CP1400双乏燃料贮存格架地震条件下流固耦合试验研究
Experimental Study on Fluid-structure Interaction under Earthquake Condition of CAP1400 Double Spent Fuel Storage Rack
摘要
Abstract
CAP1400 is a new type of reactor developed independently in China,and the spent fuel storage racks stand freely in the spent fuel pool of CAP1400 reactor.Water can flow through the channels between the storage cells,while water is also found in the gap betw een the rack and rack,the rack and w all.In the case of earthquakes,due to the non-linearity of the fluid-structure interaction between the rack and water,it is difficult to calculate accurately with the software.In order to accurately investigate the charac-teristics of fluid-structure interaction,the experiment model of the spent fuel storage racks and the tank was established.The friction coefficient between the racks and the tank was measured by sweeping frequency test.At the same time,the influence of the gap size betw een the rack and rack on the sliding phenomenon and the fluid pressure w as studied.The friction coefficient between the rack and the tank was obtained by analy-zing the test results.Moreover,the larger the gap between the rack and rack is,the smaller the fluid pressure is,but the gap size has no obvious effect on the sliding phe-nomenon.The results can provide reference for design of CAP1400 spent fuel storage rack.关键词
