METHOD FOR CONTROL OF THERMAL RESISTANCE OF HEAT-DRIVING ELEMENTS OF A NUCLEAR REACTOR

摘要

The method of controlling the thermal resistance of fuel elements of a nuclear reactor, which consists in measuring the flow rate and temperature of the coolant at the inlet and outlet of the fuel assembly, characterized in that, in order to increase reliability by continuously monitoring the fuel elements, the fluctuations of energy release in the fuel assembly calculate the output of the fuel assembly using a thermal model using measured values of the fluctuations of energy release, consumption and the temperature of the coolant at the input of the fuel assembly, determine the thermal resistance, coordinating with the help of the correction of the thermal model of the fuel assembly the calculated dependence of the temperature at the output of the fuel assembly with the measured one.
