This paper analyses the count rate of the ex-core source-range detector for Unit 4, M310 Pressurized Water Reactor (PWR), at Fujian Fuqing Nuclear Power Co., Ltd (FQNPC). The analysis encompasses power states during Cycle 1 startup and Cycle 3 fuel unloading. The analytical process involves analysing the count rate of the source-range detector, simulating secondary neutron source intensity and calculating nuclide information and neutron source intensity of irradiated fuel assemblies, etc. The maximum error between the theoretically calculated and measured count rate of the source-range detector is found to be 8.318%, which confirms the accuracy and validity of the count rate analysis method applied to the ex-core source-range detector for M310.
