Nuclear power plant condenser leakage detection system

Abstract

The invention particularly relates to a nuclear power plant condenser leakage detection system which comprises a condenser leakage monitoring module, a condenser leakage judgment and response module and a condenser leakage calculation module. The condenser leakage monitoring module is used for monitoring the concentration of foreign ions in nuclear power plant equipment in real time and sending the concentration to the condenser leakage judgment and response module and the condenser leakage calculation module in real time. The condenser leakage judgment and response module is used for judging whether cold source leakage happens to a condenser or not in real time and taking corresponding measures. The condenser leakage calculation module is used for calculating the impurity ion concentration in the steam generator and the condenser cold source leakage rate in real time. According to the nuclear power plant condenser leakage detection system, condenser cold source leakage is monitored in the first time, correction action is adopted, impurities are prevented from entering a steam generator, and operation risks and economic losses caused by power reduction and even shutdown due to condenser leakage of a nuclear power plant are avoided.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant condenser leakage, in particular to a nuclear power plant condenser leakage detection system. Background technique [0002] It is an unavoidable problem that the leakage of the condenser will pollute the water quality of the secondary circuit. Leakage of the condenser will inevitably lead to unit state fluctuations, power reduction, or even shutdown. There have been incidents in China where the water quality of the secondary circuit was polluted by the leakage of the condenser, which eventually led to the shutdown of the nuclear power plant. A total of 84 condenser leaks occurred in a nuclear power plant in a certain country during the five years from 2008 to 2012, and the power loss was nearly 200 million kWh, which brought heavy economic losses to the power plant. This statistical data includes inland nuclear power plants that use fresh water as a cooling source. At present, domest...
