摘要 1引言自从美国三哩岛事故和(前)苏联切尔诺贝利事故以来,科学家们努力改进反应堆的安全性。新一代轻水堆引人了固有安全的概念,其中的一个新概念就是使用自然循环来带走堆芯的热量[‘]。自然循环是依靠系统冷热流体间的密度差所形成的浮升力来驱动流体克服流动阻力?.. This paper studies density wave oscillation in a vertical upflow pipe of the two-phase natural circulation loop. The oscillation curves at different conditions are obtained. By means of plurality linear regression analysis of the experimental data, a stability criterion of the density wave oscillation under the low pressure two-phase natural circulation conditions is developed.The range of the experimental parameters as follow: system pressure P = 0.2 ~2.0MPa, mass flow rate G =265 ~2654 kg/m2s, inlet subcooling △Tsub = 5 ~ 40℃, heated power Q = 5 ~ 30 kW.
