Popis:	Identification of a failed fuel subassembly due to the dry rupture of its fuel pin in Fast Breeder Test Reactor was accomplished from the measurement of the degree of burn-up of the fuel. In the present paper, a method for the measurement of krypton radionuclides ratios by means of gamma-ray spectrometry is suggested. The method has been applied both for determination of the degree of fuel burn-up through the analysis of fission gases released and identification of a problematic fuel subassembly that is responsible for the released gas. The burn-up of the failed fuel subassembly was found to be > 100 GWd/t which facilitated establishing the failed fuel subassembly with the dry rupture.
