Electron Probe Microanalysis of Minor Actinide Bearing Fuels Studied Within the FUTURIX-FTA International Collaboration: (pu0.8am0.2)o2+86 Vol. % Mo and (pu0.23am0.25zr0.52)o2+60 Vol. % Mo

The purpose of the FUTURIX-FTA (FUels for Transmutation of transURanium elements in phenIX) international irradiation program was to demonstrate the feasibility of burning minor actinides in dedicated reactors including Accelerator Driven Systems (ADS). The experiment also addressed the technical feasibility of transmuting minor actinides in fast neutron reactors from the fuel behaviour point of view. The study was carried out jointly by the US Department of Energy (DOE), the Joint Research Centre (JRC), the Japan Atomic Energy Agency (JAEA), and the Commissariat à l'énergie atomique et aux énergies alternatives (CEA). The advantage of this program was that eight different fuel compositions were irradiated at the same time under the same conditions in the Phénix reactor, France, and should have yielded comparable data.
