Abstract

Possibilities in melting were investigated for different modes of operation, e.g., techniques using differentials in slag composition and oxidation rate. Work done by BSC was essentially on the reclamation of steel components removed from several types of UK reactors and designated as radioactive waste. This was done in industrial furnaces. At Siempelkamp, work is being done on the design of a pilot furnace system for enclosed melting and melting of radioactive steel waste in 8 t and 20 t furnace systems with ingot casting. One purpose is to achieve high volume reduction for most efficient storage - disposal of radioactive waste. Another purpose is to get a homogeneous distribution of activity in the ingot. Thus, recycling under certain conditions should be possible. The safe enclosure and filtration systems are main subjects of this research work. In the frame of the second five-year programme (1984 - 1988), new research work will be undertaken on the separation of cobalt from stainless steel by vapour phase transport.
