Abstract
concentration of fission products, APPR plate melted at 1525 deg C and released 50% of the rare gases, 33% of the iodine, 9% of thc cesium, and traces of strontium. After 25% burnup the cesium value rose markedly to 41%, while the iodine value apparently declined to 12%. Aluminum alloy at 700 deg C released only 2% of the iodine and lO% of the rare gases. Zirconium alloy, after 15% burnup, melted at 1850 deg C in air and released all of the rare gases, 26% of thc iodine, 10% of the cesium, snd less than 1% of the strontium. When melted in steam, approximately 2% of the strontium and 0.5% of the barium were also released from zirconium alloy. Exploratory expriments were performed with Geneva-type aluminum-dispersion fuel, UO/sub 2/, and GE-HTRE fuel. (auth)
