| Abstract: |
| Objective To ensure that stress analyzing and evaluating of the RVD system could meet requirements of RCCM code and the RVD system could run properly. Methods Firstly, the effect of flexibility coefficient on evaluating different rank pipes of the model in different codes was analyzed. Then with the help of PIPSTRESS software, the first version of piping layout for the RVD piping system was analyzed and evaluated, and the causes of excessively high stress were analyzed. Considering the effect of flexibility coefficient, different adjustment methods was applied to different rank pipes, the stress of each loading case was depressed. Results The modified RVD piping system satisfied the RCCM code. Conclusion By analyzing and evaluating the RVD piping system, the way for solving similar problems was achieved; and the problems of the design of the piping system was summarized, which can be a guidance of piping system design of nuclear power plant. |
