Seismic Analysis and Stress Evaluation of Horizontal Oil Storage Tank in Nuclear Power Plant
The horizontal oil storage tank represents a crucial component of the infrastructure of nuclear power plants,serving to store fuel for emergency diesel generating sets.In the seismic calculation and analysis,it is necessary to consider the impact of the shaking effect of the liquid in the storage tank on the equipment.The moving fluid pressure of liquid shaking was analyzed and calculated according to Housner theory,and a tank model was established by the finite element software ABAQUS for a further seismic analysis and calculation.For the equipment,the load and limitation in use,the calculation method of moving fluid pressure of liquid shaking were introduced.The stress response under seismic load was calculated by using the response spectrum method,and the stress under different loads were checked and evaluated according to relevant standard specifications.The results of the calculations demonstrate that the structural strength of the horizontal oil storage tank meets the requirements of the relevant seismic code and ensures the structural integrity and reliability under seismic conditions.This provides a reference basis for the optimal design and seismic assessment of horizontal oil storage tanks,and accumulates experience for further mastering the seismic analysis method of horizontal oil storage tanks,which is of great significance in ensuring the reliable operation of nuclear power plant equipment.
