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.
