| Objective To study in depth the calculation principle and method of PIPESTRESS program, summarize the characteristics of the software, and propose viewpoints on how to better use finite element software to complete nuclear pipeline calculation to guide the subsequent pipeline calculation work. Methods PIPESTRESS software was used to calculate the stress of ACP1000 Residual Heat Removal System piping. Combined with RCC-M specification and the basic principle of piping analysis, the basic principle and specific application of PIPESTRESS were discussed and studied in depth from the aspects of piping model establishment, load definition and working condition combination, seismic analysis and stress evaluation of the calculation results. Then the design verification for PIPESTRESS was carried ont with the SYSPIPE software. The causes of errors were studied in depth. Results Although there were some factors affecting the results of verification, the results of the two kinds of software were very close. Conclusion PIPESTRESS program can be well qualified for the modeling, mechanical analysis and stress assessment of ACP1000 piping, and has good calculation accuracy. The research results can provide basis for the calculation of ACP1000 piping, and also have great reference value for the future application of PIPESTRESS program in new reactor. |
