Abstract
The preferred processes for converting uranyl nitrate solutions into UO2 for the fabrication of nuclear fuel pellets all involve the thermal decomposition of solid compounds into UO3 without melting. Criteria for comparisons are given and used to compare eight conversion processes. Costs for the conversion processes are estimated to be 60 to 108% of the costs for the most commonly used ammonium diuranate precipitation/calcination process.Keywords
