Melt Treatment for Conditioning of Drums Produced During Soil Reclamation of Low Activity Trenches

In the past years, many studies had been carried out in the ITREC Plant, located in ENEA – Trisaia Research Centre, in the field of nuclear fuel reprocessing and with re-fabrication techniques to the Th-²³³U cycle as an alternative to the U-Pu cycle. During these activities low level solid wastes were produced, containerised, stored into trenches and progressively covered with earth. In the 1980’s the trenches were reclaimed obtaining 3000 drums (200 liter volume) of solid LLW and about 6000 drums of low contaminated soil. In this presentation are described the action of reclamation of the trenches, sealing the low contaminated soil, and the melting campaign of contaminated drums.
