Abstract

To maintain sustainability of nuclear energy as an important energy source, both safety problem and Spent Nuclear Fuels(SNFs) problem should be solved. In case of Gen-IV reactors such as fast reactor, SNFs can be used as fuels by using fast neutrons. It can be a suitable treatment method of high-level waste in near future. Liquid metals such as Sodium or Lead-Bismuth Eutectic (LBE) can be possibly used as a coolant to use fast neutrons. In this paper, it was described that natural circulation parameter studies, design analyses, material selections and a completion of facilities. To develop a natural circulation facility, thermal hydraulic analyses were performed. Installation technique of liquid metal natural circulation were secured.

원자력 발전이 중요한 에너지 공급역할을 담당하기 위해서는 안전성을 확보하고, 사용 후 핵연료 문제를 해결하여야 한다. 이와 같은 문제를 해결하기 위한 방안으로 소듐이나 납비스무스 공융합금 등과 같은 액체금속을 냉각재로 이용하는 방안이 연구되고 있다. 본 논문에서는 액체금속 유동모사 실증 설비 개발을 위한 설계변수 검토, 설계 해석, 구조재의 선정 및 설비 개발 결과를 서술하였다. 설비의 개발은 열수력 해석코드의 해석을 통해 수행되었고 충분한 자연순환 유량을 갖는 설비제작 기술을 확보하였다.
