As the molten salt fuel flows in the primary loop system of Liquid Molten Salt Reactor (LMSR), the core outlet fuel temperature can effectively characterize the core operation state. In this paper, a control strategy of the core outlet fuel temperature is designed based on the load power required. First, a nonlinear model of LMSR core is built by the lumped parameter method. Then, according to the relationship between the core outlet fuel temperature and the load power required, the control strategy of LMSR core outlet fuel temperature is established. The PID controller and the fuzzy PID contr...
