As the capacity of spent nuclear fuel storage pool at reactor sites becomes saturated in ten years, long term dry storage strategy has been recently discussed as an alternative option in Korea. In this study, we reviewed safety-criteria-related research results on spent nuclear fuel performance and ...

건식저장 방법이 현실적인 대안으로 떠오르는 이유는 무엇인가? | 이 기간이 끝난 후 사용후핵연료를 처분하는 방법은 심지층에 영구 처분하거나, 혹은 재처리 후 발생하는 고준위 폐기물을 영구처분하는 방식이 있다. 현재 우리나라는 아직 최종 처분 방식을 결정하지 못하고 국내 경수로에서 발생된 사용후핵연료 모두를 발전소 내 수중 저장조에서 보관되고 있다. 그러나 국내 원전의 저장조 용량의 한계로 2025년경에는 이 시설이 포화될 것으로 예상되고 있다. 따라서 사용후핵연료를 처분하기 위한 그 중간단계로 사용후핵연료를 공기나 불활성 기체로 채워진 별도의 용기에 저장하는 건식저장 방법이 현실적인 대안으로 부상하고 있다. | |
건식저장 방식의 장점은 무엇인가? | 따라서 사용후핵연료를 처분하기 위한 그 중간단계로 사용후핵연료를 공기나 불활성 기체로 채워진 별도의 용기에 저장하는 건식저장 방법이 현실적인 대안으로 부상하고 있다. 건식저장 방식의 경우 안전성, 경제성 측면에서 유리한 것으로 평가되고 있으며 최근에는 대부분의 국가에서 이 방식을 이용하고 있는 추세이다. | |
사용후핵연료의 건식저장에 관한 논의가 활발한 이유는 무엇인가? | 최근 국내에서도 원전 부지 내에 건설된 습식저장조의 용량이 곧 포화될 것으로 예상되어 사용후핵연료의 건식저장에 관한 논의가 활발하다. 이 논문에서는 앞으로 다양하게 논의될 저장시스템의 안전성과 함께 장기 건식저장 시 발생하는 사용후핵연료의 특성 및 건전성 변화에 대해 이제까지 국내외에서 연구 보고된 내용들을 면밀히 검토하고 향후 추구해야 할 연구방향을 제시하고자 하였다. |
