Marine nuclear power plant simulator

In this paper, a real time simulator of nuclear power plant for ship propulsion is described. The simulator is composed of a hybrid computer and an operating console. Simulated power plant is a 36 MWt PWR plant. Reactor kinetics, fuel temperature, primary coolant temperature, primary pressure, temperature and pressure of steam in the steam generator, steam flow, rotating speed of the propeller shaft, and various controlling system are simulated. Using this simulator, frequency response functions of the reactor power to the variation of reactivity and load were measured. (author)
