Current necessities of nuclear power plants have led to increase burn-up of the fuel during operation. In this context, some undesirable processes, such as a higher release of gaseous fission products, may occur. New UO2-based fuels are being develop

Chromium volatilization from Cr 2 O 3 powder and Cr 2 O 3 -doped UO 2 pellets during sintering in reducing atmospheres has been studied by thermogravimetry (TG) coupled with differential thermal analysis (DTA) up to 1700 °C. The sintering of Cr 2 O
