This government report discusses the possibility of using crystalline silicotitanate (CST) as a method of removing cesium from radioactive waste tanks at a storage facility. Thermal conductivity is an important factor in this process as cesium emits thermal energy, the solution used to remove it must be able to manage it or hot spots could develop through the column. The thermal conductivity of CST-air and CST-average stimulant mixtures was measured ...
