Carbon Contained Ammonium Diuranate Gel Particles Preparation in Mid-process of High-temperature Gas-cooled Reactor Fuel Fabrication

다국어 초록 (Multilingual Abstract)

This study investigates the dispersibility of carbon in carbon contained ammoniumdiuranate (C-ADU) gel particles and the characteristics of C-ADU gel liquid droplets producedby the vibrating nozzle and integrated agingewashingedrying equipment. It wasnoted that the excellent stability of carbon dispersion was only observed in the C-ADU gelparticle that contained carbon black named CB 10. ADU gel liquid droplets containingcarbon particles with the excellent sphericity of approximately 1,950 mm were then obtainedusing an 80-100-Hz vibrating nozzle system. Dried C-ADU gel particles obtained bythe aging-washing-drying equipment were thermal decomposed until 500℃ at a rate of 1℃/min in an air or in 4% H2 gas atmosphere. The thermally decomposed C-ADU gelparticles showed 24% weight loss and a more complicated profile than that of ADU gelparticles.
