An Overview of Natural Circulation Thermal-hydraulic Characteristics of a Marine Reactor under Rolling Motion

摘要：

Marine reactor would be influenced by ocean conditions such as rolling, incline and heaving which made system coolant fluctuate and changed the ability of natural circulation of the system. The paper summarizes the study of effect of rolling motion upon thermal-hydraulic characteristics of natural circulation, including the study of Japan and China. The result shows that rolling motion has some effects upon natural circulation, and the structure of the test facility would affect the experiment result. Generally, rolling motion would cause core flow rate oscillation and the amplitude of oscillation increases as rolling angle increase and rolling period decreases. The flow oscillation caused by rolling motion would overlap the density wave oscillation which made the system more instabie. Heat transfer in the core is enhanced by the rolling motion and the enhancement is thought to be caused by the internal flow due to rolling motion. The parameters of the current experiments have some differences with the actual condition of the marine reactor, so some further research should be done.
