Abstrakt:	Conclusions A complex procedure has been developed for the study of gas release from nuclear fuel, including reactor measurements and post-reactor determination of the amount and composition of the gas medium in the fuel elements at room and elevated temperatures. In fuel elements with compact uranium dioxide (density 10.0–10.43 g/cm3), in addition to gaseous fission products and the helium introduced, Ar, H2, O2, CO, CO2, and N2 are present, and after irradiation their quantity exceeds the initial quantity, measured for unirradiated fuel elements, by a factor of several.
