A nuclear reactor protection system, a nuclear reactor sensor, and a monitoring method of the nuclear reactor are provided to directly monitor a power distribution inside a core by compensating for a gamma ray sensitivity with respect to a gamma ray generated from a nuclear waste. A nuclear reactor protection system includes plural in-core gamma rays sensors(16,18,20), at least one in-core neutron sensors(22,24,26,28,30,32), and a reference power distribution controller. The in-core neutron sensors are arranged to correspond to the gamma ray sensors. The reference power distribution controller directly calculates the power distribution over the core by using the signals, which are generated in the gamma ray sensors and the neutron sensors. The nuclear reactor protection system further includes a core inlet hole temperature sensor, a core outlet hole temperature sensor, a refrigerant flow rate detector, and a refrigerant enthalpy variation calculator. |
