© Published under licence by IOP Publishing Ltd.using the modernized high-temperature installation, the elastic characteristics and internal friction of the fuel rod shells were investigated in hot cell in order to update computer codes for WWER-1000 fuel rods. The elastic characteristics of the shell are analytically described and obtained a numerical shape factor of the first longitudinal frequency is calculated. There is description of new measuring units that provide data gathering by automatic or half-automatic mode. The elastic modulus and internal friction temperature dependences are determined by application of high-temperature modernized device that provides carrying out experiments at a temperature of 1160 K. Obtained effect could be interpreted by the crushing of the structure of the material.
