Abstract

Abstract

During the power changing process in the nuclear power plant,in order to control the power distribution along the axial direction and to compensate the dynamic reactivity,the boron concentration has to be adjusted,besides the adjustment of the control rods.This paper established a dilution and boration model by using SIMULINK to forecast the speed and the amount of dilution or boronation during power changing process.It also compared the forecast value with the actual value in Qinshan phase II and maximum relative error is percent 5.2.
