摘要
快中子堆在最终解决世界能源问题中占有十分重要的地位,碳化硼是快中子堆国际普遍接受的中子吸收材料,作者综述了快堆对材料的要求以及碳化硼的优点和限制,评述了碳化硼芯块密度、硼碳比、晶粒度、热传导率、杂质铁含量等对作为寿命限制参数的氦释放率和肿胀率的影响,提出了材料设计的观点。
Fast breeder reactors play an important role in the final solution of the world energy crisis. Boron carbide is the general accepted neutron absorber material for fast breeder reactors. The material requirements of fast reactors and advantages and limitations of boron carbide were commented. The effect of boron carbide core density, boron carbon ratio, grain size, heat conduction rate, impurity.iron content, etc, on the helium release ratio and swelling ratio, which are considered as the factors of life time limitation of material, were analysed. It presented the concept of design of material.
