摘　　要：介绍了数值反应堆的基本概念,详细调研了国际上针对数值反应堆开展的研发项目,如轻水堆先进仿真联盟(CASL)、欧洲核反应堆仿真通用平台(NURESIM)和核能先进仿真与建模(NEAMS)项目,总结了多物理耦合及多尺度耦合技术的国内外研究现状,并结合研究现状指出材料腐蚀行为与流动传热、中子物理共同作用下的多物理耦合机理、基于统一网格求解的高保真耦合程序开发是数值反应堆技术发展的重点方向。This paper explains the basic concept of numerical reactors,and studies in detail the international research and development(R&D)projects for numerical reactors,such as the Consortium for Advanced Simulation of Light Water Reactors(CASL),European Nuclear Reactor Simulation(NURESIM)platform,and Nuclear Energy Advanced Modeling and Simulation(NEAMS)program.It also presents a further study on and a summary of the current research status of multi-physics coupling and multi-scale coupling technology in China and other countries.In combination with the research status,this paper indicates that the focus of the numerical reactor technology development rests on the multi-physics coupling mechanism under the combined action of material corrosion,flow heat transfer and neutronics,and the development of high-fidelity coupling code based on unified grid solution.
