Based on the Monte Carlo method,this thesis proposes a neutron sensitivity calculation model for the design and study of the performance of ex-core neutron detectors.Firstly,based on the physical principle of the detector,the influencing factors of neutron sensitivity are obtained.On this basis,the neutron field characteristics at the monitor holes are analyzed,and the neutron sensitivity calculation model is proposed.The calculation model is discussed to obtain the uncertainty analysis of the model.Finally,the model is verified,and the error between the calculated neutron sensitivity and the measured data is within the acceptable range,which verifies the feasibility of the model.
