표층처분시설 처분고의 채움단계 별 지진해석을 통한 최대주응력 및 최소주응력 분석

초록

Currently, South Korea is in the process of building a near-surface disposal facility, a second-stagedisposalfacility, as a precaution against low-level radioactive waste from nuclear power generation. The UnitedStatesandEuropean-Union (EU) define nuclear energy as green energy. conditions for nuclear investment to be consideredanenvironmentally friendly activity include establishing a detailed plan for the safe disposal of waste. After the treatmentofradioactive waste in the surface disposal facility disposal vault, a structural health monitoring systemshouldbeinstalledfor the disposal vault for safe maintenance. In this study, the seismic analysis of the near-surface disposal vault will beanalyzed by finite element analysis according to the using stage. In this study, analyzing the maximumprincipal stressandthe minimum principal stress can occur in structures by performing seismic analysis for each using stage of thesurfacedisposal facility through finite element analysis.
