Abstrakt:	The effect of a humid nitrogen atmosphere with an oxygen content of 0.08, 0.48, 1.30 vol % and a temperature of 300°С on the change in the structure of the RBMK-1000 fuel composition vs. the size of the defect in the fuel cladding was investigated. It was demonstrated that in the case of fuel cladding damage with an area of more than 0.8 mm2, SNF storage in a nitrogen atmosphere with an oxygen content of more than 0.5 vol % at a temperature of 300°C brings about a rather rapid oxidation of the fuel composition to U3O8. Thus, dry storage of SNF should be carried out without access to oxygen. [ABSTRACT FROM AUTHOR]
