Research of Modular Technology for Nuclear Power Projects Based on Reference Nuclear Power Plant

As an important technology which can effectively shorten the construction period and reduce the cost of nuclear power projects, the modular technology has become one of the development trends for the third generation of nuclear power plants. Taking the present mainstay CPR1000 nuclear power reactor as reference plant and absorbing the advanced foreign modularization technologies, the overall concept design of main buildings of the nuclear island is completed with the independently-developed 3-D modular design system. On this basis, the detailed design for typical modules is carried out so as to verify the feasibility of the technology. Besides, an analysis on implementation of modular technology is performed from the aspects of procurement and construction so as to evaluate the feasibility of the research achievements for practical engineering projects.
