Embodiment 1

[0040] In Embodiment 1, a method for real-time monitoring of the pressure fluctuation of the coolant in the main circuit is provided. For the principle diagram of monitoring the pressure fluctuation of the coolant in the main circuit of the pressurized water reactor, see the attached figure 1 , the flow chart of the PWR main circuit coolant pressure fluctuation monitoring system is shown in the appendix figure 2 .

[0041] The monitoring principle of coolant pressure fluctuation in the main circuit of PWR is as attached figure 1The high temperature and radiation resistant pressure pulsation sensor is installed on the wall of the main reactor pipe to detect the pressure fluctuation of the coolant in the main pipe and generate a charge signal representing the pressure fluctuation. The charge signal is transmitted to the charge converter by a high temperature and radiation resistant hard cable Amplify and convert to a low-impedance voltage signal. The power adapter provides the...

Abstract

The invention discloses a method for monitoring the pressure fluctuation of main loop coolant in real time. The method includes the steps of firstly, a sensor is used to detect the pressure fluctuation of the coolant in a reactor main pipeline; secondly, a charge signal is transmitted to a charge converter for amplification and is converted into a low-impedance voltage signal; thirdly, a pressure fluctuation signal is transmitted to a pressure fluctuation conditioning module; fourthly, the pressure fluctuation conditioning module conditions the signal, a synchronous collecting card collects the conditioned signal in real time, and data transmission with an analyzing processor is achieved through PXI bus; fifthly, the analyzing processor analyzes the collected data to obtain abnormal pressure fluctuation so as to achieve management of a pressure fluctuation database. By the method, the pressure fluctuation of the main loop coolant can be effectively monitored in real time, the monitoring data can be analyzed and calculated, and the monitoring data can be managed conveniently.

Description

technical field [0001] The invention relates to the field of nuclear power equipment research, in particular to a method for real-time monitoring of main loop coolant pressure fluctuations. Background technique [0002] A pressurized water reactor nuclear power plant consists of a pressurized water reactor, reactor coolant system, circulating water system, generator, power transmission and distribution system and its auxiliary systems. The heat released by the fission of the pressurized water reactor core is taken out by the reactor coolant system and transferred to the circulating water system for power generation. The working medium of the reactor coolant system is water. When the nuclear power unit (the current domestic nuclear power plant in service) is running at full power, the coolant pressure in the main circuit is generally 15.5MPa. [0003] The pressure of the coolant in the main circuit system of the nuclear power plant is regulated by a voltage regulator. Genera...
