Process improvement of reconversion facilities

Technical Report:

Abstract

The project is for the development of recovery and reusing process of ammonium carbonate(AC) which is generated as a waste liquid from the reconversion facilities to reduce the manufacturing cost and the quantity of the waste liquid, and also for the development of the continuous fludized bed reaction process to promote the economics and safeties of the calcination and reduction process. In this second year report, measured the properties of AC solution and analyzed the AC concentration quantitatively. Examined the properties of AUC to investigate the properties of UO{sub 2} powder which was converted from AUC, prepared with AC solution. Designed and installed the 2 tons-U/year pilot plant. Experimented in powder properties to set up the range of operating conditions. Modeled CFB reactor to estimate the conversion of reactor and to analyze the change of fluorine concentration to carry out the defluorination reaction. Experimented out the optimum conditions of the major operating parameters : solid circulation rate, gas velocity, solid holdup and initial inventory in cold bed to get the referential design data for hot bed.
