Description

Based on measurements with a He-H2O carrier gas, release fraction values for lanthanum, barium, and strontium gaseous fission product species have been obtained from small-scale core-concrete metals at 2150 and 2385 K. The sample configuration consisted of a layer of limestone or basaltic concrete granules, a layer of urania fuel granules containing La2O3, BaO, and SrO in solid solution, and a metal layer consisting of a mixture of stainless steel and Zircaloy between the fuel and concrete. The following trends in fission product release fraction values were found: Ba > Sr > La. Release fraction values based on measured release of fuel, cladding, structural, and concrete species are presented
