Experimental Study of Upper Plenum Entrainment in AP1000

  • 摘要: 为还原AP1000中上腔室夹带过程,以AP1000为原型按1∶5.6的模化比例建立了试验回路,研究不同蒸汽流量和压力容器液位下上腔室夹带的夹带率。结果表明:蒸汽流量对夹带率的影响很小,夹带率随压力容器液位的升高而增大;在较低液位,夹带率保持稳定,加入堆内构件后,上腔室夹带明显增强。

     

    Abstract: The test loop in the scaled ratio 1∶5.6 was constructed to repeat the process of upper plenum entrainment in AP1000. The upper plenum entrainment rate in different steam flow rates and different liquid levels of the pressure vessel was studied. The results indicate that the entrainment rate increases with the liquid level in the vessel and is affected by the steam flow rate weakly. The entrainment rate remains stable at lower liquid level. The upper plenum entrainment strengthens significantly with the insertion of the reactor internals.
