Abstract

Primary water accident pump is an important part in the waste heat export of reactor, whose seismic performance will directly affect reactor safety shutdown and exuding of waste heat after the occurrence of major earthquakes. Under the condition of running, primary water accident pump of prototypes from earthquake simulation shaking table test is the most intuitive method to evaluate the seismic performance. This paper selects the steel wire rubber corrugated pipe connection with import and export of water pipe, use sand pile support rubber bellows with flexible constraints. Reasonable simulation of water pump in the process of the test is over load, at the same time primary water accident pump and circulating water tank in the test process of deformation coordination. In this paper, through selecting wire rubber bellows as in and out of the water pipes, use as constraint of rubber hose, sand guarantees the rationality of the boundary conditions in the process of experiment. Five OBE and one SSE earthquake simulation shaking table tests for the Primary Water Accident Pump were performed by using artificial seismic waves as the seismic inputs in normal running. According to time history curves of strain, the maximum structure responses of strain under the input of different artificial seismic waves were obtained ,and the structure was found in elastic state. The results show that the structural integrity and operating function of the Primary water accident pump are not changed during five OBE and one SSE tests; and the performance indexes of the Primary water accident pump remain consistent before and after seismic tests; the seismic performance of the Primary water accident pump can satisfy relevant technical requirements.
