Study on the Seismic Responses of an Experimental LMFBR including Fluid-Structure Interaction

摘要

A LMFBR usually contains a huge volume of liquid sodium as reactor coolant. Since most reactor components arernsubmerged in the sodium coolant, the seismic-induced fluid-structure interaction is of great importance to the design ofrnreactor block. This paper presents the result of shaking table test of a scaled reactor block model and analysis for Chinarnexperimental LMFBR. Experimental and analyzed results contain (1) beam-type vibration frequency of the reactor block; (2)rnsloshing frequency of the sodium coolant; (3) wave heights of non-linear sloshing under seismic action. Several conclusionsrnare obtained.
