A method of reducing errors when calculating a shape annealing function (SAF) of an ex-core detector (70) of a nuclear power plant is provided. The method comprises 3-dimensionally modeling elements of the nuclear power plant comprising a nuclear reactor core (10), an ex-core detector (70) disposed in a nuclear reactor cavity (50), and nuclear reactor structures (20, 30, 40, 60) arranged between the nuclear reactor core (10) and the ex-core detector (70); predicting an arrival position for emitted neutrons, by using a Monte Carlo method when a neutron source arranged at the ex-core detector (70) and neutrons emitted towards the nuclear reactor core (10), the predicted arrival position indicating where the emitted neutron will arrive at the nuclear reactor core (10); and producing an SAF based on a correlation between the neutron source arranged at the ex-core detector (70) and the predicted arrival position of the neutrons. |
