A method is described for the determination of > 10 milligrains of boron in boron carbide-zirconium material clad with Zircaloy. The sample is refluxed in quartzware with concentrated hydrochloric acid plus 1:20 hydrofluoric acid. The acid insoluble residue is filtered, ashed, and fused with sodium carbonate. The melt is dissolved in hydrochloric acid, and adjusted with sodium hydroxide to precipitate any hydrolyzable elements which may interfere with the final boron titration. The boron in the HCl-HF soluble filtrate is separated from the bulk of the zirconium with a barium carbonate precipitation. The acid insobuble and acid soluble boron are then determined individually bv a potentiometric mannitol titration. (auth)
