System for Monitoring Rupture of Steam Generator Tube in Nuclear Power Plant and Method for Monitoring Using the Same

摘要

The present invention relates to a system for monitoring tube leakage of a steam generator of a nuclear power plant, a measuring unit for measuring radioactive material leakage in a steam pipe connecting a steam generator and a turbine, whether or not the reactor is less than or equal to the low power of the nuclear power plant, and critical exceeding the nuclear power plant design standard A determination unit for determining whether an accident, and a calculation unit for calculating a radiation output value based on the measured value in the measurement unit, wherein when the determination unit determines that it is a serious accident, the measurement unit measures the total gamma radiation, the calculation unit It relates to a monitoring system that calculates the amount of secondary radioactive material leakage based on the total gamma radiation.
