Zusammenfassung:A method of reducing the volume of used fuel for heavy water according to the present invention has a volume reduction effect of more than 40% as compared with the conventional used fuel bundle for a heavy water reactor, thereby reducing the area of an intermediate storage facility and the cost of all processes. In addition, the separated bonded plate will be classified as low level waste instead of high level waste so as to have a generation reduction effect of the high level waste. 본 발명에 따른 중수로용 사용후핵연료의 용적 저감 처리 방법은 기존 중수로용 사용후핵연료 다발 대비 40% 이상의 체적 저감 효과가 있으며, 이를 통해 중간 저장시설과 영구 처분시설의 부지 면적 및 제반 처리비용을 크게 줄일 수 있다. 또한 분리된 봉단접합판은 고준위 폐기물이 아닌 중저준위 폐기물로 분류되어 별도 처리할 수 있으므로 실제 고준위 폐기물의 발생 저감 효과가 더 클 것으로 기대된다.
