Abstract

Abstract

The response Matrix of assembly （or Node） to out-core chamber of a nuclear power plant is calculated by Monte Carlo Method （M.C.） and code. By means of which, the currents of each section of the chamber and the calibration coefficient are calculated. Therefore the theory in-core thermal power level P_r and axial offset ΔI are obtained. The theory results of different cycles and different Xe oscillation steps are compared the measured data. It shows that the numerical method is suitable for modeling out-core RPN system. The accuracy of calculation is sufficient for engineering precision.
