Lab-scale fuel fabrication facility

A lab-scale fuel fabrication plant of several kilograms/year capacity is described. Zoning of the different activities along with a layout of the machinery and equipment are shown. A comprehensive description of the equipment is also given. The chemical processes associated with the production include precipitation (AUC process), followed by filtration, calcination, pelletization, sintering and grinding. A description of the fabrication of fuel pins (50 cm long) of uranium dioxide pellets, cladded in zircaloy tubing, is also included. The QC procedures associated with all stages in the plant are also indicated. Future plans for irradiation, post irradiation examination, and reporting of the fuel behaviour are also discussed
