摘要
Abstract
In the present paper,the effects of rolling condition on the total loss of alternative power conditions are analyzed.The results show that,during the transient,the decay heat is removed by natural circulation of the primary loop and the PSHR system.Under the rolling condition,the primary natural circulation flow rate changes on a period of the rolling period.The larger the rolling frequency or amplitude,the flow rate fluctuation is more violent.The PSHR systems were started later than that under static condition.The more violent the rolling is,the later the PSHR is put into operation.The heat transfer is enhanced under the rolling condition,thus the decreasing rate of the RCS temperature is increased.The larger the rolling frequency or the amplitude is,the larger is the decreasing rate of the RCS temperature.关键词
