The ACR^[○!R] (Advanced CANDU[○!R] Reactor), developed by Atomic Energy of Canada Ltd. (AECL[○!R]), is designed with constructability considerations as a major requirement during all project phases from the concept design stage to the detail design stage. For ACR-700,a project schedule of 48 months has been developed for the nth replicated unit with a 36 month construction period duration from First Concrete to Fuel Load. AECL, recognizing the immense benefit of collective experience, is partnering with Hitachi Ltd in the development of the ACR power plant design. AECL has gained valuable experience in implementing new construction methods at the Qinshan (Phase III) twin unit CANDU 6 plant in China, and Hitachi likewise has enjoyed success in modular construction of ABWRs in Japan. Utilizing these experiences, AECL is developing the ACR nuclear steam plant (NSP) and Hitachi is developing the Turbine Building. An overall construction strategy, which builds on the success of these construction methods from the nuclear power plant developments in China and Japan, has been developed for the ACR. The overall construction strategy comprises the "Open Top" construction technique using a Very Heavy Lift crane, parallel construction activities, with extensive modularization and prefabrication. Modules and prefabrications are major features of the ACR design, resulting in an excess of 80% of Reactor Building internal work being completed as modules or as very streamlined traditional construction. This paper reviews the ACR construction strategy and provides examples of modules and how they impact on the ACR construction schedule. In conclusion, the ACR-700 is designed using the latest, proven construction methods to achieve a 36 month construction period for the nth replicated unit.
