For a basis of the second technique of definition a crack growth resistance of the fuel covers from alloy Zr-1%Nb the technique which uses an eccentric tension for loading a fuel cover with specially created two sharp cuts has been chosen and the moment, a beginning of motion a crack is defined by the strain gauge transducer of disclosing of a crack . The instruments for carrying out of tests for an eccentric tension of thin-walled fuel tubes and modernisation of the measuring channel of the test bed which allows with application strain gage transducer of disclosing of a crack to register loading and time the start of motion a crack have been described. There are begun researches on a substantiation of applicability of experimental and calculation procedures of this technique for definition of crack growth resistance the fuel covers of the Ukrainian manufacture. With use of the developed techniques comparative tests of characteristics crack growth resistance thin-walled the fuel tubes from zirconium materials of the Ukrainian manufacture are conducted.
