Summary:Based on the nuclear instrument systems of units 5 and 6 (HPR1000) of Fuqing nuclear power plant, the calculation model of reactor nuclear instrument system is established and integrated into a full scope simulation machine by using two groups and three dimensional real-time neutron dynamic simulation and decay power calculation model. The established simulation system has been tested and verified by selecting source range, intermediate range, power range channel performance, control rod failure response and typical operating modes of turbine trip. The results show that the neutron flux change rate can reflect the core running state accurately in real time, and the nuclear instrument system can precisely simulate the related equipment states and the operating parameters, and verify the accuracy of the calculation model. In this case, the simulation degree, performance and system logic control could satisfy the training requirements of full scope simulator, thus can be widely used in the development and training of full scope simulator of nuclear power plant.
