원자력시설 해체 시 극저준위방사성폐기물 처분을 위한국내외 방사성폐기물 분류체계 및 인수기준에 대한 연구 = Review Study of Radioactive Waste Classification and Waste Acceptance Criteria for Disposal of VLLW from Decommissioning of Nuclear Facilities

다국어 초록 (Multilingual Abstract)

Waste acceptance criteria (WAC) for disposal of very low level waste (VLLW), which isgenerated in large quantities during decommissioning of nuclear facilities should be developed. Forthe WAC development, it is required to investigate current status to develop WAC for disposal ofVLLW. The objective of the present study was to investigate radioactive waste classification andWAC for disposal of VLLW from decommissioning of nuclear facilities. Each country developed itsown system for the classification of radioactive waste. Therefore, the classification system for radioactivewaste in each country was analyzed to review its WAC of the radioactive waste, which is equivalentto the VLLW in the Korea waste classification system. The category of the VLLW in the wasteclassification systems of the International Atomic Energy Agency (IAEA) and the United Kingdom(UK) was similar to the category of the VLLW in the waste classification systems of Korea. For theUnited States (US), the category of Class A was similar to the VLLW in the Korea system. The IAEAprovided the general guidance for the WAC based on the safety assessment of disposal system. TheUS and the UK developed the WAC based on national radioactive waste disposal policy and characteristicsof disposal facilities and radioactive waste in addition to the IAEA general guidance. Therefore,the WAC for disposal of VLLW in Korea should be developed by considering the nationalradioactive waste disposal policy, characteristics of disposal facilities, and the IAEA guidance. Thisstudy results will contribute to establishment of national management system of radioactive waste.
