2001年初,快堆工程部组织选厂,进行材料及组件研制,截至2001年11月底,已完成了热压碳化硼芯块、元件棒包壳管、六角形外套管、元件棒定位绕丝及核级固溶棒的试制,并加工了2组碳化硼屏蔽组件、2个不锈钢反射层组件的管脚,供堆外水力学和结构稳定性试验用,3根碳化硼元件棒供堆内快中子辐照用。试制取得了成功。 快堆堆芯组件结构材料为核级316（Ti）不锈钢,化学成分要求严格,金相组织要求高,六角管及包壳管的尺寸精度高,表面质量高,几乎无缺陷。碳化硼芯块为核级,在化学成分、密度、晶粒度、尺寸公差、碳硼比等方面要求亦很高。经上钢五厂、上海异型钢管厂、上海钢研所及中南大学粉冶所的努力,生产出了合乎质量要求的产品。
In early 2001, the Fast Reactor Engineering Department organized the selection of plants for material and component development. As of the end of November 2001, the hot pressing of boron carbide pellets, component rod cladding tubes, hexagonal outer casing tubes, Nuclear-grade solid solution of the trial of the rod, and processing of two sets of boron carbide shielding components, two stainless steel reflective layer components of the pin for hydraulics and structural stability test, three boron carbide rods for fast reactor Neutron irradiation. Trial production has been successful. The reactor core material is made of 316L stainless steel with strict chemical composition, high metallurgical structure, high dimensional accuracy of hexagonal tubes and cladding tubes, high surface quality and almost no defects. Boron carbide pellet is a nuclear grade, and its chemical composition, density, grain size, dimensional tolerance, carbon to boron ratio and other requirements are also very high. After the five plants on steel, Shanghai Shaped Steel Tube Plant, Shanghai Steel Institute and the Central Plains Metallurgical Institute’s efforts to produce the products meet the quality requirements.
