METHODS FOR CHARACTERIZATION OF RADIOACTIVE WASTE AND SPENT NUCLEAR FUEL. RESULTS OBTAINED DURING THE VALIDATION

In order to reduce radioactive risk on short term and long term for the environment and population, the radioactive waste has to be treated, conditioned and stored in appropriate conditions. In every country the regulatory body for nuclear activities establishes acceptance criteria for storage or disposal of radioactive waste package. In order to satisfy requirements for radioactive waste characterization, in the frame of the National Program of Research and Development, the “Laboratory for characterization of spent nuclear fuel and high/medium level radioactive wasteLABORAD” was created. The purpose of the project was to accredit the analysis methods available in the laboratory, and also to develop new methods for the characterization of the radioactive waste. Experimental results and performance obtained during validation of the methods will be presented in this paper. Also new methods for radioactive waste characterization based on quadrupole ICP-MS are under validation in the laboratory.
