METHOD FOR ESTIMATING THE CONCENTRATION IN A CHEMICAL ELEMENT IN THE PRIMARY COOLING LIQUID OF A NUCLEAR REACTOR

摘要

The method involves acquiring a magnitude representing a flow of injection of dilute solution e.g. pure water, a magnitude representing a flow of injection of concentrated solution, and a magnitude representing concentration of chemical element measured by a sensor in a cooling liquid of a nuclear reactor. Estimated value is calculated from the concentration of the chemical element in the cooling liquid based on the magnitudes, using a Kalman equation.
