T
he CEA develops for several years different kind of process
in order to treat nuclear wastes. It has appeared that some
of them could be used to destroy other industrial hazardous
wastes such as organo-halogenated liquids or others, largely
used as precursor in chemical industry. These processes have
the particularity to involved plasma tools in order to reach very
high temperature level leading to get very good destruction
efficiencies. Thermal and UV photoactivity of the plasma can
be simultaneously used to reach the best results. The present
paper provides the description of three different thermal
processes developed at the CEA to treat radioactive liquid waste:
the SHIVA process using bipolar twin torches that involve
transferred arc plasma. The IDOHL process involving inductive
coupled plasma torch and the ELIPSE process working with an
underwater blown arc plasma torch. An additional technology
will be presented: The one using cold plasma as corona pulsed
discharges in order to design very efficient and enduring filtering
system. These systems are intrinsic and in dissociable of very
safe and reliable processing. The studies performed on semi
industrial or on industrial mockup provide very attractive results
showing that these processes could be applied for different kind
of waste, nuclear or not. Example of plasma application – The
ELIPSE process (submerged plasma process for pure organic
liquid treatment)
