| Summary: | A self-developed program was used to study the thermal-hydraulic behavior of an integral type reactor under heaving condition. Comparison of calculated results with the data of experiments performed on a natural circulation loop designed with reference to an integral type reactor of Tsinghua University in inclination, heaving, and rolling motions was carried out. Characteristics of natural circulation in heaving motion and effect of motion parameters on natural circulation were investigated. Results indicated that: (1) long-period heaving motion would lead to more significant influence than inclination and rolling motion; (2) it was an alternating force field which consisted of gravity and an additional force that decided the flow temperature and density difference of natural circulation; (3) effect of strength k and cycle T of heaving motion on flow fluctuation of natural circulation and condensate depression of heating section outlet was performed. |
