Abstract:

The shielding door is the important protective equipment of AP1000 nuclear power station. When the plant is not in the operation, it is mainly subjected to its own gravity, wind load, impact load from the heavy projectile, temperature load from the fire disaster and the seismic load from the earthquake. Taking the shielding door as the research object and using the security shut-down earthquake load as the design seismic load, the anti-seismic performance of the shielding door is analyzed and evaluated under the seismic load, respectively by two methods: static method and response spectrum method. The results show that the whole structure of the shielding door can meet the requirement of ASME; Using the static method, the worst direction of the horizontal acceleration is the direction of the angle of 45o which is the angle between one horizontal acceleration and the X axis. Spectrum analysis results show that the vertical acceleration of response spectrum contribution to seismic load, the stress and displacement is very small; Calculating results of the two methods are close, but the static method is a bit conservative.
