안전정지지진에 대한 핵연료 및 저장랙의 충격특성 평가

The structural integrity evaluation of a spent fuel and spent fuel storage rack are very important in terms of nuclear safety and waste management. Generally, the spent fuel storage rack (SFSR) is utilized as the purpose for storing and protecting the spent fuel. The objective of this study is to show the validity of the spent fuel as well as SFSR design through a structural integrity evaluation based on a numerical analysis. In particular, a dynamic time history analysis considering the gaps between the spent fuel and the walls of the storage cell pipes in the SFSR and impact analysis was performed to check the structural integrity of the spent fuel and storage cell pipe.
