             abstract = "Thermal plasma technology is a process that demonstrates high 
                         performance for the processing of differ-ent types of waste. This 
                         technology can also be applied in the treatment of radioactive 
                         wastes, whichrequires special care. Beyond that, volumetric 
                         reduction, inertization, as well as a cheap and efficient pro-cess 
                         are necessary. In this context, the purpose of this paper is to 
                         demonstrate the application of thermalplasma technology for the 
                         treatment of solid radioactive waste. For this, stable Co and Cs 
                         were used tosimulate compactable and non-compactable radioactive 
                         waste; about 0.8 g Co and 0.6 g Cs were addedin each experimental 
                         test. The experimental tests were conducted using plasma of 
                         transferred arc electricdischarge generated by the graphite 
                         electrode inside the process reactor. The behavior and 
                         distribution ofthe radionuclides present in the waste were 
                         assessed during the plasma process. The results show thatthe 
                         significant amounts of Co and Cs leave the melt by volatilization 
                         and are transferred to the gas phasewith a small portion retained 
                         in the molten slag. The retention rate of Co in the slag phase is 
                         about 0.03%and 0.30% for compactable and non-compactable waste, 
                         respectively. On the other hand, Cs is completelytransferred to 
                         the gas phase when added to the compactable waste. Conversely, 
                         when in the non-compactable waste, only 1.4% Cs is retained.",
