Schulz, W W; Dressen, A L

Complex radioactive ferrocyanide compounds result from the scavenging of cesium from waste products produced in the chemical reprocessing of nuclear fuel. These ferrocyanides, in accordance with this process, are converted to an immobile glass, resistant to leaching by water, by fusion together with sodium carbonate and a mixture of (a) basalt and boron trioxide (B/sub 2/O/sub 3/) or (b) silica (SiO/sub 2/) and lime (CaO). 7 claims.
