Accuracy Computation and Software Implementation of CPR1000 Over-temperature and Over-power Protection Channel

In order to define the setting points of protection parameters in the reactor protection system, the accuracy of the parameter measuring and processing should be taken into consideration. The accuracy computations of over-temperature and over-power protection channel were analyzed in this paper, and the function and class structure design were completed. Finally, The accuracy computing software with friendly user interface was completed through C++ language. The calculation methods and software are used in CPR1000 and related improvement projects.
