摘要：
The operational characteristics of passive residual heat removal system on the rolling apparatus were investigated experimentally. The effects of rolling motion upon main parameters of passive residual heat removal system were analyzed. The effects of gravity and additional pressure drop in rolling motion upon flow velocity were also investigated theoretically. In rolling motion, the fluctuating period of the main parameters is the same with that of rolling motion. The parameters' fluctuations become more significant as the rolling motion becoming more acute. The variation trends of average condensate flow and temperate are the same. The average I/O coolant temperature is different, but their fluctuating amplitudes are nearly the same. Steam pressure and condensate temperature do not oscillate in rolling motion. Additional pressure drop can cause the response of the flow velocity, but it does not effect upon the average flow velocity. The decreasing of average flow velocity is partly caused by the reduced average gravity pressure drop.
