51 Advantages of Modularized Construction Progress Perspective: The fabrication and assembly of modules could be performed outside of NI and in parallel with the civil construction inside NI, which accelerates the construction progress. Quality Perspective: Modules are fabricated in specialized fab-shops off site and assembled on site assembly area, which facilitates quality control. HSE and Housekeeping Perspective: The prefabrication and assembly of modules are done outside of the NI, which reduces the work quantity on NI site and is beneficial i lfor safety and dhousekeeping management. -51-

52 Prerequisite of Modularized Construction The key prerequisite to achieve modularized construction is the matching between module fabrication and site construction logic, i.e., the design and fabrication of modules must meet the need of site construction. Module Design Module Fabrication Modularized d Construction Site Construction -52-

53 Future Outlook on AP1000 Modularized Construction Trend of the future Modularized construction will lead the way for the development of future projects, we could foreseen the advantages of modularization construction, it could be fully demonstrated once the design and fabrication of modules could go hand in hand with construction progress and construction sequences. -53-
