Waste characteristics evaluating strategy of KRR1 and 2 reclassified waste by applying in IAEA TECDOC 1537 (Strategy and methodology for radioactive waste characterization)

These reclassified wastes have historical specificity and extremely lowlevel wastes. While, even they are extremely low, still it needs to perform same process to disposal but it would be inefficient for these wastes. Therefore, it is believed that establishing a strategy for characterization evaluation in accordance with the IAEA report will help to carry out similar types of decommissioning waste disposal in the future. In the case of reclassification process in the KRR, it has very low level activity limit. In addition, classification by stream has no actual meaning in the past history of waste disposal by KRR Based on these findings, it is necessary to classify the characteristics evaluation groups for securing as many specimens as possible in order to evaluate the characteristics of KRR reclassified wastes. Usingconservative limits for Waste Acceptance Criteria satisfaction will be a way to identify adequate and cost effective characterization requirements
