The new technologies such as modularization are developed to secure competition against oversea NPP for APR+ Plant. To reduce the construction period, the SC structure and Half-SC structure modules were respectively applied to exterior wall and slab of the APR+ IRWST. In this paper, partitioning Methods of IRWST module, constructability and construction schedules were analyzed. Consequently, it is concluded that the construction period can be reduced by applying IRWST modules to NPP Construction.
