System Design of Underground Facility for Spent Nuclear Fuel Storage
The design of the final nuclear repository design has been initiated by SKB and as a first step the system design of the underground facility has been executed. Itasca has taken part in the project with responsibility over rock mechanical problems and analyses. The work included support of layout decisions through analyses and rock mechanical expertise. The analyses with FLAC and FLAC3D were mainly focused on the rock stress redistributions around the facility. The work involved finding the amount of tunnels and shafts in different rock domains, as well as necessary rock reinforcements. The system design work also included risk analysis of the project.
