The polar crane module in the reactor containment building has been reviewed to reduce the construction period and the workload on high elevation. In this paper, a numerical analysis for a lifting lug of the polar crane module was performed to confirm the structural integrity of the lug. The numerical analysis was also performed to check the structural integrity of the polar crane module. In regards of installation process, the constructability of the polar crane module was reviewed as well. Consequently, it is concluded that the reduction of construction period is possible.

The rebar module in the common basemat of the reactor containment building has developed to reduce the construction period. In this paper, three stages of concrete pouring were reviewed for the possible application of the rebar module. The lifting frame design was done to lift the rebar module and the construction simulation was done to check the interface in the construction process.
