| Abstract: |
| 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. |
