| 中文摘要: |
| 目的 求解管道壁厚方向的温度分布。方法 采用PIPESTRESS程序，对某核电站化学和容积控制系统管道的某一瞬态温度曲线进行瞬态热分析。结果 得到管道7类关键区域的温度场和最不利的温度梯度ΔT1、ΔT2、Ta、Tb，并将该温度梯度数据与参考电站数据进行对比。结论 采用PIPESTRESS程序的结果满足工程需要。该工作不仅为管道疲劳分析提供了重要输入条件，其研究方法也为其他系统管道的热分析提供了重要参考。 |

| Objective To obtain the temperature distribution across the pipe thickness. Methods Transient thermal analysis of one transient temperature curve of RCV piping in one nuclear power plant was done by PIPESTRESS program. Results Temperature distribution and temperature gradients ?T1 and ?T2、Ta、Tb of 7 key areas of pipe were obtained. Also,the temperature grandients were compared to those of the reference power station. Conclusion The results obtained by PIPESTRESS can satisfy the engineering requirements. The investigation method can provide not only the input conditions of piping fatigue analysis, but also the reference of piping thermal analysis of other projects. |
