基于参考电站的核电模块化技术研究

模块化技术是核电站工程缩短建造工期、降低造价的重要技术手段,已成为三代核电的发展方向之一.以目前中国主力核电堆型CPR1000为参考电站,借鉴国内外先进模块化技术,借助自主开发的模块三维设计系统,完成了核电站核岛主厂房的模块总体方案设计.在此基础上,开展典型模块详细设计工作,以实例进一步验证了设计可行性,同时从采购和施工2个方面对模块化技术的实施进行了分析,评估了研究成果在实际工程项目上的技术可行性.

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 isIand 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.
