Stress and Buckling Analyses of Multitube, Vapor-Anode, Nb-1Zr/C-103 AMTEC Cells

Linearstressand buckling analysesofNb-1Zr/C-103 AMTECcells, mounted in a radioisotope generatorcone guration, are performed using e nite element analysis software. The stress analyses indicated that the total induced VonMisesstressesinthestructuralsupportmembersofthecellswillnotexceed86%ofthetemperature-dependent yield stresses of their respective materials. The buckling analyses indicated the need to add ribs to reinforce the cell wall and to decrease the pressure of the inert cover gas present in the generator during launch to 125 kPa. The total mass of the ribbed Nb-1Zr/C-103 cell is 171.5 g, and its specie c mass at the predicted maximum electric power of 8.0 W e is 21.3 g/We.
