乏燃料储运用中子吸收材料的专利研究

Patent Examination on Neutron Absorbing Material Applied to Storage and Transportation of Spent Fuel

中子吸收材料的开发和制备技术是核电站乏燃料储运设施的关键技术,目前被国外企业垄断。从专利角度分析了技术的主要来源国和机构,指出含硼中子吸收材料尤其是含硼不锈钢和B4C/Al是研究的热点,为我国实现中子吸收材料国产化提出建议。

Development and preparation of neutron absorbing material is a key technology for spent fuel storage and transportation facilities in nuclear power station, currently it is monopolized by foreign companies. By analyzing the main origin countries and organizations of the technology from the view point of patents, it indicates that boraeic neutron absorbing material especially boracic stainless steel and B4C / Al should be the hotspot for research. This paper also put forward recommendations for our country on localized manufacturing of neutron-absorbing material.
