Abstract:
Seismic Margin Assessment was used to analyze the safety of nuclear power plant under the seismic of beyond design basis accident.The major failure modal of the refueling water storage tank is the failure of the anchor bolt in the method of EPRI SMA.Firstly,the seismic response was analyzed for the tank and the water.Secondly,the capacity is evaluated for the compressive buckling of the tank shell and the bolt hold-Down.Lastly,the Seismic Margin Earthquake was achieved with the assessment of overturning moment capacity and the sliding capacity.
