Control method and control system applied to cooling branch of spent fuel pool

Abstract

The invention belongs to the technical field of safety control of a million-kilowatt-class nuclear power plant, and provides a control method and control system applied to a cooling branch of a spentfuel water tank of the million-kilowatt-class nuclear power plant. The control method comprises the following steps of: collecting operating parameters of the cooling branch of the spent fuel water tank; transmitting the operating parameters to a computing information and control system, and analyzing by using the computing information and control system according to the operating parameters so asto obtain the operating state of the cooling branch of the spent fuel water tank; displaying the operating state of the cooling branch of the spent fuel water tank; and if the cooling branch of the spent fuel water tank has an operation failure, giving out a cooling branch warning signal. The control method and control system can monitor the operating state of the cooling branch of the spent fuelwater tank in real time, send fault warning information accordingly, greatly improve the safety of the cooling branch of the spent fuel water tank, and solve the problems that the cooling branch of the spent fuel water tank in a conventional technology has relatively low safety level, and a nuclear power unit has low power generation efficiency.

Description

technical field [0001] The invention belongs to the technical field of safety control of mega-kilowatt nuclear power plants, and in particular relates to a control method applied to the cooling branch of a spent fuel pool of a mega-kilowatt nuclear power plant and a control system applied to the cooling branch of a spent fuel pool of a mega-kilowatt nuclear power plant . Background technique [0002] With the increasing demand for electricity in modern industrial society, nuclear power has become an extremely important part of the society's power system. Therefore, the operation safety of nuclear power plants has an extremely important impact on the safety of electricity consumption in people's production and life; due to the The nuclear fission reaction of nuclear fuel is used to generate high-power nuclear power plants. Therefore, during the power generation process of nuclear power plants, nuclear power units will produce a large amount of spent fuel. These spent fuels ar...
