| Abstract: |
| Objective To carry out seismic analysis for the degassing tower liquid cooler to ensure necessary safety function under the earthquake. Methods With FuQing 5/6 nuclear power station as an example, the finite element model of the degassing tower liquid cooler was established with software ANSYS, and the response spectrum method was adopted for seismic analysis and evaluation of the equipment. Results Through seismic analysis evaluation, the calculation process and characteristics of spectral analysis was learned and the weak area of equipment was found out. Therefore, the structure of the saddle was modified by increasing rib plate and wall thickness to make the equipment meet requirement of relevant code. Conclusion The structure of the saddle is modified to guarantee its functions and meet the needs of the practical engineering. |
