摘要：
In the present paper, one proposes an equation of state allowing to reasonably describe the behavior of the xenon/krypton mixtures, in any proportion, confined in the form of nanoscale bubbles in the UO2 and MOX nuclear fuels. The temperature range covered by this equation lies between the room temperature and the fuel melting point. The equation of state, which was built based on molecular dynamics results obtained on a large density-composition-temperature range, could be easily implemented in the nuclear fuel performance codes.
