AbstractHumans looking for affordable energies and sufficient alternative for fossil fuels fordecades Growing need for energy produce more electrical energy transport and manyother needs that all of them are associated to electrical energy forced human to developnuclear energy as more as possible Scientist s estimation of extractable uranium frommines around the world shows that these resources of uranium are being depleted rapidly One of these fuels which exists much more than uranium around the world is thorium Inthis work production methods of thorium uranium pellet have been investigated and thisfuel has been produced for first time in IRAN In this work production method is powderyand addition of uranium has been done by saturation method This method because ofusing uranium 233 is hazardous has been presented under harsh condition Saturationmethod has been done by using uranium nitrate solution Then the pellets were placed inreducing furnace for final sintering Effect of various additives in the pellets exertingpressure in raw pellets and residence time of pellets in furnace are the cases that have beenstudied XRF XRD ICP BET and density test have been done on powder and finalproduced pellet and results have been compared with other researches The pellet withdextrin was destruction during impregnation The pellets with PEG showed good results inimpregnation technique The final density of the pellet was in the range of 90 95 of thetheoretical density Uranium concentrations in the pellet after impregnation obtainedaround 8 in ICP test and uranium titration The characterization of the sintered pelletswas made by optical microscopy scanning electron microscopy SEM The grainstructure of pellet with MgO was uniform with suitable porosity The pellet with PEGpolymer showed uniform morphology with microscopy fracture Keywords Uranium Thorium Saturation Pellet Uranium nitrate Nuclear energy Fuelcycle
