This paper describes a preliminary analysis of the response of an accelerator-driven system during beam trip transients. The system addressed is a dedicated transmuter consisting of a lead-bismuth cooled 800-MWt subciritical core combined with a saturated steam turbine cycle. Transients of the primary coolant temperature, the water/steam temperature, the water/steam pressure, the turbine flow rate, and the electric power output were calculated using a simple network model. The result shows that a beam trip shorter than 380s requires no active control of the system, while a prolonged beam trip demands turbine and plant trips to preventing from failure of system components. The maximum temperature swing is 185℃ in lead-bismuth at 370s after the beam trip.
