| 中文摘要: |
| AP1000先进反应堆采用了直接安注方式注入常温应急冷却水，导致反应堆压力容器（RPV）遭受严重的承压热冲击（PTS）.本文基于CFD程序ANSYS-CFX采用流固共轭传热方式，对不同工况下PRV直接安注接管（DVI-Nozzle）温度瞬态进行了数值模拟.计算结果表明：在不同工况下，DVI-Nozzle区域均经历较大幅度的温度阶跃，影响反应堆压力容器的安全性。 |

| The reactor pressure vessel （RPV） suffers from serious pressurized thermal shock （PTS） which is caused by the cold safety injection fluid direct into RPV downcomer in AP1000.In this paper,the Transient States of Temperature of RPV direct vessel injection nozzle（DVI-Nozzle） in AP1000 under the different operating conditions has been investigated using computational fluid dynamics （CFD） code ANSYS-CFX.Results show that the DVI-Nozzle experiences a large step change in temperature in each operating condition which causes the strong effect on the safety of RPV. |
