Abstract EN
During operation in the sea the reactor natural circulation behaviors are affected by ship rolling motion.
The development of an analysis code and the natural circulation behaviors of a reactor simulator under rolling motion are described in this paper.
In the case of rolling motion, the primary coolant flow rates in the hot legs and heating channels oscillated periodically, and the amplitude of flow rate oscillation was in direct proportion to rolling amplitude, but in inverse proportion to rolling period.
The total mass flow rate also oscillated with half the rolling period, and the average total mass flow rate was less than that in steady state.
In the natural circulation under a rolling motion, the flow rate oscillations in the hot legs were controlled by the tangential force; however, the mass flow rate oscillations in the total natural circulation and the heating channels were a result of the combined action of the change of inclination angle, flow resistance, and the extra force arising from the rolling motion.
The extra tangential force brought about intense flow rate oscillations in the hot legs, which resulted in increasing total flow resistance; however the extra centrifugal force played a role in increasing thermal driving head.
