ABSTRACT

Fuel elements (FE) with dispersed U-Mo fuel and Al matrix were tested in the research reactor IVV-2M. At a certain value of fuel burn up gas pores formed and united with test time leading to a formation of defects as extended gas cavities and ruptures in a fuel meat and pillowing of FE claddings. The moment the pores start to form and unite with the ruptures in the fuel meat is very difficult to fix while measuring their sizes even in plate FE. Since this formation is very important for the analysis of U-Mo fuel behavior under different operation conditions and for working out the measures to extend the operation life of the FE with U-Mo fuel relevant to high values of burn up. A gas pores form changing with burn up and changes of a thickness of an (U,Mo)Alx layer near the pores were analyzed and the method to determine the moment of the gas pore formation and ruptures of the fuel meat was suggested.
