摘要
Abstract
Aiming at the problems of safety injection operation characteristics and safety analysis of passive core makeup system(PCMS)under ocean conditions.A calculation program capable of simulating the safety injection process of PCMS in oceanic environments was created and preliminarily validated by extending the system analysis program ARSAC.Numerical simulations under various ocean conditions were conducted.Results reveal that the ad-ditional inertia force model and relevant program node model effectively predict the effects of ocean conditions on PCMS performance.Under fluctuating conditions,the safety injection flow rate periodically fluctuates,with its am-plitude influenced by the amplitude and period of fluctuation.Different rolling conditions result in significant differ-ences in additional inertial forces formed,leading to distinct fluctuation characteristics of the flow rate.Tilted work-ing conditions alter the height difference between the hot and cold ends of the PCMS,thereby affecting the safety injection flow rate.These findings offer valuable insights for the design and analysis of passive systems operating under oceanic conditions.关键词
