Information processing method of loop voltage stabilizer in nuclear power plant and checking method

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.
