    • A method of cycling a nuclear fuel for a fast breeder and a minor actinoids annihilation reactor, which provides a nuclear fuel cycle having technical advantages, such as a safety inherent in a nuclear reactor, a short fuel doubling time and a high uranium resources utilization factor, and economical advantages, comprising the steps of: preparing sphere pack type fuel pins including a nuclear fuel containing uranium-plutonium-mixed nitride fuel and a minor actinoids nitride fuel, and a sodium heat bonding material, installing the fuel pins in a reactor core and burning the same, subjecting the used fuel to fused salt electrolysis, converting the uranium, plutonium and minor actinoids deposited on a cathode into a high-order nitride, recovering the high-order nitride, converting the recovered high-order nitride into mononitride, and manufacturing a nuclear fuel, which contains a uranium-plutonium-mixed nitride fuel and a minor actinoids nitride fuel, from the mononitride.
    • 一种为快速增殖和次级act系核湮灭反应堆循环核燃料的方法,其提供了具有技术优势的核燃料循环,所述技术优势例如核反应堆固有的安全性,短燃料加倍时间和高铀资源利用率 以及经济优点,包括以下步骤:制备包括含铀钚混合氮化物燃料和次act系氮化物燃料的核燃料和钠热粘合材料的球形包装型燃料棒,将燃料棒安装在反应堆堆芯中 使用过的燃料进行熔盐电解,将沉积在阴极上的铀,钚和次级act系元素转化成高阶氮化物,回收高阶氮化物,将回收的高阶氮化物转化为单氮化物, 和从单硝酸盐制造含有铀 - 钚混合氮化物燃料和次级act系氮化物燃料的核燃料。
