摘要：

Oscillations of a cantilevered rod - fuel element simulator - were experimentally studied in an annular channel with a longitudinal ascending fluid flow using an original sensor built on the basis of the electrical impedance method. The data on the trajectories of the rod axis movement and changes in amplitude and frequency of rod vibrations depending on the velocity of the axial fluid flow are given. The data on rod vibration obtained using the electrical impedance method and high-speed video recording are compared.
