A theoretical model describing the coupling of neutronics, thermohydraulics and fluidization in a fluidized bed nuclear reactor is presented. Simulations of operational transient conditions are performed, viz. a decrease of coolant flow rate and a change of coolant inlet temperature. These simulations show that the fuel temperature remains below the maximum allowable temperature of TRISO fuel, therefore ensuring a safe operational transient. The maximum reactivity is inherently limited and is rapidly compensated by the passive feedback mechanism.
