuelling device can be improved. According to the first, second, third, and fourth data, the upper computer control system of the material loading and refuelling device can obtain data among the first, second, third, and fourth data by preset data interfaces or change the data among the first, second, third, and fourth data, so that the control system of the material loading and refuelling device can have the automatic completion function.

Description

technical field [0001] The invention relates to a control method and system for refueling equipment. Background technique [0002] The fuel loading and refueling equipment in nuclear power plants is the equipment used in the nuclear power plant shutdown and refueling process. Since the operating object of this type of equipment - fuel assemblies are highly radioactive, in order to ensure the safety of operators, all operations on fuel assemblies Both must be done in water deep enough to assure radiation shielding of the fuel assemblies. [0003] Most PWR fuel assemblies are stored in two places: in the core where the nuclear reaction takes place, and in the spent fuel pool where the radioactive fuel assemblies are stored. The two placement points are generally not in the same factory building, and need to be transferred by corresponding equipment. [0004] During the shutdown refueling process, the fuel assemblies need to be transferred between the core and the spent fuel ...
