Claim 1
Independent Claim
113 words
A METHOD OF PREPARING A FUEL ELEMENT FOR A NUCLEAR REACTOR COMPRISING CRUSHING AND SCREENING FUSED URANIUM DIOXIDE INTO A PLURAITY OF SIZE RANGE FRACTIONS, BLENDING SELECTED SIZE RANGE FRACTIONS, INTRODUCING SAID BLEND INTO A TUBE COMPOSED PREDOMINANTLY OF ZIRCONIUM TO WHICH A LOWER END CAP HAS BEEN WELDED, MOVING A WHISTLE GENERATING HIGH-FREQUENCY SONIC VIBRATIONS ALONG THE LENGTH OF THE TUBE FOR THREE MINUTES, MOVING TWO SUCH WHISTLES ALONG THE LENGTH OF THE TUBE FOR THREE MINUTES, MANUALLY TAMPING THE POWDER IN THE TUBE, AND REPEATING THE APPLICATION OF HIGH-FREQUENCY SONIC VIBRATION AND TAMPLING SEVERAL TIMES, AND THEN CUTTING THE TUBE TO THE DESIRED LENGTH AND WELDING A TOP END CAP THERETO.
