The finite-element models of the fuel assemblies UTVS, TVS-2 (designed by OKB «GIDROPRESS») and TVSA (designed by «AFRIKANTOV OKBM», N. Novgorod) were created by ANSYS code. The structure’s eigene frequencies and oscillation modes were determined. The computation of the structure’s response to seismic loads was based on the linearspectral method. The comparative analysis of the stressstrained states was fulfilled. The features of the structure under consideration were discovered.
