Abstract
The precision and efficiency of the measurement of control rod worth are of great importance to the safety and economy of nuclear power plants.During reactivity measurements,such as the dynamic control rod worth measurement,the background and neutron source have significant impact on the detectors,resulting in a significant error of the measured reactivity.Based on the point-reactor inverse kinetics equation,the background and neutron source were analyzed,and the reactivity and control rod worth were obtained by use of the data measured with the control rods being at static positions.Accordingly,a practical method was developed for the measurement of the total worth of control rods,which is free from the impact of background and neutron source,and tested on a zero power facility.It is shown by the test results that the method effectively eliminates the impact of background and neutron source and simplifies the offline calculation.The relative difference between the result of this method and that of the periodic method is below 1％.关键词
