Contractor KEPCO E & C
Period January 07, 2011 ~ June 30, 2014
Project Information
  • Location
    Bonggil-ri, Yangbuk-myeon, Gyeongju-si, Gyeongsangbuk-do, Korea (nearby Wolsong Nuclear Power Plant)

 

  • Description
    First applied silo type rock caverns for radioactive waste disposal in Asia (H = 50m, D = 27m, 6ea)     

         

            • Technical Issues
              • Design of the silo considering safe construction of a large-scale (H = 50m, D =27m) underground space
              • Excavation and reinforcement plan based on the detailed analysis considering different rock conditions and seawater using 3D geological model
              • Establishment of the new supporting system concept for a large-scale underground space as the first design of the silo type cavern (dome shaped) in Asia
