Description/Abstract:
THIS IS THE FIRST IN A SERIES OF QUARTERLY REPORTS ON THE RESEARCH AND DEVELOPMENT WORK CARRIED OUT FOR ACTIVITY 2790 - SEPARATIONS DEVELOPMENT FOR NON-PRODUCTION REACTORS. BY JANUARY 1962, HANFORD IS TO BE PREPARED TO PROCESS THE FUELS FROM THE POWER REACTORS WHICH EMPLOY DEPLETED OR SLIGHTLY ENRICHED URANIUM FUELS. AT THE PRESENT TIME, HANFORD IS PLANNING TO PROCESS THE FUEL FROM THE FOLLOWING REACTORS: YANKEE, DRESDEN, CPPD, PIQUA, CHUGACH, PRDC, AND NORTHERN STATES. BATCH STUDIES WERE MADE TO DETMINE THE REQUIREMENTS FOR REMOVING CHLORIDE FROM AQUA REGIA DISSOLVER SOLUTION BY SOLVENT EXTRACTION. PRELIMINARY DISSOLUTION AND CORROSIN RATES ARE GIVEN FOR STAINLESS STEEL JACKETS IN HNO3 - HF SYSTEM. THE SOLUBILITY OF UF4 IN BOILING ZIRFLEX SOLUTIONS (NH4HF) CONTAINING DISSOLVED ZR IS GIVEN. ZIRFLEX PILOT PLANT SUTDIES WERE INITIATED ON THE DISSOLUTION OF ZIRCALOY METAL WITH AQUEOUS NH4HF SOLUTION. A WELDED HAYNES-25 COUPON SHOWED NO VISIBLE PREFERENTIAL ATTACK AFTER EXPOSURE TO 5M HNO3-2M HCI FOR 200 HOURS. THE CORROSIN RATE OF 304-L STAINLESS STEEL EXPOSED FOR 312 HOURS TO 6M NH4HF UNDER HEAT TRANSFER CONDITIONS WAS 1.6 MILS/MONTH.
