Abstract

The application relates to an information processing method of a loop voltage stabilizer in a nuclear power plant and a checking method. The information processing method comprises the following steps: determining a corresponding relation between the liquid-level rising rate of a pressure releasing box and the loop leakage rate according to the structural relation between the liquid-level height during normal operation of the pressure releasing box and the pressure releasing box, and converting the liquid-level rising rate of the current pressure releasing tank into a value with the same unit as the loop leakage rate according to the corresponding relation; and according to the corresponding relation, establishing a matching relation of a processing plan for the liquid-level rising rate of the pressure releasing box and the loop leakage rate. The information processing method and the checking method have the advantages that the liquid-level rising rate is converted into the existing standard loop leakage rate, the problem that no standard exists for liquid-level rise of the pressure releasing box in the nuclear power plant in a long term is solved; by the establishment of the matching relation of the processing plan for the liquid-level rising rate of the pressure releasing box and the loop leakage rate, the problem of no intervention means of the liquid-level rise of the pressure releasing box in the nuclear power plant in a long term is solved, so that unnecessary disassembly and maintenance of valves are reduced and further the exposure dose to workers and radioactive wastes are reduced.

Description

technical field [0001] This application relates to the field of nuclear power technology, in particular to an information processing method suitable for the primary circuit regulator system of a pressurized water reactor nuclear power plant, and a method for controlling the liquid level rise rate of the primary circuit regulator pressure relief tank of a pressurized water reactor nuclear power plant. Fast troubleshooting method. Background technique [0002] A nuclear power plant is a power plant that uses the energy released by nuclear fission (Nuclear Fission) or nuclear fusion (Nuclear Fusion) reactions to generate electricity. In principle, nuclear power plants realize the energy conversion of nuclear energy-thermal energy-electric energy. In terms of equipment, the reactors and steam generators of nuclear power plants play a role equivalent to the fossil fuels and boilers of thermal power plants. Energy conversion in nuclear power plants takes place by means of three ...
