Interim development report for secondary burning
The HTGR fuel reprocessing flowsheet consists of crushing the spent fuel elements to a size suitable for burning in a fluidized bed to remove excess graphite; separating, crushing, and reburning the fuel particles to remove the remainder of the burnable carbon; dissolution and separation of the particles from insoluble materials; and solvent extraction separation of the dissolved uranium and thorium. Burning the crushed fuel particles is accomplished in a secondary burner. This is a batch fluidized-bed reactor with in-vessel off-gas filtration. Process heat is provided by an induction heater. This report documents development work performed to date on the secondary burner. Analysis of the work is provided and recommendations are made for future applications in larger burners.
