Abstract

Abstract

In the structural integrity test of the containment, the deformation of the containment is mainly caused by the test pressure and is also influenced by the ambient temperature, solar radiation and other comprehensive factors. In order to improve the deformation measurement accuracy of the test and make reasonable corrections, this paper investigates the influence law of ambient temperature, solar radiation, radiation heat exchange and different thermal boundary condition application methods on the deformation of the containment through finite element simulation analysis.The results show that the displacement of containment varies approximately sinusoidal with the ambient temperature, and lags behind the ambient temperature by about 2 h, and when the effect of solar radiation is ignored, the vertical average displacement amplitude of the dome is reduced by about 49% and the horizontal radial average displacement amplitude of the barrel is reduced by about 21%, indicating that the ambient temperature and solar radiation are the main environmental factors affecting the deformation of the containment, and reasonable corrections should be made to the deformation measurement results during the structural integrity test of the containment. Radiative heat exchange is a secondary environmental factor affecting the deformation of the containment structure, and it is recommended to consider the influence of this factor in order to guarantee the simulation accuracy. The containment deformation is almost the same when different thermal boundary condition application methods are used.
