Options for fuel cycle technology improvement have strongly regained attention lately with the revival of nuclear energy production interests and plans for next generation nuclear systems. Various fuel forms, geometries and production paths are being looked at. Within the FUJI collaboration program among Japan Atomic Energy Agency (JAEA, former JNC), Paul Scherrer Institute (PSI, Switzerland) and Nuclear Research and Consultancy Group (NRG, the Netherlands) the production paths of plutonium and neptunium mixed oxide- (sphere-pac- and vipac-) particle fuels (20 wt% Pu, 5 wt% Np and 75 wt% U) are tested as well as the initial sintering and power-to-melt behavior under simulated Fast Breeder Reactor (FBR) conditions. The various fuel forms were produced at PSI under the support of JNC, the irradiations were accomplished at High Flux Reactor (HFR) in Petten, the post irradiation examinations are being achieved mainly at NRG and the fuel modelling being performed at JNC and PSI. The present paper reviews mainly the project planning, fuel behaviour-pre-calculations and the fuel- and fuel segment-production. A short overview of the irradiation conditions and ceramographic post irradiation examination analyses is also given.
