Buckling Analysis of Sodium to Sodium Heat Exchanger Tubes

Abstract:

Sodium to sodium heat exchanger tubes are small in diameter, long and thin. These tubes are supported at intermediate locations and subjected to compressive and tensile loading during reactor operation. Structural mechanics analyses of a 2-D axi-symmetric model of heat exchanger was performed to estimate the load sharing in these tubes during reactor operation on finite element software ABAQUS. Since the tubes are suppoted at intermediate locations, a 3D model of full tube with intermediate support was made to calculate the critical buckling load and buckling modes. In this paper, structure analysis of heat exchanger and load sharing in tubes, critical load for tube and buckling modes in the tube, and design check of tubes under compression are covered. Tubes which are under compression are checked for buckling and found within the design limit.
