STRATEGY FOR THE FRACTIONATION OF HLW FROM SNF REPROCESSING

The paper considers the main prerequisites of the fractionation strategy for HLW from SNF reprocessing. It analyses the composition of HLW resulting from SNF reprocessing taking into account the requirements for the quality of the glass compound and the criteria forming the basis of the classification system for solidified radioactive waste. The paper evaluates the opportunities for renouncing the idea of deep HLW disposal. It proposes basic HLW fractionation options with an assessment of their feasibility considering the engineering tools available. For the proposed strategies, the paper evaluates the volumes of solidified RW fractions and the RW disposal cost. Based on the calculations performed, it also presents the postulates of the fractionation strategy.

Keywords: spent nuclear fuel, reprocessing, high-level waste, fractionation, minor actinides, radioactive waste.
