Original title: China's fourth generation fission nuclear reactors "core" technology has made important breakthroughs in
Xinhua News Agency, Hefei, April 6 (reporter Cai Min)-6th learned from the Chinese Academy of Sciences Institute of nuclear safety technology, the advanced research team in fourth generation fission nuclear energy reactor core made important breakthroughs in core technologies, developed a new fuel Assembly and cladding materials, share high solve lead-based reactor fuel, high density cooling, heat-resistant corrosion-resistant structural materials and other key technical problems. This achievement to break the foreign monopoly, achieving the fourth generation nuclear fission reactor core ownership.
Lead-based heap is "fourth-generation nuclear energy systems international forum (GIF)" organizational assessment is expected to first achieve industry demonstration and commercial application of fourth-generation nuclear reactors. Benefit from lead-based material excellent Neutron Physics and Thermo-physical properties and stability of property, lead-based heap has the advantage in terms of production safety and economy, also has good nuclear waste "incineration" processing capability and nuclear proliferation, is able to achieve a variety of applications, and advanced nuclear energy systems for sustainable development. Western countries are now actively promote the application of lead-based reactor project, planned 20 's business model.
Fuel components and cladding is lead-based reactor core components, structural design and the materials used by the core challenges of complex service environments.
By the China nuclear society Li Guanxing, academician of CAs, Shanghai University, Zhou Bangxin, President of academicians, Wang Li dequn expert group of academicians and renowned experts, has recently developed by the Chinese Academy of Sciences, nuclear safety "China lead-based reactor prototypes of fuel components and cladding materials" result. The expert group agreed: China lead-based reactor prototypes fuel assemblies and achieve the independent development of cladding material, has filled the domestic blank, new cladding materials for high temperature and corrosion resistance in the international advanced level, is important for promoting the innovative development of liquid metal cooled reactor in China.
According to reports, the lead Foundation has been selected as a strategic guide science and technology programs of the Chinese Academy of Sciences "future advanced nuclear fission energy evolution system-ADS" and "Twelve-Five" major infrastructure construction project "research on Accelerator-driven transmutation device" reactor systems. Chinese Academy of Sciences is responsible for nuclear safety "ADS transmutation systems," lead-based research and development, has now completed a reactor system design and its key technology research and development, and core design concepts and development of key equipment has achieved a breakthrough, with a lead-based reactor project implementation capacity.

我国掌握第4代核裂变反应堆核心技术 打破垄断|核心技术|核裂变_新闻资讯
原标题：我国第四代核裂变反应堆核“芯”技术取得重要突破
新华社合肥4月6日电（记者 蔡敏）记者6日从中科院核能安全技术研究所了解到，该所先进核能研究团队在第四代核裂变反应堆堆芯核心技术上取得重要突破，研发出新型燃料组件及包壳材料，解决了铅基堆堆芯高份额燃料、高密度冷却剂、耐高温耐腐蚀结构材料等关键技术难题。这一成果打破了国外相关技术垄断，实现了第四代核裂变反应堆核心技术自主掌握。
铅基堆被“第四代核能系统国际论坛（GIF）”组织评定为有望首个实现工业示范和商业应用的第四代核裂变反应堆。得益于铅基材料优良的中子物理和热物理特性以及稳定的化学性质，铅基堆在产能安全性和经济性方面具有突出优势，还具有良好的核废料“焚烧”处理能力和核燃料增殖能力，是一种能够实现多种应用和可持续发展的先进核能系统。西方多个国家目前正积极推动铅基堆工程化应用，计划本世纪二十年代实现商业示范。
燃料组件及包壳是铅基堆堆芯的核心构件，其结构设计和所用材料受到堆内复杂的服役环境的挑战。
由中国核学会理事长李冠兴院士、上海大学周邦新院士、华中科技大学李德群院士及行业内知名专家组成的专家组，近日对中科院核安全所自主研发的“中国铅基堆原型燃料组件及包壳材料”进行了成果鉴定。专家组一致认为：中国铅基堆原型燃料组件及包壳材料实现了自主化研发，填补了国内空白，其中新型包壳材料的耐高温和耐腐蚀性能处于国际先进水平，对促进我国液态金属冷却反应堆创新发展具有重要意义。
据介绍，铅基堆已被选作中国科学院战略性先导科技专项“未来先进核裂变能－ADS嬗变系统”和国家“十二五”重大基础设施建设项目“加速器驱动嬗变研究装置”的反应堆系统。中科院核安全所负责“ADS嬗变系统”中铅基堆的研发工作，目前已经完成了反应堆系统详细设计及主要技术研发，并在核心设计理念与关键设备研制方面实现了突破，具备了铅基堆工程实施能力。
