Radioactive Waste Treatment and Conditioning Plant
Objectives:
- Collecting, treatment and conditioning of the radioactive waste resulted from the Nuclear Fuel Factory (FCN), the TRIGA reactor, Post-Irradiation Examination Laboratory (LEPI) and other nuclear installations within SCN and in the country;
- Studies related to the development and implementation of new equipments and technologies in the rad waste management field.
Activities:
- Process lines for treatment and conditioning of radioactive waste:
- Installation for treatment by evaporation of liquid low-level beta-gamma radioactive waste;
- Installation for conditioning in concrete of the radioactive concentrate obtained from evaporator; the installation is also used for conditioning in concrete of the solid radioactive waste, radioactive spent sealed sources and organic liquid waste (oils, solvents and scintillation cocktail) from Cernavoda NPP;
- Installation for treatment and bituminization of spent ion exchangers;
- Installation for treatment of liquid radioactive waste resulted from the nuclear fuel fabrication;
- Installation for treatment through incineration of solid radioactive waste resulted from the nuclear fuel manufacture;
- Installation for decontamination of sub-assemblies;
- Laundry for decontamination of individual protective outfits.
- The research activity includes:
- Studies for the development of treatment and conditioning technologies of all radioactive waste types generated by Cernavoda NPP;
- Studies for preliminary safety assessment of L/IL waste disposal from Saligny;
- Design and qualification of the different containers for radioactive waste storage, transport and final disposal.
Experimental Facilities:
- Multi-channel gamma spectrometry chain with hyper pure Ge detector;
- Atomic absorption spectrophotometer capable of in flame and in pure graphite tube analysis;
- Spectrophotometer UV-VIS.
