Abstract
It is very important for instruments and devices in the main vessel to remain the ability to work normally under seismic events.This paper conducts a shaking table test on the inductive sodium liquid level meter of the main vessel of the reactor.A steel frame with big stiffness enough is constructed to meet the demand of required response spectrum on the boundary condition.White noise,5 Operation Basis Earthquake(SL1)level tri-axial orthogonal seismic motions and 1 Safe Shutdown Earthquake(SL2)level tri-axial orthogonal seismic motion are applied successively.The results reveal that the natural frequency is 6 Hz in horizontal direction and 28.25 Hz in vertical direction,the frame can provide enough stiffness.The TRS(test response spectrum)can envolop the design response spectrum at the input area.Over the full test process,the monitoring device show that the liquid level meter can work in regular use and there is no damage occurs on the liquid level meter.关键词
