Treatment of radioactive wastes by plasma incineration and vitrification for final disposal

摘要

Thermal plasma technology takes the advantages to incinerate the combustible parts of radioactive wastes of volume reduction and to vitrify the noncombustible counter parts simultane- ously into glassy slags with very low leaching rate. For developing the proper plasma processes to treat various waste forms, a crucible-type plasma melter and a 10 kg h~-1 plasma furnace system are built at the Institute of Nuclear Energy Research (INER).
